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.
This feature can be used to create backup operation of the network in case of equipment failure. For example, you
could install two LPS-20xs, each operating on a different channel within close proximity of one another. Each
LPS-20x would communicate with a different access controller. If one of the controllers goes down, the service
sensor will detect it and shut down the radio on the affected LPS-20x. Client stations connected to this LPS-20x will
automatically be transferred to the other LPS-20x with no interruption in service. This only works if both LPS-20xs
have the same SSID or are both configured to accept any network name (default setting).
The service sensor polls the target device approximately every half second.
