Chapter 1 Overview

Point-to-Multipoint Bridging

The access points can be used as a RAP to connect multiple remote MAPs with their associated wired
networks (see
Ethernet bridging, you must enable bridging on the controller for each access point.
Wireless client access can be provided over the bridging link; however, if bridging between tall
buildings, the 2.4-GHz wireless coverage area might be limited and possibly not suitable for direct
wireless client access.

Mesh Network
The access points are typically deployed in a mesh network configuration. In a typical mesh deployment,
one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs
without wired network connections use the backhaul feature to optimally link to a RAP that is connected
to the wired network. In the mesh network, the links between the access points are referred to as the
backhaul links.
Intelligent wireless routing is provided by the patented Adaptive Wireless Path Protocol (AWPP). This
enables each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with
the wired network connection by calculating the cost of each path in terms of signal strength and the
number of hops required to get to a controller.
