Cisco Cisco Aironet 1522 Lightweight Outdoor Mesh Access Point Guía De Diseño

A public safety band (4.9 GHz) is supported on the AP1522 and AP1524PS. (See 

.)

For the AP1524PS, the 4.9-GHz radio is independent of the 5-GHz radio and is not used for the 
backhaul. On the AP1524PS, the 4.9-GHz band is enabled by default. 

In Japan, 4.9 GHz is enabled by default as 4.9 GHz is unlicensed.

For AP1522s, you can enable the 4.9 GHz public safety band on the backhaul. This can only be done 
at the global level and cannot be done on per mesh access point basis. 

For client access on the 4.9 GHz band on the AP1522, you have to enable the feature universal 
client access. 

For public safety only deployments, the AP1522 and the AP1524PS must each be connected to its 
own separate RAP-based tree. For such deployments, the 1522 must use the 4.9-GHz backhaul and 
the 1524PS must be in its own RAP tree and use the 5.8-GHz backhaul.

In some parts of the world including the U.S., you can only have public safety traffic on the 4.9-GHz 
backhaul. Check the destination countries compliance before installing.

The 4.9-GHz sub-band radio on the AP1524PS supports public safety channels within the 5-MHz 
(channels 1 to 10), 10-MHz (channels 11-19), and 20-MHz (channels 20-26) bandwidths.

The following data rates are supported within the 5 MHz bandwidth: 1.5, 2.25, 3, 4.5, 6, 9, 12, and 
13.5 Mbps. The default rate is 6 Mbps.

The following data rates are supported within the 10 MHz bandwidth: 3, 4.5, 6, 9, 12, 18, 24, and 
27 Mbps. The default rate is 12 Mbps.

Those AP1522s with serial numbers prior to FTX1150XXXX do not support 5 and 10 MHz 
channels on the 4.9-GHz radio; however, a 20-MHz channel is supported.

Those AP1522s with serial numbers after FTX1150XXXX support 5, 10, and 20 MHz channels.

When you attempt to enable the 4.9-GHz band, you get a warning that the band is a licensed band in 
most parts of the world. (See
