We recommend our PKI 6750 Mobile Phone and WiFi Jammer when offices or conference rooms have to be protected from eavesdropping. Its compact design provides stationary and mobile operation. The PKI 6750 Mobile Phone and WiFi Jammer covers not only frequency for mobile phones but also 2.4GHz frequency for WiFi, Bluetooth and video transmission. Each frequency range can be controlled separately in order to achieve optimal adaptation to local networks. The PKI 6750 Mobile Phone and WiFi Jammer allows optimal tuning of transmitting power in order to restrict the operating radius to necessary premises. It is also possible to use directional antennas instead of the supplied omni-directional antennas. The operation of PKI 6750 Mobile Phone and WiFi Jammer is very easy due to its comfortable control elements.
