But they would have to be experts in GSM signalling. And those experts tend to have better things to do. Also, a laptop and a antenna would not suffice, software-defined radio would be required and currently there is no SDR design on market with sufficient performance.
If the unwashed masses suddenly gain access to such capabilities effortlessly then it would be a concern. Presently it is not, because smart phones have GSM subsystems carefully separated and ‘dumb’ phones have certain limitations built in. Behaving graciously is assumed a mobile station's role in the GSM system.
Recall the Nokia 1100 rumor eariler this year where underground allegedly gained acces to frimware memory map of certain series of this phone and its price skyrocketed on second hand market.

- slackenerny 17y agoIt can't be a tower, at most a sort of bridge and barely at that. Harald Welte's OpenBSC is more advanced http://bs11-abis.gnumonks.org/trac/ http://bs11-abis.gnumonks.org/trac/. It is built on Siemends industrial design and not USRP as the BTS.
- wmf 17y agoIt doesn't surprise me that OpenBSC is more advanced given that my understanding is that the Siemens hardware does a lot of the hard work. OpenBTS is more impressive (and more customizable for evil) since it has to do everything in software.
