Osmocom Developer Conference 2018

Contrary to OsmoCon2018, the Osmocom Developer Conference 2018 (OsmoDevCon2018) is an event by project members for project members.
As such, the primary audience is people who have been contributing to at least one of the Osmocom projects.

It is not targeted at users.

Attendance requires registration (see below) and notification of acceptance. The number of participants is limited to about 20.


April 20-23rd, 2018

Time: We will start at 10am in the morning, will take lunch break from 1pm to 3pm and have an open
end at night. We have a key to IN-Berlin to come and go as we please.


In the rooms of IN-Berlin e.V., Lehrter Str. 53, 10557 Berlin, Germany, the Universe. (Map)

The meeting / seminar / conference room at IN-Berlin is located on ground floor and has windows facing east.
In front of those windows is a road + sidewalk which is directly in north-south direction,
i.e. it may be possible to set up some (GPS, Thuraya, etc.) antennas on the sidewalk, if required.
Some kind of pole+stand is required, though.


The format of this workshop is not primarily formal lectures/talks. It's more like "guided discussions", i.e. there are topics and each topic will get an "owner" who should introduce the topic and lead the discussion related to it.

Avoiding dehydration during the day

IN-Berlin has a fridge with a selection of cold beverages (lemonades, club mate, water, beers) available to be purchased at extremely low prices (about 1 EUR / bottle). There are tea and coffee-making facilities. They also carry some candy-bar type snacks. There are several supermarkets within walking distance from the venue, if you'd like to bring your own.


This year we'll have light lunches (sandwiches, salads, cold cuts) brought to IN-Berlin every day. Cooked food will be served only for dinner. Exception is the final day (Monday).

Dinner catering will be brought into IN-Berlin every night. Sponsoring is TBD.

Travel funding is currently not yet available from any sponsor.


Berlin still has two active airports during OsmoDevCon2018: Tegel (TXL) and Schoenefeld (SXF). TXL is closer to the venue.


You can take long distance trains to Berlin Hauptbahnhof (main station), which is only 15mins walking (or 3 bus stops) from the venue.

Public Transport

Check for maps, fares, etc.


There is some public parking in Lehrter Str., where IN-Berlin is located, but it is quite crowded. Parking your car might
not be easy.


Berlin has tons of options, from very cheap to plush and expensive. Pick your favorite.

The closest low-end option in walking distance (about 7 mins) is the A&O Hostel Berlin-Hauptbahnhof.

A more expensive alternative within 15 minutes of walking is Motel One Berlin-Hauptbahnhof
