RE: GPRS, EDGE support

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.

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.
