Infrastructure Network Types
An infrastructure network is formed by several stations (WWBs or WECs) and one
or more Access Points (APs), with the stations (WWB or WEC) within a set
distance from the AP. 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 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.
