SECTION 2 " Features and Functional Overview

Access Point Bridging Layer

The 6710 Access Point functions as a bridge with up to four ports:

"An Ethernet port.

"One or two radio ports.

"An Open Wireless LAN/Internet Protocol (OWL/IP) port.

The access point is a translating bridge because it forwards frames between Ethernet and wireless media that have unique physical and MAC protocol implementations. The access point implements the basic learning and forwarding functions of a simple wired LAN bridge. It also includes additional functionality to address unique problems in wireless LANs.

Significant functions supported at the bridging layer include network organization, support for roaming and power-managed stations, and programmable flooding levels.

Network Organization

Open wireless LAN networks may be complex, supporting:

"Small or large numbers of access points on a single wired LAN backbone.

"Stations that roam between coverage areas and employ power management to improve battery life.

More complex topologies include the following:

"Range extension through wireless access points, which are not connected to the wired LAN backbone.

"Secondary LANs (connection of wired LAN segments by wireless links).

"Mixed radio frequency (RF) media.

"Operation over multiple IP subnets.

"Multiple, independent wireless LANs on one wired LAN backbone.
