Antennas For Outdoor Deployments - Cisco Aironet 1850 Series Deployment Manual

Antennas for Outdoor Deployments

The AP 1850 is designed for indoor deployments. However, using a NEMA enclosure or mounting the antenna outdoors may be
acceptable (depending upon your location as some countries do not permit this).
In the U.S., installers who need to deploy APs outdoors are recommended to use the "P" series products such as the Cisco Aironet
AP 3600P and AP 3700P. For more information, See the
All Cisco antenna connectors are labeled as "A," "B," "C," and so on. "A" has a higher priority than "B" or "C/D". So, if the AP supports,
for example 3 or 4 antennas and you only have 2 antennas, you can use them on ports "A" and "B" for a short period until you install
the additional antennas provided you turn off the unused antenna ports on the controller or AP software.
While it is not recommended to use less antennas, the product (in a pinch) supports 802.11a/b/g clients or single spatial stream .11n
clients using only one or two antennas. However, there is a significant performance hit and you will also lose ClientLink functionality.
If you do this, you will also have to configure the AP in the software to not use the other antenna. Failure to do so could result in
performance issues.
The following Dual Radiating Element (Dual-Band) antennas are approved for use with the AP 1850e series access point:
• AIR-ANT2524DB-R= Dipole Black 2dBi @ 2.4 GHz – 4dBi @ 5 GHz
• AIR-ANT2524DG-R= Dipole Gray 2dBi @ 2.4 GHz – 4dBi @ 5 GHz
• AIR-ANT2524DW-R= Dipole White 2dBi @ 2.4 GHz – 4dBi @ 5 GHz
• AIR-ANT2535SDW-R= Short Dipole 3dBi @ 2.4 GHz – 5dBi @ 5 GHz
• AIR-ANT2524V4C-R= MIMO Omni Ceiling 2dBi @ 2.4 GHz – 4dBi @ 5 GHz
• AIR-ANT2566P4W-R= MIMO Patch 6dBi in both bands
• AIR-ANT2544V4M-R= MIMO Wall Mount Omni 4dBi in both bands
