Cellular Jammers are special devices designed for the purpose of jamming cellular calls in restricted areas.The range of jamming depends on their output power and the distance from the nearest cellular cell antenna.
In several cases there is a problem to jam the required area without causing interference to nearby areas. In order to perform such delicate jamming, there is a need to use several jammers with relatively low output, and sometimes to use directional antennas, to achieve cover of asymmetric area, while understanding the limits of buildings and topography, as well as operating sophisticated test equipment .
The area coverage depends on several factors, which are detailed in the figures attached to the specifications.
Basically , a cellular jammer , is an electronic warfare device , competing with the transmission coming from the nearest cell base. 

Wireless Avionics completed, successfully, a number of complicated installations in high security zones, while meeting the coverage requirements without creating interference to the neighboring areas.

Our self-manufacturing jammers, combined with comprehensive experience and sophisticated instruments, are the necessary key for successful implementation.
