SERVICE SENSOR
The service sensor enables the LPS-20x to determine if access to the network or a particular server is available. If
not, the LPS-20x automatically shuts off its radio transmitter taking down the wireless cell. The service sensor polls
the target device approximately every half second. For more details, refer to Service Sensor on page 94.
ROAMING
Client computers are able to move between wireless cells (called roaming) without losing contact with the network
(Figure 11). This is possible because the wireless network adapters in the client computers automatically switch to
the best available device. Authentication and billing (if used) are maintained. Figure 11 shows roaming across
several LPS-20xs.

MAC-LEVEL FILTERING
When enabled, this option enables you to control access to the wireless network based on the MAC address of
client stations. You can either block access or allow access depending on your requirements.
LOCATION-AWARE AUTHENTICATION
This feature enables you to control logins to the public access network based on the wireless access point a
customer is connected to. This feature works when you use the LPS-20x in conjunction with an LPS-21x or a
Colubris access controller (e.g., CN3000) that also supports the Location-Aware Authentication. If you enable this
option, when a customer attempts to login to the public access network, the access controller sets the Called-
Station-ID in the RADIUS access request to the MAC address of the wireless port the customer is associated with.
Server-side code can be written to manage access based on this information.
