GPRS / UMTS with OpenBSD

Contributed by deanna on from the ATZ OK dept.

In what's not even the last of the OpenCON slides, Felix Kronlage talks about Redundancy or mobile deployment with 3G technology, explaining the current and future state of UMTS and GPRS networks, how they are accessed through OpenBSD, what devices are supported, and what the future will hold. This presentation includes lots of tips on creating and improving your connection, and even more information is available on fkr's web page.

Conclusion: OpenBSD + Soekris + GSM/GPRS = Internet on the Baltic Sea!

        and there was me thinking the kite was just to lift an AP and GPRS modem...

        standard GSM timing allows 35km if you can pick up the signal, but there are extended range BTS using two timeslots which can reach approaching 120km. No clue about GPRS though.

          I work for a wireless carrier in north america. You're correct about 35km for a standard bts. Extended cell is supposedly good out to 90km but we aren't sure about gprs. One of our techs will be out in a fringe area this week to to some extended cell testing. We'll have him try gprs and if anyone is interested I will post the results here. Never got a straight answer from our vendor on if it's just Edge that won't work or gprs also.

              Just heard back from one of our RF engineers. Neither gprs or Edge worked past 33km (21 miles). Not sure if anyone is watching this thread but there you go.

              If anybody wants me to try anything else just let me know. We have GSM and UMTS.

    Is there really GSM coverage over the Baltic Sea?
    I'm serious, forget about GPRS, is there even weak GSM coverage?

      Clicking around here:
      http://www.gsmworld.com/roaming/gsminfo/index.shtml
      shows at least some parts of the baltic are covered.
