  Cisco Aironet 1524SB Outdoor Mesh Access Point Hardware Addendum
Warning
Do not locate the antenna near overhead power lines or other electric light or power circuits, or 
where it can come into contact with such circuits. When installing the antenna, take extreme care 
not to come into contact with such circuits, because they may cause serious injury or death. For 
proper installation and grounding of the antenna, please refer to national and local codes (for 
example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, 
Section 54). 
Statement 1052
Caution
Before connecting or disconnecting a power cord, you must remove AC power from the power cord using 
a suitable service disconnect.
Installation Guidelines
Because the access point is a radio device, it is susceptible to common causes of interference that can 
reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:
For information on planning and initially configuring your Cisco Mesh network, refer to the 
Deployment Guide: Cisco Mesh Networking Solution.
Perform a site survey before beginning the installation.
Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and 
from the access point.
The access points can be installed at any height, but best throughput is achieved when all the access 
points are mounted at approximately the same height. We recommend installing the access points 
no higher than 40 feet (12.2 meters) to allow support for wireless clients on the ground in the 
immediate vicinity of the access point; for example, directly below the access point.
Note
To calculate path loss and to determine how far apart to install access points, consult an RF planning 
expert.
Site Surveys
Every network application is a unique installation. Before installing multiple access points, you should 
perform a site survey to determine the optimum use of networking components and to maximize range, 
coverage, and network performance.
Consider the following operating and environmental conditions when performing a site survey:
Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio 
range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the 
radio data increases.
Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio 
range. As a general rule, range increases in proportion to antenna height. However, do not place the 
antenna higher than necessary, because the extra height also increases potential interference from 
other unlicensed radio systems and decreases the wireless coverage from the ground.
Physical environment—Clear or open areas provide better radio range than closed or filled areas. 
Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of 
wireless devices. Avoid locating the devices in a location where there is an obstruction between the 
sending and receiving antennas.
