Page 15: Planning The Network
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. -
Page 16: Figure 2. Single Ap Network
Type 2. The next simplest wireless network is very similar to the Type 1 network. This time the AP is connected to a wired Ethernet network as a node. In this configuration the AP operates as a bridge between the wired Ethernet network and the wireless networks (Figure 2). -
