Communication device and method for monitoring a wireless communication exchange

A communication device configured to operate as a wireless Sniffer device and monitor a wireless communication exchange between two wireless communication devices, the communication device comprising:

• a frequency generation and timing circuit configured to synchronize the communication device to a frequency and a timing employed between the two wireless communication devices on a main wireless communication channel;
• a receiver circuit coupled to the frequency generation and timing circuit and configured to receive the wireless communication exchanges between the two wireless communication devices on the main wireless communication channel, wherein the wireless communication exchanges comprise one of packet-based communication exchanges or tone-based communication exchanges;
• a signal processor coupled to the receiver circuit and configured to:
• process the received wireless communication exchanges;
• combine a plurality of at least one of phase measurements or magnitude measurements from the respective two wireless communication devices, following repeated operations of the monitored main wireless communication channel across a plurality of different frequencies;
• and
• determine, based on the combined plurality of at least one of phase measurements or magnitude measurements, a value of at least one of phase error or magnitude error, introduced by each of the two wireless communication devices.
