Ms7821: Add image for Android instructions

== Android ==
=== App ===
You can use our Android App to configure the correct WiFi settings on your Android device. Download it here:

* From Google Playstore: https://play.google.com/store/apps/details?id=nl.eventinfra.wifisetup
* Source-code: https://github.com/EventInfra/wifisetup
* APK download: https://eventinfra.org/emfcamp/app-release.apk

[[File:Connecting-to-emfcamp-on-android.png|right|thumb|frame|150px|Connecting on Android]]
=== Manually ===
If you don't want to use the app, download the [https://letsencrypt.org/certs/isrgrootx1.pem ISRG Root X1], and [https://support.google.com/pixelphone/answer/2844832 install it] into your device's '''Wi-Fi certificate''' store, giving it any name you like. Then connect to the '''emfcamp''' network using the following information:

{|padding
| EAP method || TTLS ''(not TLS)''
|-
| style="padding-right: 1em" | Phase 2 authentication || PAP
|-
| CA certificate || ''(whatever name you gave the ISRG Root X1)''
|-
| Domain || radius.emf.camp
|-
| Identity || emf
|-
| Password || emf
|}

It's fine to leave '''Online Certificate status''' as "Do not validate", and leave the '''Anonymous identity''' blank.

== Linux, etc. ==
=== Network Manager ===
You can use the following config file:

Please note that some versions of NM are buggy and will only work with 802.1X using MSCHAPv2, or not at all. If that affects you, it may be easiest to use wpa_supplicant.

Ms7821: /* Client Settings */

[[Team:NOC]] has tried to build and support the fastest network for you: a network comparable to a medium sized ISP, built up in just a couple of days. It might not be perfect all the time. We will be providing blanket wireless coverage and wired network access to both venues and camping tents.

=== Key points ===

* To use the camp WiFi on most modern devices, connect to the '''emfcamp''' network with a username of '''emf''' and a password of '''emf'''.
* You have a public IP address and there is limited network firewalling or filtering. [[#Security|Keep safe!]]
* Don't set up your own wireless access point. This is a serious problem in such a dense event and [[Network/Rogue Access Points|here's why]].

== Wireless ==

<dl>
<dt>Network Name (SSID)</dt>
<dd>emfcamp</dd>
<dt>Username</dt>
<dd>emf</dd>
<dt>Password</dt>
<dd>emf</dd>
</dl>

The whole field has been covered with many wireless access points to ensure the best possible coverage and to allow you to roam seamlessly without interruption. Please note that your device will be reachable by anyone on the internet, please take suitable precautions such as turning on a firewall, and making sure your software is up to date.

You should not bring your own wireless access point, its unlikely to provide better service than the camp ones, and it makes the network worse for everyone else. Any rogue access points will be hunted down and disconnected from the network - see [[Network/Rogue_Access_Points]] if you want to know why. If you have a project that needs to provide its own AP for some reason please contact the NOC and we will find an alternative solution.

Here is the complete list of wireless networks (SSIDs) available:

{| class="wikitable"
! emfcamp
| This is 2.4GHz + 5GHz and should you should use this one in preference, if you can see it. This is the most secure, WPA2-Enterprise.
|-
! style="white-space: nowrap" | emfcamp-insecure22
| '''Warning: insecure''' This is both 5GHz and 2.4GHz, and is for older devices that don't support WPA2-Enterprise. It's unencrypted, and people will likely intercept your traffic. Filtered connection with public IP address. Inbound connections from the rest of the campsite are possible, inbound connections from the Internet are blocked.
|-
! spacenet
| This is 2.4GHz + 5GHz and WPA2-Enterprise, you can connect with a valid account if your hackerspace offers.
|-
! eduroam
| This is 2.4GHz + 5GHz and WPA2-Enterprise, you can connect with a valid account if your university/college/school is offering eduroam. More information can be found at [https://www.eduroam.org/ eduroam.org].
|}

When connecting to any of the WPA2-Enterprise password, which require a username and password, you can use the following (case-sensitive):

{| class="wikitable"
! Username
! Password
! Result
|-
| emf
| emf
| Filtered connection with public IP address. Inbound connections from the rest of the campsite are possible, inbound connections from the Internet are blocked.
|-
| allowany
| allowany
| Unfiltered connection with public IP address
|-
| outboundonly
| outboundonly
| Filtered connection with public IP address. Inbound connections from the Internet or camp-site are not possible.
|}

Use of the 5GHz SSIDs is recommended if your device supports them. 802.11b is disabled as it slows everyone else down.

Even if you are using an encrypted network, you should still [[#Encryption|encrypt any sensitive traffic]] sent over the air end-to-end to prevent snooping. Although some SSIDs offer encryption, it is only over-the-air.

We have airtime fairness configured on our wireless controllers, so if you wish to use a lot of bandwidth (e.g. stream videos or download large files), please use a [[#Wired|wired connection]].

==== Client Settings ====
Also see [[Network/802.1X client settings]] for a list of OS-specific client settings.

SSID: emfcamp

EAP-TTLS:

Phase 1: EAP-TTLS
Phase 2: PAP

PEAP:

Phase 1: PEAP
Phase 2: MSCHAPv2 or EAP-MSCHAPv2 or PAP

CN = radius.emf.camp
CA = ISRG Root X1

SHA256 Fingerprint = B8:3B:F9:39:C4:F2:BF:D0:87:D7:93:5C:A0:DD:18:F3:31:7B:DD:B1:EC:88:3B:22:E0:B2:39:CB:7C:F8:FD:43

Make sure '''you check the certificate''' in order to know you are connecting to the correct network (you should check on both the CN and the CA). Check [[Network/RADIUS_certificate|here]] for the complete certificate.

[[File:Ubuntu network settings.png|thumb|Ubuntu network settings]]
On Ubuntu/Debian based distros the certificate file can be found in /etc/ssl/certs/ISRG_Root_X1.pem

'''Android'''

This app will help you get set up: https://play.google.com/store/apps/details?id=nl.eventinfra.wifisetup. Or follow [[Network/802.1X_client_settings#Manually|these instructions]] to do it manually.

== Wired Ethernet ==

All camping areas are within 60m of a datenklo (or data toilet), where you can connect to the network. If you intend to do so please bring 60-70m of CAT5 cable as we are unable to provide any.

Lay your own cable neatly from your tent back to the nearest Datenklo, and leave 6m of slack coiled on the floor in front of it. And please lay it so that it can be clearly seen that it needs to be plugged in - or you risk having your cable overlooked. At regular intervals a member of the NOC team will connect it up and enable the port.

If you wish to be removed from a Datenklo again on Sunday or Monday, leave your entire cable coiled outside the DK and we will disconnect it. If you need to leave before then, contact the [[Team:InfoDesk|helpdesk]] directly.

All of our edge ports are at least 100 Mbps or 1 Gbps, auto-negotiate, auto-MDX. We are unlikely to have PoE ports for general use.



== Static IPs ==

If you need a static IP on the wired network, contact the NOC.

== IPv6 ==

Naturally, IPv6 is available throughout the network and should "just work" for you. Team:NOC does not recommend disabling IPv6 if you have problems, instead try to understand the problem you are experiencing and get educated in the new world order. Contact the [[Team:InfoDesk|NOC helpdesk]] if you need help.

== Services ==

* DNS: 78.158.87.11 and 78.158.87.12
* NTP: 78.158.87.11 and 78.158.87.12 (ntp1.emf.camp and ntp2.emf.camp)
* Nearest Debian mirror: http://debian.mirror.uk.sargasso.net

== Security ==

=== Encryption ===

Please treat the network as wide open and full of attackers. Although [[Team:NOC]] themselves will not monitor the network, always assume that Alice flirting with Bob will be spied upon by The Third Party.

Any sensitive information including passwords must therefore be encrypted. Please make sure you don't use any software or web applications that send sensitive data or passwords in the clear.

The following mechanisms should be safe:
* Anything that goes through a VPN
* Any website that uses HTTPS
* Any application that uses SSL
** In the case of email, you need to have SSL enabled for both receiving mail (POP, IMAP) and sending it (SMTP)
* ssh and scp
* Where possible, use One-time passwords. Real tokens work best, many of those should be compatible with open source radius servers. [http://perlmonks.org/?node=967433 Here] is a simple Perl radius server implementation for [http://tools.ietf.org/html/rfc6238 RFC6238] tokens that works with ssh and other stuff on linux.

The following are almost always unsafe:

* FTP with login/password (are almost always sent in the clear)
* Telnet with login/password
* Email if you don't use SSL
* Webmail that doesn't use HTTPS
** Someone could trigger a password reminder and then intercept your email
* Websites that use HTTP (not HTTPS) where you need to fill in a password in the page itself

Possibly unsafe, make sure that you understand what you're doing:

* Websites where you need to fill in a password and your ''browser'' (not the website!) tells you it's going to be sent securely
* Websites that require an account but remember you're logged in
** The password ''may'' be protected but not the content or cookies that automatically log you in
* Any time your browser or other application brings up ''anything'' to do with a certificate
* Anything not protected with SSL: someone could be faking DNS answers to impersonate certain sites

Remember: if you're being stupid someone may feel the need to teach you a security lesson in a not so subtle way! (No, that doesn't mean it's ok to hack people just to see if their security is in order.)

=== Firewall ===

On the wired network there is no network firewall and on the WiFi network there is limited firewalling in place. We operate an unfiltered network that is wide open to the Internet. There is no NAT, and everybody has a public IP address. This is our definition of "network neutrality" - a network that doesn't do anything whatsoever to your IP connection.

If you are used to feeling secure just because you've been sitting behind a NAT router, think again. You are now wide open to the whole Internet. Ensure your personal firewall is enabled and set to "Public Network" and that you have applied all security updates to your OS and applications.

By default the WiFi network allows inbound connections from the rest of the campsite, but inbound connections from the Internet are blocked. If you want to ensure no inbound connections are possible towards your WiFi device, use the "outboundonly"-login.

In case you want to enable inbound connections towards your WiFi-device, use the "allowany"-login.

== FAQ ==

=== Can I bring a server? ===

Sure. You can host a server anywhere on the network, and the long DHCP lease time will effectively give you a static IP address.

If you would like to house your server in our data centre (NOC-DC), please contact us before the event by e-mail to noc@. 1 Gbps copper ports are standard; if you require a 10 Gbps port, you'll need to supply a DAC or SFPs (our end Arista-coded) with fibre.

=== Is there a server I can use to host data on site? ===

Due to lack of demand at the last event, this will not be provided this time.

=== Can I use the 2.4GHz band for non-wifi projects? ===

The following channels are available for adhoc/mesh/other wireless stuff:

* 2.4GHz: Channel 1
* 5GHz: Channel 136, 140

We cannot force you to use these channels, but we are trying to build a functional wireless network for the other attendees too. So please, don't do any experiments on other channels.

=== Can I bring an access point? ===

No, this is strictly prohibited! We need all available channels to provide good quality coverage for the rest of the attendees. Please do not be selfish here as you will degrade performance for everyone else, and we WILL track you down.

If you think you can ignore this rule because one little access point can't hurt anyone, think again. This page has the calculations on just how huge a problem it is for an event of our size: [[Network/Rogue Access Points]].

If you are operating a village (using an EMF-supplied tent) that has poor coverage, we may be able to arrange to put an extra access point in it during the event to improve coverage. Stop by the NOC and ask.

=== Can I bring a switch? ===

Yes, but for stability purposes all edge ports are limited to 10 MAC addresses at a time. If you want to connect a switch with more stations, you need to stop by the NOC and ask us to raise the port-security on your port. If you do this, you need to convince us that you know what you're doing and promise not to do anything that may harm the network - in particular, you must not connect the switch to our network by more than 1 cable (not even to a different DK). Make sure that you disable STP and other protocols on your switch which try to be intelligent.

=== My port goes up and down every couple of minutes ===

You have probably tripped port security. Most likely scenario is that you have connected more than 10 stations without consulting us (see answer to previous question). To reduce support calls, the port will automatically be re-enabled after a few minutes. But if you haven't fixed the problem, it will immediately be shut down again.

=== App ===
You can use our Android App to configure the correct WiFi settings on your Android device. Download it here:

* From Google Playstore: https://play.google.com/store/apps/details?id=nl.eventinfra.wifisetup
* Source-code: https://github.com/EventInfra/wifisetup
* APK download: https://eventinfra.org/emfcamp/app-release.apk

=== Manually ===
If you don't want to use the app, download the [https://letsencrypt.org/certs/isrgrootx1.pem ISRG Root X1], and [https://support.google.com/pixelphone/answer/2844832 install it] into your device's '''Wi-Fi certificate''' store, giving it any name you like. Then connect to the '''emfcamp''' network using the following information:

{|
| EAP method || TTLS
|-
| Phase 2 authentication || PAP
|-
| CA certificate || ''(your name for the ISRG Root X1)''
|-
| Domain || radius.emf.camp
|-
| Identity || emf
|-
| Password || emf
|}

It's fine to leave '''Online Certificate status''' as "Do not validate", and leave the '''Anonymous identity''' blank.

Network/Rogue Access Points

2022-01-16T00:43:38Z

Ms7821: Copy content from 2020

= Policy =

The Electromagnetic Field NOC operates a strict policy prohibiting the use of rogue access points.

A rogue access point is defined as any device operating in the 2.4 GHz or 5 GHz spectrums, in any mode other than 802.11 client mode, that is operated by anyone other than the Electromagnetic Field NOC.

This includes access points, phones running Wifi tethering, laptops in ad-hoc (peer to peer) mode, and any other device interfering with the 2.4 GHz or 5 GHz spectrum without approval from the NOC.

Rogue access points are not a trivial affair, and we take the problem seriously. Every beacon transmitted consumes airtime '''significantly''' affects everyone around it. With 1,700 people densely packed and using an average of 2 wifi devices each, we cannot afford the loss of any airtime, let alone the enormous amount consumed by low data rate beacons.

= How big is the problem really? =

Substantial. And if you don't believe us, here are the calculations.

Assumptions:
* Beacons are transmitted at the default interval of 102.4 milliseconds.
* Rogue AP beacons are (probably) transmitted at the lowest data rate (1 Mbps) and 802.11b long preamble is used.
* Beacons are 380 bytes without preamble.
* EMF NOC transmits 4 beacons for the 4 SSIDs we operate; 18 Mbps beacon-rate in 2.4GHz (802.11g) and 12 Mbps beacon-rate in 5GHz (802.11a).
* On average there will be 3 EMF APs within range on the same channel (at least on 2.4GHz).
* For mathematical simplicity, we assume that there are no collisions (this is unlikely, so this calculation is the ''best case'').

Each beacon is transmitted every 102.4 milliseconds and is therefore transmitted 9.765625 times per second.

Long preamble is 144 bits and the PLCP header is 64 bits.
Beacons of 380 bytes are 3040 further bits.
Total size of a beacon frame is therefore 3248 bits.
Each beacon is transmitted 9.765625 times per second so 31718.75 bits per second per beacon.

EMF transmits 4 beacons and there are an average of 3 APs in range on each channel. So 380625 bps are consumed by EMF beacons. At beacon-rate of 1 Mbps, this consumes 380.625 ms per second. However, in 2.4GHz EMF uses a beacon-rate of 18 Mbps, so it will consume 21.15 ms per second.

This means 97.89% of airtime is available for user data.

A single rogue access point added to the above equation causes the following changes:

An additional beacon of 3248 bits transmitted 9.765625 times per second.
Another 31718.75 bits per second at 1 Mbps is therefore consumed, so 31.71875 ms of airtime is used per second.

The proportion airtime available for user data falls to 94.71%

Compared to the rogue access point not being present, the available bandwidth drops to 94.71 / 97.89 = 96.75%

The bottom line is obvious: '''every single rogue access point reduces the speed of everyone around it by about 4%'''.

= I won't really be transmitting much data, it won't affect anyone =

Irrelevant. It doesn't matter how much you use the rogue access point or even if you use it at all. Just having turned on means it's transmitting beacons and consuming airtime.

= How about if I have a hidden SSID? =

Irrelevant. You will still be transmitting beacons, the only difference is that the SSID field will be null. This is not a solution, it does not offer any improvement. Hidden SSIDs are not allowed. And we can find you just as easily with a hidden SSID, as you still transmit beacons.

= I'm in a far-flung corner of the field, nobody will see it =

Irrelevant. If any of our APs can see yours, they'll back off when they see your beacon and/or will collide with it and the airtime will still be wasted.

= How about if I increase my beacon interval/rate? =

Adjusting the beacon-interval would improve it somewhat, but not significantly. Increasing the beacon-rate does however improve it greatly.

Still, rogue access points are not allowed, irrespective of the beacon interval or data rate. Besides, most consumer access points do not offer any ability to alter the beacon interval/rate.

= How do you find rogue access points? =

A proportion of our access points run in monitor mode, monitoring the air quality around them. When they detect an unauthorised beacon, they raise an alert, and triangulation between monitor APs give us an exact location to within a few metres.

If there are not enough monitors in a location to triangulate, we fall back to a laptop and an antenna on a stick.

Failing that, we will shut off power to your area until you come forward or a neighbour rats you out.

= What will you do if you find a rogue access point? =

First, '''please''' don't put us in this situation; it is unpleasant for all involved, and we'd rather spend our time enjoying the event than being authoritarian.

In the first instance, we will inform you that running your own access point is not permitted and point you to this page to explain why. We hope that you will quickly turn it off and not argue.

If you refuse to turn it off or we later find that it has been turned on again, we will employ sanctions up to and including ejecting you from the site in accordance with the [https://www.emfcamp.org/pay/terms terms and conditions] to which you agreed when purchasing a ticket.

Electromagnetic Field 2022 will be held at [[Location|Eastnor Castle Deer Park]], located just east of Ledbury, Herefordshire. This is same site that we used in 2018.

== Public transport ==

=== Train 🚂 ===
We are close to '''Ledbury''' station which is around [https://traintimes.org.uk/londonpaddington/ledbury/ three hours] direct from London Paddington (on [https://www.gwr.com/ GWR]) and [https://traintimes.org.uk/birminghamnewstreet/ledbury/ one hour] from Birmingham New Street (on [https://www.westmidlandsrailway.co.uk/ West Midlands Railway]).

Trains are likely to be significantly cheaper is you book an Advance ticket (although these tickets can only be used on the exact train booked).

=== Shuttle Bus 🚌===

We will be running a free shuttle bus service between Ledbury station and the site. Details of this are still TBC.

=== Air ✈️ ===

The closest major airport is [https://en.wikipedia.org/wiki/Birmingham_Airport Birmingham ✈(BHX)], which is around [https://traintimes.org.uk/birminghaminternational/ledbury/ 1hr40] by train to Ledbury station; or an hour by road.

[https://en.wikipedia.org/wiki/Bristol_Airport Bristol ✈(BRS)] and [https://en.wikipedia.org/wiki/Cardiff_Airport Cardiff ✈(CWL)] are around 1hr40 by road, but poorly connected by public transport.

For those travelling long-haul, BHX is likely to be be most useful followed by LHR.

== Driving 🚗 ==

If you plan to drive, you will need to buy a parking ticket (£18) or campervan ticket (£45) available [https://www.emfcamp.org/tickets/other here]. Motorcycles do not require a parking ticket. In an attempt to reduce harmful emissions, please consider [[Location/Lift sharing|carpooling]] instead of utilising your own car.

The site is around 13 mins drive from the M50 Junction 2.

Plan your travel to the south gate (adjacent to A438) - postcode '''HR8 1RQ''' should get you there. The entrance to the site is '''52°01'56"N 2°23'01"W''' / '''OS Grid SO 738 372'''.

Once you leave the motorway, follow the yellow AA signs to EMF, ignoring your sat nav which may try to take you through the town.

__NOEDITSECTION__

==General==

===Who are you?===
Electromagnetic Field is a non-profit event run entirely by a group of dedicated volunteers. EMF 2022 is the fifth major festival we've held in the UK, and a lot of us also help run other festivals in Germany and the Netherlands.

===Can I help out?===
EMF is organised entirely by volunteers. The event's success relies on attendees helping out to the extent they are willing.

More information on helping out during the event will appear on the [[Volunteering]] page in due course. If you are able to help plan and work before the event, check out the [[Teams]] page to see which teams need help.

===How accessible is EMF?===
We take accessibility very seriously, and we want to let as many people experience the fun of EMF. However, it is ultimately an event in the field, and we can't work miracles with our limited budget.

The site will be well-lit during the event, and we will aim to cover access to the stages with trackway. Travelling between stages may take some time. There will be accessible toilets and the current plan includes an accessible shower with a wheelchair ramp. We cannot guarantee 24/7 power, so it must not be relied on for medical needs, but the power infrastructure team will be on call through the night.

If you will be attending with a carer, they are entitled to a free ticket. Please [mailto:tickets@emfcamp.org email us] once you've got your ticket so we can allocate your carer a ticket. Registered assistance dogs will be allowed.

If you have any other accessibility concerns, please [mailto:accessibility@emfcamp.org drop us an email].

===Is EMF family-friendly?===
Yes! We want EMF to be a great event for hackers of all ages.

We will have free childcare provided by the award-winning [https://www.nipperbout.com/ Nipperbout], which was exceedingly well-received in 2014, 2016 and 2018. You don’t need to register in advance for childcare, just turn up. There will be a designated family camping area, and a whole track of events and workshops for young people.

EMF has a comprehensive lost-child policy with DBS-checked staff available to help out.

There are a number of things to bear in mind:
* Children under the age of 14 must be accompanied by an adult at all times.
* There will be dangerous things on site, but they will be clearly marked.
* Licensed alcohol sales are only for people of age 18 and over. Bar staff will ask for ID.

===How old do you have to be to attend EMF by yourself?===
You need to be 16 or over on August 30th, 2018 to attend EMF without an adult.

==Ticket Sales==
===What does the ticket price include?===
The ticket price includes admission to the event, admission to all of the talks, and most of the workshops. Some workshop organisers charge a fee in order to cover material costs, and places on most workshops will be limited.

Your ticket also includes:
* Tent pitch
* Water
* Showers & Toilets
* [[Network|Fast internet]]
* Electricity

===Can I bring a caravan/camper van?===
Yes, we will have a dedicated camper van area on site, within the main fence, with 16A power provided. You'll need to buy an additional camper van ticket.

If you are coming with a caravan, parking for your towing car in the car park is included.

Please try to arrive before midday on Friday and leave after midday on Monday to reduce traffic movements on site. If you're planning on leaving earlier, please let us know when you arrive so we can park you close to the exit.

We unfortunately can't provide water hookups or drainage/emptying facilities. You will not be able to empty your tank during the event.

===If I tow a caravan with a campervan, will I need a ticket for each?===

Yes.

(Somehow this is actually a frequently asked question!)

===Do volunteers get a free ticket?===
Everyone who attends is expected to buy a ticket, including the founders and the core organisation team. So many people contribute to running EMF that it would be financially impossible to give everyone who helps out a free ticket, and unfair to draw a line past which volunteers receive free tickets.

The sole exception to this rule are first aiders, who must be trained to the high standards of our first aid team, and are expected to carry out three eight-hour shifts in return for a free ticket.

===The transaction reference you've provided isn't accepted by my bank!===
If you are having trouble entering the transaction reference into your online banking, just remove the hyphen. Some banks don't like it and don't tell you why.

===Can I transfer tickets to someone else?===

Yes - once you've bought a ticket you can transfer it to someone else by entering their email address on our site. We recommend you do this if you're buying tickets for other people, so that they can receive updates directly from us.

We would kindly request that you don't sell tickets to other people for more than the price you paid for them.

You can find people who may be interested in getting your ticket at [[Ticket_Exchange]].

===Can I get a refund?===

We may consider issuing refunds to those who can't attend if the event sells out. We will not issue refunds for any reason before then. (However, you can sell your ticket on to someone else - see above.)

===Why do you sell tickets in such annoyingly small batches?===

Because we don't want to take more of your money than necessary.

EMF is a non-profit, and we aim to end the event with enough surplus to let us comfortably run the next event, but not too much more. The budget for EMF isn't solid until about six months prior to the event (especially when we've moved to a new site) but we need cash earlier in order to pay deposits to key suppliers. These secure important things like toilets, temporary structures, and the site itself.

If we were to put all of our tickets on sale early, we would have to set ticket prices higher in order to make provision for potential budget changes. By selling smaller batches earlier, we ensure everyone's ticket is the best value, and that as many people as possible can have the chance to attend EMF.

===Why have I received one barcoded ticket for x people?===
This is intended, when scanned on the gate the number of tickets used and unused for that barcode will be shown. For people arriving separately, you can either send them a copy of the PDF for use on the gate, or use the transfer tickets option (''preferred'') on the [https://www.emfcamp.org/account/purchases My Account] section of the website to transfer tickets to other people. Doing so will also allow them to receive EMF email communications and use website features that require authentication such as volunteering, customising your event schedule, or adding village/side events to the festival schedule.

==Planning your Attendance==
===Where is it?===
The EMF site is Eastnor Castle Deer Park, located just east of Ledbury, Herefordshire.

===How can I get there?===
See [[Travel]] for more details

=== Can someone take me there? ===

See the [[Travel#Carpooling]] section of the [[Travel]] page

===When can I arrive? When do I have to leave by?===
The site will open to ticket holders on Thursday at 4pm. All ticket holders must leave the site by noon (12pm) on Monday. Talks and workshops won't start until after midday on the Friday so there's plenty of time to arrive on Friday morning.

We will be there before and afterwards setting up and packing up. If you want to help with this, please let us know (by emailing [mailto:[email address removed] [email address removed]]) and we'll let you know when you can turn up. If we have not confirmed that we're expecting you before or after the event you will not be admitted to the site. '''Anyone arriving before Friday morning or staying beyond Monday afternoon will be expected to help with set-up and tear-down (both of which are mostly manual labour).''' Fewer facilities (eg, no food outlets) will be available on site prior to Friday.

===Can I turn up early to help with Build Up?===
No you may not. We already have a full allocation for build up. Due to insurance reasons, and not having enough basic facilities and food, unless you are part of the main Orga team, or have been authorised by a Team Lead, you will be not be let into the site until Thursday 4pm.

===When do things kick off?===
The talks and workshops will begin after lunch on Friday, although people will be setting up earlier in the day.

Talks and workshops run daily through to the evening, although we expect villages will be doing things late into the night! The last talks will finish on Sunday evening by 9pm.

===Can I camp in the campervan area?===

No.

People with campervans can pitch an awning or small tent beside their vehicle but to comply with fire and safety regulations we can't allow people to set up camp there.

If you have friends in the campervan area we suggest you camp in areas G or F which are adjacent.

===What's the mobile phone coverage like?===

Mobile phone (a.k.a. cellphone) coverage is almost non-existent. Of all the carriers, Vodafone seems to be the best, with some signal in some areas - but with 2,500 more people on site there are no guarantees it will work at all.

Basically, you should expect to have no reception across most of the site and most of the time.

For data, that's no problem thanks to the [[Network|excellent WiFi]] across the site. If you need to be reachable by phone during the event, your best options are:

* Use a SIP/VoIP app on your smartphone over the wifi.
* Bring a DECT phone to connect to the [[DECT|DECT network]]. There will hopefully be a way to get yourself an external phone number to your DECT phone or for outside callers to dial an extension number to reach you.
* Some networks, such as Three Mobile, support WiFi calling. This often requires activating in an area with mobile phone coverage, so it’s worth doing this before arriving.

===Will there be a bar?===
Yes, we'll be running a volunteer-staffed licensed bar selling beer and wine, as well as soft drinks and the hacker energy drink Club Mate. Far from the usual crap festival beer, we will be serving real ale from local breweries with all profits going towards making the next iteration of Electromagnetic Field more awesome.

The bar will be open 11am-2am Friday-Saturday, 11am-1am Sunday. Closing times may be earlier subject to demand and volunteer availability.

===Can I bring pets?===
Sorry, animals (except registered assistance animals) are not allowed.

===Can I smoke?===
Smoking (including vaping) is not allowed in any of the event tents or in the food/bar area. Elsewhere, please be considerate and very careful to extinguish your cigarettes to avoid setting the dry grass on fire. Please make sure cigarette butts are disposed of in rubbish bins rather than just thrown on the ground as the site is used by livestock at other times of the year, and it's a pain for the clean up crew to pick them up after the camp is over!

===Can I bring X/Y/Z?===
tl;dr Probably

Please let us know if it's going to be large/tall/use a lot of power/be noisy or anything else you think we should know. We don't want to stop people bringing the latest cool laser helmet for shark 3D printer arduino-powered UAV thing, but we need to plan for it.

Things requiring special permission and may not be allowed: balloons, sky lanterns and the like.

===Can I bring/fly my drone?===
Yes - lots of attendees will be bringing drones and there will be a dedicated UAV flying field. It is against UK law to fly drones over the campsite unless you hold permission from the UK Civil Aviation Authority. EMF will be enforcing this rule, and for safety we will not allow UAVs to be flown over the site without prior arrangement.

===What power connectors will be available?===
Mostly 16A IEC309 ('Ceeform'/'Caravan') connectors although there will be some 13A UK sockets. See the [[Power|power page]] for more information.

===What if I don't like camping?===
Whilst we'd strongly recommend camping (so much happens late into the evening and it's a lot more fun) we realise not everyone wants to. There are several hotels in Ledbury.

===What food will be available?===
There will be several food vendors on site, and volunteers will receive an excellent meal good by our caterers for each volunteer shift they complete.

===Do I need to bring cash?===
The bar will take cards, and offer cashback on purchases, but there will be no cashpoints on site. We don't know whether the food vendors will take cards, and some villages will also be running paid-for workshops where you shouldn't expect to be able to pay by card.

===What are villages?===
[[Villages]] are areas of the campsite self-organised by attendees. The idea is that like-minded people get together, set up in an area of the campsite and enjoy each other's company. Villages are often set up around a topic or existing group (e.g. lock-picking or a hackspace). Some of them will run their own events parallel to the main schedule (for example last year one village hosted a weekend-long LAN party whilst another ran workshops on ring-making).

If you want to find out more, or see which villages are already proposed see the [[Villages| villages page]]

You don't need to join a village to attend.

==At the Event==
===How do I connect to the wifi?===
Unless you know of a reason not to, you should connect to the emfcamp network if your device can see it, or emfcamp-legacy18 if not. You'll be prompted for a username and password - you can provide any value you like, but the following have special behaviour if you use them as both the username and password:

'''emf''' - Assigns a public IP address to your device. This will make it accessible to any user on the internet, so please take extra care to ensure your firewall is active, and operating system is up to date.

'''outboundonly''' - Allows only outbound traffic, similar to having your device on a typical coffee shop network. This will provide a bit of extra security, and potentially save battery life.

'''internetofstuff''' - Allows inbound traffic, but only from the camp network. This is specifically intended for devices you'd like to share access to with attendees, but don't want exposed to the internet at large.

If you're unable to connect to either emfcamp or emfcamp-leagcy18, or have other interesting requirements, see [[https://wiki.emfcamp.org/wiki/Network#Wireless this page]] for further details.

===Can I attach a hammock, slackline, or other things, to the trees?===
Nope. The site owners are very protective about them and have specified that we don't attach anything to them.

===Can I light a fire or BBQ?===
Yes as long as its contained and raised off of the ground so that the grass/ground arent burnt/scorched etc.

The whole field has been covered with many wireless access points to ensure the best possible coverage and to allow you to roam seamlessly without interruption. Please note that your device will be reachable by anyone on the internet, please take suitable precautions such as turning on a firewall, and making sure your software is up to date.

You should not bring your own wireless access point, its unlikely to provide better service than the camp ones, and it makes the network worse for everyone else. Any rogue access points will be hunted down and disconnected from the network - see [[Network/Rogue_Access_Points]] if you want to know why. If you have a project that needs to provide its own AP for some reason please contact the NOC.

== Wired Ethernet ==

All camping areas are within 60m of a datenklo (or data toilet), where you can connect to the network. If you intend to do so please bring 60-70m of CAT5 cable as we are unable to provide any.

Lay your own cable neatly from your tent back to the nearest Datenklo, and leave 6m of slack coiled on the floor in front of it. And please lay it so that it can be clearly seen that it needs to be plugged in - or you risk having your cable overlooked. At regular intervals a member of the NOC team will connect it up and enable the port.

Note that most of our ports will not support 10 Mbps - if you need it for old equipment or embedded things, please bring your own switch to convert.

==What should we bring?==

=== Cooking Equipment & Food ===

While EMF provides a great set of food vendors, it may be easier or cheaper for you to get together and cook. Some villages cook for upwards of 100 people each meal, but there’s no reason it can’t just be 5 people.
Think about the things you’ll need - a stove, pots & pans, plates/bowls, cutlery and food.
We’d really appreciate it if you brought reusable plates and cutlery, and low-packaging food. This helps reduce our waste footprint and helps the environment.

Learn more about onsite food [[Food|here]]

== Public/Shared Area ==

You will want somewhere to work together, to show off your toys, to run workshops and more. What you’ll need is a ‘village square’. This can be a few tables and chairs, all the way up to a geodesic dome!

With the unreliability of British weather, we recommend that this area is covered - it can get really sunny and really wet at our site. We’d rather neither you were sunburned nor your laptop flooded.

The village team would really appreciate it if you planned this ahead of the event and could tell us the area in m2, so we can layout the site and get you the best location possible!

EMF are happy for you to bring your own tents and furniture for being social in and cooking in, but you can also rent them for us for the event. We ask that you remove all tents and furniture that you’ve brought at the end of the event - it’s not fair on our volunteers to have to tidy them up, and it’s also bad for the environment.

== What makes a good neighbour? ==

A good neighbour works with those around them so everyone has the best possible event. This includes understanding the area you are camping in and compromising with those nearby! We have both quiet and noisy camping areas. If you intend to have friends over working, partying and enjoying each other’s company until the wee hours, we’d ask that you place yourself in the noisy area.

It’s great if you can share with your neighbours too - maybe you want to group 3-4 villages together into a common theme, and share resources. This could be cooking, hardware or other items. You can get in touch with your neighbours ahead of the event and see if they want to do anything with you - it could be a shared event, or helping with their cooking in exchange for food!

Villages

2022-01-16T00:27:31Z

Ms7821: Copy content from 2020

__NOTOC__ __NOEDITSECTION__

The camping areas at EMF contain a number of villages.

== What is a Village? ==
A village is a group of friends, like minded people, colleagues or even families. Maybe your village is a collection of sub villages, or maybe it’s just your hackerspace. We also see villages based around themes, shared passions and existing communities - great places in the past have been the Maths village, the HAB Village and groups like Milliways and the Scottish Consulate.

If there is a village based around something you are interested in, then you should definitely visit that village during the event to see what's going on. Or you could even join that village to help make more things go on. If there's not a village based around your interests, then you can start your own village and others will probably join you.

There is no requirement to be part of a village, so if you'd rather camp on your own and just visit some villages this is fine.

If you're planning to bring something especially big or in need of lots of power to your village, please [[Contact|let us know beforehand]] so we can provide you with what you need.

== What can we do as a Village? ==
[[File:maths-village.jpg|thumb|right|Making intersecting tetrahedra at the Maths Village in 2018]]
Villages are great as you can share ideas, equipment and space! The sharing doesn’t stop there - it lets you share resources too. You can come up with a cooking and cleaning rota as a group to reduce waste, make the camp cheaper and interrupt your day with a change of activity. Some people spend all their time cooking for others!

Maybe you are working on a group project and want to show off the final result, or you want to spend the weekend building something. Doing this as a village is good fun, and you often find that new friends will appear to share their ideas, opinions and time with you.

Some villages bring pre-made games and activities for other people to take part in, and some run events and parties during the weekend!

If you have a good space, you could run a workshop, a series of lectures or even your own mini-conference, entirely separate from our main program! Some of our favourites from previous years include:
* [https://wiki-archive.emfcamp.org/2018/w/index.php/Village:Goldsmithing Ring Making Workshop]
* [https://wiki-archive.emfcamp.org/2018/w/index.php/Village:ObscureCon Obscurecon]
* [https://wiki-archive.emfcamp.org/2018/w/index.php/Village:Hardware_Hacking_Area Hardware Hacking Village]
* Personal Introduction to FPGA programming
* [https://wiki-archive.emfcamp.org/2018/w/index.php/Village:HABville Launching High Altitude Balloons]

=== We're here to help ===

You're welcome to run events in your village. If you have a cool idea, but need help with planning or logistics of doing things on site, please contact us before hand. The earlier you let us know your plans, the better we can help you.

There is also limited funding available for villages that want to put on content. Please [mailto:villages@emfcamp.org Email the Village People] and we will be very happy to discuss anything you might come up with!

Some areas we’d love to expand are:
* Technical presentations
* Skill shares
* Workshops
* Roundtables

== Register a Village ==

Sign up with the [https://www.emfcamp.org/villages/register village registration form] on the main website!

The details you input won't be final - the form can be edited in future - if you're struggling for details, please input speculative numbers and refine them later once ticket sales are closed, or once you've discussed it with us.

You can see [https://www.emfcamp.org/villages/2022 Registered Villages] on the main website.

The Village People plan to be more involved in the placing and layout of villages this year to minimise collisions and disagreements!

We'd very much appreciate it if you could think ahead of time and consider these things the registration form asks:

* The area your village will need in m², and provide us a realistic estimate so we can place you!
** The number of attendees will influence area
** If your attendees intend to camp at your village or away from it will influence area
** Structures you plan to bring will impact how big your village is - tell us their area!
* If you want to run your own events / stage / workshops
* If you will be noisy or quiet, and what hours you'll be loud at so we can place you in quiet/noisy areas
* If you want to do anything spectacular or out the ordinary - just get in touch and we can make it happen

== Being a Good Village ==

We're compiling a guide of what makes a good village, based on our past experience!

If you want to help, add some useful advice to the [[Good Village Guide]]!

|-
| align=right |🥛|| A mini fridge may be useful for storing milk.
|}

== Things to avoid if possible ==
{|
|-
| align=right |🍾|| Glass bottles: broken glass is a pain to clean up.

|-

== Eating On Site ==

There will be food vendors on site throughout the event, although we don't yet know which ones specifically will be present, and the Robot Arms will be serving a wide range of drinks. Volunteering is rewarded with free food from our catering crew.

== Bringing Your Own Food ==

You're welcome to bring your own food and drink, but please keep in mind that all open flames must be elevated off the grass. If you need to resupply there is a [https://www.google.com/maps/place/Tesco+Superstore/@52.0412141,-2.4282916,17z/data=!4m5!3m4!1s0x48705460698b2927:0x8c7bf2537561901b!8m2!3d52.0412108!4d-2.4261029 Tesco in Ledbury]

Power

As usual, our lovely power team will provide power to all our attendees. This guide will tell you how to connect safely.

Power will predominantly be delivered via 16A (Blue IEC60309 "Ceeform") connectors although some 13A UK sockets will be available within datenklos.

We plan our campsites so that no point will be more than 40 metres away from a source of power, but the majority of power extension leads are 25m or shorter, so please aim to arrive early if you really need power, or try and connect via a neighbour.

If you're coming by yourself, bring a good-quality reel-type extension lead (ideally at least 25m) with a 13A or 16A plug. If you're coming as part of a larger village, try to bring enough equipment to safely distribute within your village.

Power requirements in excess of 16A single-phase are subject to special request - please email us as soon as possible so we can try and sort something out.

== Safety ==

The power network is designed and tested to relevant UK standards. All sockets within the camping area are protected by 30mA RCDs to reduce risk of electrical shock.

You should always make sure that any connections are kept well inside an enclosed area which won't get wet. If you suspect a connection has got wet, please disconnect it yourself or ask for a member of the power team if you don't feel you can.

If it rains, the earth leakage current from a number of slightly damp appliances can add up to enough to trip our larger upstream RCDs, which will inconvenience more people than just you - so please keep try to keep things dry!

== Camper Vans & Caravans ==

As usual, we will provide 1x 16A Ceeform socket in the campervan area for every campervan/caravan ticket sold.

== Electric Vehicles ==

We will provide power for charging electric vehicles in the parking field near the entrance.

Please note that your vehicles will be charged from our (modern, clean) diesel generators - there is still no other economical way of providing power at events like EMF - so please make sure you only charge as much as you need.

Our present plans involve providing power either on standard 16A Ceeform connectors or on UK 13A sockets. Add yourself to the [[Power/Electric_Vehicles| EV charging page]] though.

[[File:Emf1.jpg|thumb|left|The EMF sign in 2014]]

Electromagnetic Field (EMF) is a non-profit UK camping festival for those with an inquisitive mind or an interest in making things: hackers, geeks, scientists, engineers, artists, and crafters.


To get an idea what EMF 2018 was like, you can view the [https://wiki-archive.emfcamp.org/2018/w/index.php/Talks list of talks, workshops and performances] and see recordings of a number of them on our [https://www.youtube.com/user/emfcamp1/videos Youtube channel]. If you are inspired by the past content, please consider giving a talk yourself or running a workshop this year!

The campsite will also have a number of [[villages]], where those with something in common can camp together. Keep an eye on this wiki, and pick a village to join, or start your own.

At each EMF event we give our attendees a programmable badge. In 2018, attendees received a MicroPython enabled [https://blog.emfcamp.org/2018/08/26/tilda-mk4-the-emf-2018-badge/ TiLDA Mkδ]. Information about past badges including TiLDA, SiNE and our next badge can be found [https://badge.emfcamp.org here].

We recommend everyone reads the following pages before arrival:
* [[Travel]]
* [[Power]]
* [[Food]]
* [[What to bring]]

If you want to get in touch, there is info on the [[contact]] page.
