FORTIS Survey

G3T’s Tetley Scanner is an industry leader and one of the most powerful and flexible portable survey systems available. The engine behind Tetley Scanner is G3T’s FORTIS Survey, which provides the power and flexibility of a truly simultaneous, multi-band, multi-radio technology scanning solution.

Survey can simultaneously measure all active cellular technologies, including GSM, CDMA, EvDO, UMTS, LTE, 5G, LTE-M, NB-IoT, and Satellite DTC. Additionally, Survey supports PTT/D-PTT (NXDN, DMR, P25) and AIS formats.

Survey’s Sentinel mode enables it to function as a powerful wireless threat detection solution, capable of detecting the presence of jammers, IMSI grabbers, SMS blasters, interference, and unexpected changes to serving cells
