SENTRY is a strictly passive receiver, performing network survey, tuning to channels of interest, and collecting cellular data. The receiver houses all of the data until offloaded or retrieved by the user or by automated analytics systems. With 7TB of storage the receiver can capture millions of data records which allows for long term remote or unattended data collection. SENTRY provides coverage from 75MHz to 6GHz with the 6 x 200MHz tuner configuration, covering multiple bands (up to 11) simultaneously throughout the spectrum.

Wireless technologies include GSM, CDMA, UMTS, and LTE (5G in 2024). SENTRY monitors and decodes Uplink (UL) and Downlink (DL) messages simultaneously, providing for soft geo-location of user equipment. One or more SENTRY receivers can be networked together to provide more precise location measurements. G3T receivers (SENTRY/SPOTTER) are interoperable and interchangeable within the G3T Collection & Analytics ecosystem.
Additionally, adding G3T’s Active network Characterization tools (HYDRA/TETLEY HANDY) enables more refined UE location.
