Client Power, Best Practices, Channel Topology & Range

[notes]
Client power should be adjusted to match the AP power settings.
Maintaining a higher setting on the client does not result in higher performance and it can cause interference in nearby cells.

Antennas give the WLAN three fundamental properties:
     gain
     direction
     polarization

Best Practices:
  Number of users per AP 15-25 (data only)
                                                7-8 (voice)
           limit data rates

Changes to the channel topology causes clients to reassociate, and calls to drop.  Change sin AP power do not impact client connectivity.

Range is generally affected by a factor of a 30% increase (approximately) for every halving of a data rate.
