Layer 3 Network Operation; Preparing The Access Point - Cisco Aironet 1520 Series Getting Started Manual

Layer 3 Network Operation

The access points support Layer 3 network operation. Access points and controllers in Layer 3
configurations use IP addresses and UDP packets, which can be routed through large networks.
Layer 3 operation is scalable and recommended by Cisco. Figure 8 illustrates a typical Layer-3 wireless
network configuration containing access points and a controller.

Preparing the Access Point

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,
Note
consult an RF planning expert.
