Patent ID: 8908104

Claim:
A point-to-point radio frequency (RF), communication system comprising: one or more communication units, each coupled to a respective television camera and a respective display; and a further communication unit; wherein the one or more communication units are configured to transmit video data obtained by their respective television camera to the further communication unit at RF frequencies greater than or equal to 50 GHz and at video data rates greater than or equal to 1 gigabit/second and in the form of a QPSK, QAM, or PSK signal; and the one or more communication units are configured to receive video data for displaying on their respective coupled display, the video data having been transmitted by the further communication unit at RF frequencies greater than or equal to 50 GHz and at video data rates 250 megabits/second and in the form of a QPSK, QAM, or PSK signal; wherein each of the one or more communication units includes a single antenna for both receiving and transmitting, the antenna being coupled to an arrangement having a waveguide diplexer and an RF transceiver circuit board, the arrangement having sufficient isolation between its transmit and receive waveguides to allow transmitting and receiving at said data rates to take place point-to-point at distances greater than or equal to 1 km, and wherein each of the one or more communication units includes a transmit modem for generating the QPSK, QAM, or PSK signal, and a receive modem for processing the QPSK, QAM, or PSK signal.
