Rate Adaptation
Rate Adaptation Mode - Choose PER (default) or EVM. The PER mode adjusts modulation based on the Tx Packet
●
Error Rate calculated on the local radio. The EVM mode adjusts modulation based on the Error Vector Magnitude
reported by the remote radio.
PHY Rate - Choose Conservative (default) or Aggressive. The Conservative mode results in the lowest PER, but
●
can also prevent higher modulation. The Aggressive mode optimizes modulation, but can also result in higher
PER.
The table below describes the PER limit above which Rate Adaptation will reduce modulation to maintain a stable
link.
