Cisco Cisco Aironet 1522 Lightweight Outdoor Mesh Access Point 설치 가이드

The access point is a radio device which 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 Cisco 
Mesh Networking Solution Deployment Guide or the Cisco Aironet 1500 Series Wireless Mesh 
AP Design Guide. These documents are available on cisco.com.

Do not install the access point in an area where structures, trees, or hills obstruct radio signals to 
and from the access point.

You can install the access point at any height, but best throughput is achieved when the access 
points are mounted at the same height.

To perform path loss calculation and to determine how far apart to install access points, 
consult an RF planning expert.

Cisco recommends that you perform a site survey before installing the equipment. A site survey reveals 
problems that can be resolved before the network is operational. Because 802.11a is unlicensed, there 
may be sources of interference from other 802.11a wireless devices (especially in multi-tenant 
buildings) that could degrade your 802.11 signals. A site survey can determine if such interference 
exists. 

A proper site survey involves temporarily setting up mesh links and taking measurements to determine 
whether your antenna calculations are accurate. Determine the correct locations and antenna types 
before you drill holes and route cables and mounting equipment.
