Disconnecting clients with low RSSI

[ranz]

From what I know, the 802.11* protocols support disconnecting clients with certain parameters like RSSI and SNR.
I'm looking for an AP that supports than function. i.e when a client moves away from it it'll disconnect it once its RSSI reaches a certain low point.

Change the data rates on the low end to a higher value like 5.5 mb.

By default, the lowest data rate is 1 mb up to 54 mb. Beacons are sent at the lowest data rate and if a device can see a beacon it might try and stay connect for whatever device parameters are configured within the wireless adapter (SNR, RSSI, etc.).

If the low end rate is higher and the connected device is too far away to maintain a connection at the higher rate, it should drop the connection.

Another good reason to do this is performance. Frame retries will increase as a device is further from the AP. By default, a device will select a data rate it thinks will provide the best chance to move data based on SNR or signal strength. If excessive frame retries occurs, it will drop down to a lower data rate. Lower data rates have a higher tolerance for frame retires however, all of this hand shaking increases network overhead.
