Osmocom Developer Conference 2013

Ths Osmocom Developer Conference 2013 (OsmoDevCon2013) is an event by project members for project members.
As such, the primary audience is people who have been contributing to the project.

It is not targetted at users.

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


April 4 through April 7, 2013. This is Thursday through Sunday, to ensure people with regular day jobs
don't have to take off four but only two days.

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.

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 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.


Lunch catering will be brought into IN-Berlin every day. Sponsoring for this will be provided by sysmocom GmbH.

Thursday Baecker Schnell Cold cuts, Salad, Pastries
Friday Indian (Aapka) Eggplant with almonds and cashew nuts in mild sauce, grilled chicken in butter tomato sauce and mutton with fresh champignons, basmati rice, bhatura & naan bread
Saturday Seerose Vegetarian buffet, TBD
Sunday ? TBD, most likely traaditional german food with lots of meat (sorry Andreas)


Last year there were some complaints that dinner was not organized. Even if there is no sponsoring, it would have been useful to
at least have some reservations. We will take this recommendation and organize something.

Day Type of food Where (from/to)
Thursday Pizza Pizza delivery 50m from IN-Berlin
Friday Sandwiches or Restaurant ?
Saturday Sandwiches or Restaurant ?



Berlin has two active airports during OsmoDevCon2013: 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, but not as bad as at C-Base last year.


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

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

Spectrum License

We have ARFCN 874 and 877 from the 1st to the 15th. BNetzA has been super speedy. Paid by sysmocom.
