B.2 Wireless APs 26XX and 36XX
B.2.1 Wi-Fi certification
The AP26XX is Wi-Fi certified under Certification ID # WFA4279 for operation in
accordance with IEEE 802.11a/b/g. The AP26XX Wireless APs with internal and
external antennas are designed and intended to be used indoors.
The AP36XX is Wi-Fi certified under Certification ID # WFA5917 for operation in
accordance with IEEE 802.11a/b/g/n. The AP36XX Wireless APs with internal
and external antennas are designed and intended to be used indoors.
Note: Operation in the European Community and rest of the world may be
dependant on securing local licenses, certifications, and regulatory approvals.
B.2.2 AP2620 external antenna AP
Optional approved 3rd party external antennas
The AP2620 external antenna APs can also be used with optional certified
external antennas.
Antenna diversity
There are some limitations for using different antennas and Tx/Rx diversity:
• If Alternate antenna diversity is used for Tx or Rx, then the same antenna
model must be used as left and right antennas. In addition, if cables are used
to connect external antennas, the cables must be of the same length and
similar attenuation. If these rules are not respected, antenna diversity will not
function properly and there will be degradation in the link budget in both
directions.
• You can choose to install only one antenna provided that both Tx and Rx
diversity are configured to use that antenna and only that antenna. You can
choose to install one antenna for 11b/g band and one antenna for 11a band,
provided that the antenna diversity is configured appropriately on both radios.
Sensor support
Changing the antenna on sensors is not supported (at this stage) for the following
reasons:
• The sensor factors the antenna gain and pattern in its calculations and
therefore it needs to know the antenna type and gain.
