Planning the Network

Infrastructure Network Types

An infrastructure network is formed by several stations and one or more access
points (APs), with the stations within a set distance from the AP or APs. Figure 1
depicts a typical infrastructure network topology.
There are three infrastructure network setups that are commonly used. It is a good
idea to understand the possible network setups and configuration requirements
before planning your wireless network.
Type 1. The simplest wireless infrastructure network is composed of one
access point (AP) and a few wireless stations communicating via radio
waves (Figure 1). This setup enables mobile stations to communicate
with each other. The main benefit of this type of network is to extend
the range of the network. If an AP is placed between the stations, the
radio transmission distance is effectively doubled since wireless
computer #1 can talk to wireless computer #2 through the AP. The
drawback of this configuration is that the effective bandwidth is halved
since all communication is relayed by the AP.
