Awireless LAN is normally used in a predefined environment. In such a network,
Wireless Ethernet Adapters are mounted at assigned places, each covering itsown
area in which wireless nodes can operate. These Wireless Ethernet Adapters are
connected to a wired network to communicate with each other and with servers
and clients on that network.
The 11MBPS Wireless EthernetAdapter can be connected to a 10 Mbps Ethernet
network through a RJ45 (UTP) connector.
