INTRODUCTION TO THE WIRELESS ACCESS POINT
The LPS-20x wireless Access Point (AP) series are remote units that are designed to work in conjunction with
Remote Authenication Dial-In User Service (RADIUS) Servers, access controllers or similar products (Figure 10).
The role of the LPS-20x is to extend the wireless network and provide intelligent data forwarding to maintain the
security of the network.
The LPS-20xs are interconnected using a backbone LAN or are daisy-chained together. This makes it easy to add
more wireless coverage to service additional floor space or an increasing number of users.
Figure 10. LPS-20x
The LPS-20x provides wireless network coverage in a radius of up to 100 meters (300 feet). It uses radio waves in
the 2.4 Ghz band to communicate with client stations. To maintain the security of individual client stations on the
wireless network, the LPS-20x does not forward data between wireless client stations by default.
INTELLIGENT BRIDGE
Unlike a traditional bridge which automatically forwards all traffic between ports, the LPS-20x can apply security
filters to maintain the security of the network. When enabled, these filters essentially block all traffic that is not
addressed to or received from the access controller.
