Guys i need a quick answer on this.
a WBX 50 MHz to 2.2 GHz Transceiver is sufficient enough for an USRP2
to read the full GSM spectrum ?
compared to a DBSRX 800 MHz to 2.4 GHz Receiver which one is advised to use?
do i need both ?

The DBSRX does say it can handle a 60mhz wide band, but I don't know how
accurate it would be.. And yeah, the amount of data coming back would be
insane..
Talking hypothetically here... there's no way you could decode every single
one of those data streams on the fly, at least, not without
I ordered both DBSRX and WBX to be sure
(im sure by next week after the blackhat conference these items will
run out of stock instantly)

serious cash.
You could dedicate time. You could do some preprocessing on the FPGA
(demod) to reduce the amount of data to bring back.
Surely

Silly question but, when a new tmsi is issued by the vlr, how does the
handset get told what its new TMSI is (or does it never know itself?)
New TMSI are only issue during LOCATION
I suggest to anyone interested to :
* Read the Um interface page on wikipedia
