4. Wireless Topologies
There are many wireless topologies that can be created using one or several Extension
Points. This chapter explains One-Hop, Multiple Linear, Tree and Building-to-Building
topologies. You can combine topologies to create larger, more complex networks. This
chapter also describes roaming and how it affects the number and configuration of Extension
Points.
Planning and Maintaining the Installation
For optimum performance, pre-installation planning is critical, especially if you have more
than one Extension Point.
There are two radios in the Extension Point. The Backbone (BB) radio, configured as a
Station, synchronizes with a 7510/752x/753x Access Point that is attached to the network
backbone. It can also synchronize with another Extension Point BSA radio. The Basic
Service Area (BSA) radio, configured as a Master, provides an attachment point for wireless
clients, which ultimately allows them to attach to the network backbone.
Determine Domains, Channels, Subchannels, and Master Names for each Master
on the network. Remember to include all 7510/752x/753x Access Points and
BSA radios on all Extension Points.
You can configure Backbone radios on each unit to establish a preferred Master
and fallback Masters. Map out preferred and fallback Masters for each Extension
Point.
If you plan to segment your wireless network using Domains, determine how many
Domains you need. 7510/752x/753x Access Points and Extension Points on
different Domains cannot communicate so you should plan each Domain as a
separate network.
Select Channels for each 7510/752x/753x Access Point and BSA radio of the
Extension Point in the network. Avoid using the same Channel for adjacent or
nearby cells.
