For more information, see Appendix B on page 267. 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.
