1. A communications apparatus configured to provide wireless network access in accordance with a communications standard that specifies a transmit OFF power threshold requirement, the apparatus comprising:

  • a hardware subsystem comprising a test signal control component, a duplexer component, and Radio Frequency processing components, the Radio Frequency processing components comprising;

    a transmitter chain portion having an output operably coupled to a transmit side port of the duplexer component; and

    a receiver chain portion having a signal sensitivity threshold associated and is operably coupled to a receive side port of the duplexer component;

    whereinthe test signal control component is arranged to cooperate with the transmitter chain to generate a test signal, a portion of the test signal being leakable by the duplexer component from the transmit side port to the receive side port thereof; and

    the test signal control component is configured to ensure that any irradiated power of the test signal complies with the transmit OFF power threshold requirement and the portion of the test signal leaked is above the signal sensitivity threshold of the receiver chain portion.
