1.3.2 Wireless LAN
The wireless LAN is a common application of the transceiver. It consists
of a central control station (Access Point) and one or more associated
Remote units, as shown in
between a central WAN/LAN and remote Ethernet segments. The oper-
ation of the radio system is transparent to the computer equipment con-
nected to the transceiver.
The Access Point is positioned at a location from which it communi-
cates with all Remote units in the system. Commonly, this is a high loca-
tion on top of a building or communications tower. Messages are
exchanged at the Ethernet level. This includes all types of IP traffic.
A Remote transceiver can only communicate over-the-air to an Access
Point (AP). Peer-to-peer communications between Remotes can only
take place indirectly via the AP. In the same fashion, an AP can only
communicate over-the-air to associated Remote units. Exception: Two
APs can communicate with each other "off-the-air" through their
Ethernet connectors using a common LAN/WAN.
