Physical Installation:

  1. Set the APs as far apart as possible with no line-of-sight to prevent
    wireless interference. 
  2. On each floor set them in a zigzag pattern preferably with walls in
    between. 
  3. Do not install them along the hallway. Install them inside the rooms.
  4. Set the APs in a staggered pattern from floor-to-floor. APs should not
    be mounted on top of each other.

Recommended Settings:

  1. Plan the channel assignment for each AP on each band. 
  2. Each AP should be on alternating non-overlapping channels to avoid
    co-channel interference. 
  3. Consider not only the APs on the same floor but also APs above and below
    when planning the channel assignment.

2.4GHz Wireless:

  • A. Set the Channel HT mode to 20MHz only and disable Auto-channel. 
  • B. Alternate the (3) non-overlapping channels, namely, channels 1, 6,
    and 11. Please account for the APs above and below as well.
  • C. WPA2-PSK(AES only) is the recommended wireless security setting.
  • D. To avoid wireless interference, try to reduce the cell size by
    decreasing the transmit power to 14dBm. Increase by 3dBm if necessary.
    There should only be a slight overlap from AP to AP if at all.

5Ghz Wireless:

  • A. Set the Channel HT mode to 40MHz only and disable Auto-channel.
  • B. Alternate channels from UNI-I, UNI-II and UNI-III. Account for the
    APs above and below as well.
  • C. WPA2-PSK (AES only) is the recommended wireless security setting.
  • D. To avoid wireless interference, try to reduce the cell size by
    decreasing the transmit power to 17dBm. Increase by 3dBm if necessary.
    There should only be a slight overlap from AP to AP, if at all.

Note: 2.4GH wireless signals have longer range and better wall penetration
compared to the 5GHz band on the same transmit power hence the difference
in their transmit power settings.
