You absolutely could build a stingray with an SDR with OpenBTS, although I'm not sure how you'd get it to emulate 4G. As far as I know, OpenBTS only supports 3G

For the lazy, a 3G tower dev kit from Range Networks is $8,000 [1].

- bjornsing 7y agoAFAIK stingrays typically use 2G, since 3G and upwards have strong mutual authentication (i.e. the network authenticates the phone but the phone also authenticates the network). They just jam the 3/4G signal to make the target phone fall back to 2G.
- Fnoord 7y agoAgreed. I've never done it, but I suppose you could use 2 SDRs. One for setting up OpenBTS, one for jamming 4G/LTE.
