RE: Re[2]: GPRS, EDGE support
OpenBTS supports GPRS, but at least for me it does not work very reliably, I consider this only a proof of concept. While voice/SMS range is up to 200m, GPRS breaks down after 5m (!) distance, and the connection stalls after a while, requiring a restart of OpenBTS. I am using an USRP1 with WBX board. Ralph.

THe problem with nanobts that it is unaccessible, and even when it turns up on ebay, it costs a fortune. I'd rather pay that fortune for an USRP or half that fortune for a bladerf, and I will have an SDR which I can use not only as a BTS. So, at the moment GPRS/EDGE is only possible with nanoBTS? What about USRP or BladeRF running OpenBTS? BR, Csaba There has been a working GPRS stack for a while now: http://openbsc.osmocom.org/trac/wiki/OpenBSC_GPRS As for USRP or OpenBTS, I cannot comment upon having never used either platform.
Ralph - I realize this is off topic, but if you have such severe range differences between CS and PS performance, it is probably a GPRS uplink power control configuration problem. Note: I am no longer affiliated with Range Networks, just trying to be helpful. — David On Jan 23, 2014, at 20:12, Ralph A. Schmid, dk5ras <ralph@schmid.xxx> wrote:

Yes, this also is my idea, but configuration of this is somehow difficult, and I do not get clear, reliable results from changing the parameters. I have noticed that you're not a "Ranger" anymore; hopefully your broad knowledge is still available for the GSM world :) Ralph. From: David A.
