Bridging communications between tactical SDR and cellular telephone networks

摘要

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.

1. A device for bridging communications between radios operating on a first wireless network, and telephones operating on a second wireless network, comprising:
a housing including a dock region dimensioned and arranged for receiving a given telephone configured to operate on the second wireless network, and for retaining the telephone at an operating position in the dock region; a processing core contained in the housing and including (a) a core engine operative to receive and to transmit first radio frequency (RF) signals on the first wireless network wherein information is modulated on the first RF signals with a defined waveform in a first format, (b) one or more programmable digital signal processing (DSP) stages configured for (i) translating first information modulated on the first RF signals in the first format into a second format compatible with telephones operating on the second wireless network including the given telephone, and producing corresponding translated first information, (ii) translating second information demodulated by the given telephone from second RF signals on the second wireless network into the first format to be compatible with radios operating on the first wireless network, and (iii) modulating the translated second information on the first RF signals transmitted by the core engine with the defined waveform in the first format; and an adapter associated with the housing and constructed and arranged to provide an interface for sending the first translated information from the processing core to the given telephone, and for sending the second information demodulated by the given telephone to the processing core, when the given telephone is set at the operating position in the dock region of the housing; wherein the core engine of the processing core is programmed and configured to receive and to transmit the first RF signals on the first wireless network in the form of software defined radio (SDR) waveforms; and the SDR waveforms include waveforms defined by the Joint Tactical Radio System (JTRS).
