How Wireless Voice Link Works
The WVL is a radio pair that operates in the 2.4 GHz unlicensed radio band. The handset
communicates wirelessly with the base station located inside the simulator. The base station
converts the digitized microphone stream from the handset and outputs it via the base station to the
headphone and line out jacks. The output projects through the head speakers inside the simulator.
To accommodate multiple WVL pairs in close proximity, each WVL is assigned two RF channels on
which to operate. The RF channels divide up the 2.400 – 2.4835 GHz spectrum in 80 single
frequencies to prevent the WVLs from interfering with each other.
Due to the nature of the unlicensed 2.4 GHz band, there may be other devices such as Wi-Fi,
microwave ovens or Bluetooth® radios operating in the 2.4 GHz band as well. Therefore, two
channels are used to transmit the audio stream redundantly to avoid interference. In case there is an
interference in one channel, the other can be used to extract the audio stream.
To operate correctly, both the handset and base station should be set to the same frequency using
the DIP switches located in the devices. If the interference is too high, the WVL firmware has the
ability to change channels automatically to avoid interruption. This process occurs simultaneously in
both the handset and the base station without the need for user intervention. The units revert back
to the original frequency set on the DIP switches when both devices are restarted using the power
switch.
