Probably meant transmitter (antennae + encoder/decoder) separated from actual BTS hardware & operatives. So after counter-side finds your camouflaged BTS, it is only disposable and relatively cheap part and doesn’t lead to whole operation uncover. That probe part then would connect to starbucks wi-fi and interact with BTS software somewhere far from physical location, so you can’t quickly trace channel between probe and spy team.
