1. A system for the collection of transmission characteristics from a transmitter of a wireless communication device, the system comprising:

  • a waveguide with an interior portion sized to accept the wireless communication device at a test position therein and having physical dimensions such that the waveguide is beyond cutoff at frequencies used for communication with the wireless communication device;

    a transmitter operable at frequencies used for communication with the wireless communication device, said transmitter transmitting signals to the wireless communication device when positioned at said test position;

    a receiver operable at frequencies used for communication with the wireless communication device, said receiver receiving signals from the wireless communication device when positioned at said test position and generating receiver output signals representative of said received signals;

    an antenna coupled to said transmitter and said receiver and extending into said waveguide interior portion in proximity with said test position, said antenna coupling radio frequency signals transmitted by said transmitter to the wireless communication device when positioned at said test position and coupling radio frequency signals transmitted from the wireless communication device when positioned at said test position to said receiver; and

    a processor to control said transmitter and cause said transmitter to transmit signals to said antenna for coupling to the wireless communication device when at said test position, said processor receiving said receiver output signals representative of said received signals from the wireless communication device when at said test position.
