Cisco 1524SB Mesh Access Point (Part No. AIR–LAP1524SB–X–K9)
The AP1524SB is introduced in release 6.0 and can operate as a RAP or a MAP.
The AP1524SB includes three radios: one 2.4-GHz radio, and two 5.8-GHz radios.
The 2.4-GHz radio is for client access (non-public safety traffic). The two 5.8-GHz radios serves as
serial backhauls: one uplink and one downlink. The AP1524SB is suitable for linear deployments.
One of the 5.8-GHz radios can be used for universal access (client and backhaul traffic using an omni
antenna), and the other 5.8-GHz radio can be used for backhaul traffic only (directional antenna
required).
Each 5.8-GHz radio backhaul is configured with a different backhaul channel, so there is no need to use
the same shared wireless medium between the north-bound and south-bound traffic in a mesh tree-based
network.
On the RAP, the radio in slot 2 is used to extend the backhaul in the downlink direction; the radio in
slot 1 is used for client access.
On the MAP, the radio in slot 2 is used for the backhaul in the uplink direction; the radio in slot 1 is used
for the backhaul in the downlink direction as well as client access.
You only need to configure the RAP downlink (slot 2) channel. The MAPs automatically select their
channels from the channel subset. The available channels for the 5.8 GHz band are 149, 153, 157, 161,
and 165.
