InstantWave High Rate 11Mbps Access Point 3Planning Your NetworkInfrastructure Network TypesAn Infrastructure network is formed by several stations and one or more AccessPoints (APs), with the stations within a set distance from the AP. Figure 1 depictsa typical Infrastructure network topology.There are three infrastructure network setups that are commonly used. It is a goodidea to understand the possible network setups and configuration requirementsbefore planning your wireless network.Type 1. The simplest wireless infrastructure network is composed of oneAccess Point (AP) and a few wireless Stations communicating viaradio waves (Figure 1). This setup enables mobile stations tocommunicate with each other. The main benefit of this type ofnetwork is to extend the range of the network. If an AP is placedbetween the stations, the radio transmission distance is effectivelydoubled since Wireless Computer-1 can talk to Wireless Computer-2through the AP. The drawback of this configuration is that theeffective bandwidth is halved since all communication is relayed bythe AP.Figure 1. Simple Wireless Infrastructure NetworkType 2. The next simplest wireless network is very similar to the Type 1network. This time the AP is connected to a wired Ethernet networkas a node. In this configuration the AP is effectively performing as abridge between the wired Ethernet and the wireless networks (Figure2).Wireless users have the same access to the network resources as theywould have if they were wired. This type of network is usually usedto extend an existing network into a difficult to wire or a roamingenvironment.WirelessComputer-2WirelessComputer-1Access Point |
