Local mesh
Introduction

Introduction
The local mesh feature enables you to create wireless links between one or more APs. These
links create a wireless bridge that interconnects the networks connected to the Ethernet port
on each AP. For example, AP #2 and AP #3 use the local mesh feature to create a wireless link
between the main office network and a small network in a warehouse.
Local mesh links provide an effective solution for extending network coverage in situations
where it is impractical or expensive to run cabling.
Key local mesh features include:
 Automatic link establishment: Nodes automatically establish wireless links to create a
fully-connected network. A dynamic network identifier (local mesh ID) restricts
connectivity to local mesh nodes, enabling distinct local meshes to be created with nodes
in the same physical area.
 Provides fall-back operation to recover from node failure. In a properly designed
implementation, redundant paths can be provided. If a node fails, the mesh will
automatically reconfigure itself to maintain connectivity.
 Maintains network integrity when using DFS channels. In accordance with the
802.11h standard, dynamic frequency selection (DFS) detects the presence of certain
radar devices on a channel and automatically switches the network node to another
channel if such signals are detected. 802.11h is intended to resolve interference issues
with military radar systems and medical devices.
