Purpose: GSM/UMTS Selective Jamming

General Info: Cellular Firewall has been designed for selective blocking of GSM/UMTS communications. Based on the Active BTS infrastructure, Cellular Firewall allows authorized GSM/UMTS mobile subscribers to use their mobile devices as usual, initiate or receive calls, send text messages, etc., while still being in the vicinity of the system; at the same time unauthorized phones are denied of cellular services. Cellular Firewall is available in various configurations to suit various conditions and match the requirements of every customer.

Selective Blocking of GSM Phones

Cellular Firewall enables to define the designated list of GSM/UMTS phones. When operated, the system blocks all phones in the list of unauthorized MS/UE, while allowing authorized phones to continue functioning normally. This makes Cellular Firewall an ideal solution for prisons and jailing facilities, preventing inmates from unsupervised communications with the world outside the prison walls, and at the same time allowing the prison staff to continue using their GSM/UMTS phones as usual. The solution can also work in strategic installations such as power plants, ports, etc., and is suitable for tactical situations (such as hostages’ scenarios).

GSM and UMTS Bands, Various Configurations

Cellular Firewall is available in several configurations: fixed, vehicle-mounted or carry-on. While fixed or vehicle mounted installations can be fed from an external power source, the carried unit performs for hours using a set of internal batteries that can be recharged or replaced when needed. The unit can be easily packed in standard bags or suitcases or mounted on a vehicle to allow covert operation in populated areas. Cellular Firewall supports up to 4 GSM bands (850, 900, 1800, 1900), making it applicable to any location worldwide that features an operating GSM network. The 3G module supports up to 5 UMTS bands (2100, 1900, 1700, 900, 850).
