The Cisco Aironet 1520 Series mesh access points are designed to support a wide variety of applications.

The 1524SB has two 5−GHz radios are used to backhaul traffic through the mesh network, while a 2.4−GHz
radio is used for client access. As a software configuration, an 802.11a radio can also be used for client
access. With the 1524PS, a 5.8−GHz radio provides wireless backhaul, while a 2.4−GHz radio and a 4.9−GHz
radio provide access for unlicensed Wi−Fi and licensed public safety clients.

Root Access Points have wired connections, for example, Ethernet backhaul to a wired network to Wireless
LAN Controller.

Mesh Access Points have wireless connections to their Wireless LAN Controller. MAPs communicate among
themselves and back to the RAP with the use of wireless connections over the 802.11a radio backhaul. MAPs
use the Cisco Adaptive Wireless Path Protocol (AWPP) in order to determine the best path through the other
mesh access points to the controller.

This diagram shows the relationship between RAPs and MAPs in a mesh network.
