How to get there

By Public Transport

• Train:

  • Long-Distance Connections: Travel by ICE/IC to Erfurt, a central hub reachable from major cities such as Berlin or Frankfurt.

  • Regional Train to Bad Langensalza: from Erfurt in ~30 min, transfer to a regional train to Bad Langensalza.

  • Shuttle Services: We are organizing shuttles from Bad Langensalza to Sundhausen. Details will be provided soon.

• Regional Buses:

  • Local buses may connect Bad Langensalza with Sundhausen, but services may be limited. Please check schedules in advance.

By Plane

If you are flying, two major airports offer convenient options:

• Frankfurt Airport (FRA):

  • A major international hub approximately 250 km (155 miles) from Sundhausen.
  • Take an ICE/IC train to Erfurt, then transfer to a regional train for Bad Langensalza.

• Berlin Brandenburg Airport (BER):

  • Located about 300 km (186 miles) from Sundhausen, BER offers excellent international and domestic connections.
  • From BER, take a train to Erfurt via long-distance services and proceed to Bad Langensalza by regional train.

By Car

• From the North (e.g., Göttingen or Kassel):

  • Take the A38 motorway and exit toward Leinefelde-Worbis. Follow the B247 to Bad Langensalza and then local roads to Sundhausen.

• From the South (e.g., Munich):

  • Use the A71 motorway toward Sömmerda, then take the B176 and B247 to Sundhausen.

• From the East or West:

  • Use the A4 motorway, exiting near Gotha or Eisenach, and follow signs to Bad Langensalza.

Accommodation

Camping

We will have access to a campground, which can be used free of charge. There will be toilets and showers available, but electricity will be limited, so please bring a power bank if needed. It’s also possible to come with a camper van. (Pictures of the campground will be shared soon.)

Bed&Breakfast

For those preferring indoor accommodation, a few apartments are available in Sundhausen and nearby villages. The number of beds is limited, so if you're interested, please contact the Orga Team as soon as possible.

Other Options

Additionally, there is a small hotel in the next town for those looking for more comfort. Please contact the Orga Team for that, too!

Weather Conditions

In June, Sundhausen experiences mild to warm temperatures, typically ranging from 18°C to 25°C during the day. Nights can be cooler, sometimes dropping to 10°C or lower, so bringing a warm sleeping bag and extra layers is recommended. Rain is possible, with occasional short showers, so a waterproof tent, rain gear, and sturdy shoes are advisable.

Food and Drink supply

There is no supermarket in Sundhausen, and the nearest one is not within walking distance. We are currently evaluating different options to ensure everyone has access to food:

• Catering – We are looking into meal options, ranging from individual meals to full board, depending on the cost and available sponsorship.
• Mobile Grocery Store – A “rollender Supermarkt” (mobile grocery store) regularly visits the village. We are in contact with the provider to see if additional visits can be arranged during the event.

We also plan to provide non-alcoholic and alcoholic drinks, but these must be paid for by participants.

More details will follow as plans are finalized.

Registering

Add yourself to the participants list. If you'd rather not have your name there, please send an email to the organization team with the same information displayed on the participants list.

The event is free of charge and open for all.

What we do

In brief: we will have organized talks, workshops and discussion panels on community networks and wireless mesh networks (see Call for Participation). There will also be more informal activities: cooperative hacking, self-organized projects, and (we hope) delightful conversations!

Full schedule: #Talk_Schedule_and_Workshops

In addition, there may be a self-organized wireless mesh network, running different routing protocols to compare them. Please coordinate directly on the battlemesh mailing list to make that happen.

Call for participation

We invite participants to propose workshops, talks, or panel discussions related to network infrastructure in general: how it can be built and operated as a common good, and how to sustain a community around networking.

We welcome contributions that broadly address these questions from various perspectives: technical, organisational, economical, regulatory, juridical, or political. Example topics:

• 🌍 Wireless Community Networks
• 🏡 Community Networks that deploy Fiber-to-the-Home (FTTH) networks
• 🛠️ Free hardware and free software for Community Networks
• 🤝 How to organize a durable community structure?
• 🧑‍🤝‍🧑 How to involve non-technical people? To "digital stewardship" and beyond?
• 📢 How to disseminate the spirit of community networks, knowledge, etc.?
• 🌾 Connecting rural areas: challenges and solutions
• 🚀 How to take advantage of a community network in ways otherwise not possible? What are the applications?
• 🔗 Local Internet Exchange Points (IXPs) as a common infrastructure
• 🌐 DNS as a common infrastructure?
