2 Introduction to the Access Point
The Cisco Aironet 1552S Outdoor Mesh Access Point (hereafter called the access point or AP) is a
ruggedized outdoor access designed for service in mesh networks in hazardous locations. It contains
an ISA100.11a sensor backbone router to communicate with wireless sensors, and the access point
radios provide backhaul service to carry sensor data to your network. The 1552S access point
leverages 802.11n and 802.15.4 technology with integrated radio and internal/external antennas.
The 1552S outdoor platform consists of Multiple Input Multiple Output (MIMO) WLAN radios and
with integrated spectrum intelligence (CleanAir). CleanAir provides full 11n data rates while
detecting, locating, classifying and mitigating radio frequency (RF) interference to provide the best
client experience possible. CleanAir technology on the outdoor 11n platform mitigates WiFi and
non-WiFi interference on 2.4 GHz radios.
The 1552S access point offers multi-band 2.4-GHz and 5-GHz configurations with an option to
configure access and backhaul radios. The radios are called 2.4-GHz MIMO radios and 5-GHz MIMO
radios. The 2.4-GHz radios are used primarily for local access and the 5-GHz radios for both local
access and wireless backhaul in the mesh mode.
The 1552S access point supports the modularity of the 1520 series and allows flexibility in radio
configuration. In addition to full interoperability with 802.11n clients, the 1552S access point
interoperates with legacy clients and offers enhanced backhaul performance.
The access point is a standalone unit that can be wall or tower mounted. The access point can also
operate as a relay node for other access points not directly connected to a wired network. Intelligent
wireless routing is provided by the Adaptive Wireless Path Protocol (AWPP). This enables each access
point to identify its neighbors and intelligently choose the optimal path to the wired network by
calculating the cost of each path in terms of signal strength and the number of hops required to get to
a controller.
The access point is configured, monitored, and operated through a Cisco wireless LAN controller
(WLC), referred to as a controller in this document. The WLC is described in the appropriate Cisco
Wireless LAN Controller Configuration Guide. The Cisco Mesh Networking Solution Deployment
Guide describes how to plan and initially configure the Cisco mesh network, which supports wireless
point-to-multipoint mesh deployments. The controllers use a browser-based management system, a
