Wireless: What parameters are used by a Tempest 3.0 beltpack for seamless roaming?

1) Belt-to-Base Radio Signal Strength Indication (RSSI)
2) Belt-to-Base Link Quality (LQ)
3) Base-to-Belt RSSI
4) Base-to-Belt LQ
Radio Signal Strength Indication is simply a measure of the strength of the radio signal being received. RSSI can appear to be artificially higher than it actually is in the presence of external interference because the receiver cannot tell the difference between the intended RF signal and the RF interference if they are on the same frequency. This is especially true in highly reflective environments or in the presence of significant external interference such as Wi-Fi.
Link Quality is defined as the number of successful audio packets received in one second. In any given second Tempest will attempt to send approximately 100 packets. If all of the packets arrive successfully, the LQ would be 100. If seven packets fail to arrive for one reason or another the LQ would be 93. Link Quality is updated once per second. Link Quality is roughly equivalent to the inverse of the Packet Error Rate (PER).
