7.9.1 Wireless Network Overview
Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can connect with
numerous wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and wireless clients,
extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or more wireless
clients. The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless clients connect to
one another in order to exchange information.
