Some other service related data may influence this algorithm processing. As an example, voice deployments for which Cisco recommend as a general guideline these set of configurations :

  • Minimum signal power -67dbm,
  • SNR, at least 25db,
  • A minimum rate of 11Mbps,
  • A minimum of two neighboring access points at at least -75dbm transmit power level,
  • A minimum of 4 overlapping channels at a minimum of -80dbm transmit power level,
  • A 300 ms maximum of RTT,
  • A maximum of 2% packet loss.
