High Power Cellular Blocker

The systems utilize a unique transmission method that confuses the decoding circuits of cellular handsets as if no cellular base station is within the service area. Upon activating the Blocker,  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 routed into a voice mailbox.  When the Blocker  is turned off,  all cellular handsets will automatically re-establish communications with the cellular systems and provide full service.

This high power unit is Custom Made per order.  It can contain up to three system modules, each having a maximum output power of 10W (total 30W). The unit is housed inside a metal water resistant suitcase with a built-in heat sink to meet extreme operating conditions for indoors and outdoors applications. The unit can be locked so that only authorized personnel can open it. Unit activation/de-activation by turning a key switch - suitable for secure installations.
