Hardware Features
Point-to-Multipoint Mesh Network
The access point is 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 . Depending on the version of software being used, these links can utilize either 2.4 GHz
or 5 GHz as of (8.2.100 and above).
Intelligent wireless routing is provided by the 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 with signal strength given priority since signal strength determines
the data rate available for backhaul.
Figure 1-16 illustrates a typical mesh configuration using MAPs and RAPs.

The Cisco 1552SA/1552SD is a universal and multifunctional outdoor wireless mesh network that
supports not only Wi-Fi devices and applications, but also supports wireless field I/Os and actuators on
both ISA100 Wireless and WirelessHART protocols.
Along with robust and reliable Cisco Outdoor Wi-Fi wireless mesh, it also creates parallel Industrial
Wireless Automation Network to support field sensors and actuators running on either or both of the two
protocols. The Multiprotocol Radio module manages and aggregates Industrial Wireless Data and passes
it over to the Cisco Wireless Mesh backbone
