Rapaport, Distributed Real-time Signal Processing for Cellular and Paging Traffic Analysis, Fraud Detection, and Intelligent Wireless Network Control, 43rd IEEE Vehicular Technology Conference, May 18-20, 1993. [This paper describes devices for recieving and analyzing cellular telephone and pager signals. Capabilities include real-time signal strength measurement, spectrum analysis, demodulation, and decoding. With these capabilities, patterns can be associated with particular cellular instruments and used to discriminate against cloned phones used for fraudulent purposes.]
