Intro
ST-TG101B is a “Cellular Firewall” that effectively blocks all cellular transmissions within a given area. As a jamming device, it transmits low power radio signals which cut-off communications between cellular hand sets and base stations. The jamming effect can be digitally controlled to form quiet zones that accommodate every security need. C-Guard does not interfere with any communications other than cellular within the quiet zone and does not interfere with cellular communications outside the regulated area.
Method of Operation
The system utilizes a unique transmission method that confuses the decoding circuits of cellular hand sets as if no cellular base station is within the services area. Upon activation, all idle phones will indicate “NO SERVICE.” Consequently, all cellular phone calls already in progress within the defined area will be cut off and the radio link will be lost. When activated, incoming calls are handled as if the cellular handset is off and calls may be rerouted to a voice mailbox. When deactivated all services resumes.
The Medium Power unit contains four modules, each covering a single frequency band (800/900/1800/1900). The unit is microprocessor controlled and has digital power control allowing for accurate calibration of transmission power. Each module has an external antenna and maximum output power of 10 W per module (total 40 W).
Various optional accessories are available including rechargeable battery pack and remote control. The unit is housed inside a metal frame with a built-in heat sink to meet extreme operating conditions for indoor or outdoor applications. The unit can then be integrated within a Pelican waterproof case. The unit is activated manually or by remote control.
