Abstract: An RF characterization system includes a processor that executes program instructions to determine how a radome affects RF characteristics of an antenna by retrieving near field measurement data of the radome and antenna, receiving an electronic image representation of the radome, and obtaining near field RF properties of the radome and antenna by combining the near field measurement data and the electronic image representation.

Abstract: A protocol for initiating communications between STAR devices in a network includes communicating via a communication device having a transmit signal path and a receive signal path where the transmit signal path and receive signal path are operable to transmit and receive simultaneously at the same frequency over an interference-suppressed band. A communication sub-band and an initiation sub-band are generated within the interference-suppressed band. The initiation sub-band has a lower bandwidth than the communication sub-band. Signals may be transmitted and received signals over the initiation sub-band the communication sub-band.

Abstract: A radio frequency repeater device includes a receive antenna that receives a receive signal having a first frequency. A transmit antenna transmits a repeat signal at the first frequency, the repeat signal being an amplified version of the receive signal. A signal filter communicates with the receive antenna and transmit antenna, the signal filter being operable to amplify quadrature and non-quadrature components of an input signal associated with the repeat signal to produce a filtered repeat signal. A coupler combines the receive signal with the filtered repeat signal in such a way that the filtered repeat signal cancels interference from the transmitted repeat signal in the receive signal.

Abstract: A signal interference cancellation system includes a signal filter that receives an interference signal and is in communication with a receiver that also receives the interference signal. The signal filter includes (a) a modulation system that modulates the interference signal to generate a modulated signal, (b) a first frequency range within which the modulation system amplifies quadrature components of the modulated signal, (c) a second frequency range within which the modulation system amplifies non-quadrature components of the modulated signal, and (d) a signal adder that combines the amplified quadrature and non-quadrature components of the modulated signal from (b) and (c) to generate an interference cancellation signal. The signal filter communicates the interference cancellation signal to the receiver for cancelling the interference signal.
