  • Bridging communications between tactical SDR and cellular telephone networks
    Patent number: 8996061
    Abstract: A device for bridging communications between radios on a tactical network and telephones on a public cellular network. A dock region of the device housing receives and engages a given telephone that operates on the second network. A processing core of the device has (a) a core engine for receiving and transmitting first radio frequency (RF) signals on the first network, (b) digital signal processing stages for (i) translating first information modulated on the first RF signals into a format compatible with telephones on the second network, and producing corresponding translated first information, and (ii) translating second information demodulated by the given telephone from second RF signals on the second network into a format compatible with radios on the first network, and modulating the translated second information on the first RF signals transmitted by the core engine. An adapter provides an interface between the processing core and the given telephone.
