> did anyone allready had the chance to have a look at the magicjack > femtocell ? hi, not really. the homepage www.magicjack.com shows something, but does not say anything about GSM or femtocell. products at ebay called "magicjack", look like a simple POTS interface for VOIP, not a BTS. but if someone knows where to get this femtocell, it please let us know. andreas

power amplifier for DCS 1800
by Konrad Meier 11 Sep '10

11 Sep '10

Hi, I am building a GSM Test-Network at the university of Freiburg (Germany). We have a license for some channels in the DCS1800 band. For the network we are using nanoBTS and we would like to amplify the TX Signal from the nanoBTS. Does anyone know a suitable power amplifier? The output signal from the amplifier should be 1 or 2 Watt? Regards Konrad

ULP [was: Problem connecting to NanoBTS with current version of OpenBSC]

Hello Andreas, On Tue, 07 Sep 2010 13:57:56 +0200, "Andreas Schmidt-Dannert" <aschmida(a)mail.tu-berlin.de> wrote: > > I can only see the DNS query for the ip of the SUPL server and than some > TCP packets going to the SUPL port (7275) and back to my mobile phone. I could just verify my assumption: The traffic is SSL encrypted. If you tell WireShark to decode the trace as SSL you can see that the result will make sense. So I guess that the ULP traffic is embedded in SSL. I found a valid ULP trace here: http://pastebin.com/6vfri6Mt I don't know from whom it is, it is already decoded.

I don't know whats wrong with your configuration, I can just say that here switching between different PCs running OpenBSC works without problems when the correct OML IP address has been configured for the nanoBTS ("-o" option of "ipaccess-config") and the nanoBTS was restarted. I am interested in what you want do try with RRLP because I recently did some more experiments with it. Especially I would like to try "MS-assisted" position measurements next, however this method requires the acquisition assitance data which have to be calculated first, I don't think they can be extracted from the data of a GPS receiver. I don't know if there is some ready and tested code for this already available which would make it easier to get this up an running.
