to update the average received signal strength value is in the order of one second so as to account for sudden variations due to obstructions or movement. It is relatively common to miss a certain number of Beacons especially if the STA is in Power Save mode where the STA may deliberately sleep through a number of beacons. The averaging and the update time for determining the received signal strength value may need to be adjusted to account for this. TBA.1.2.1 DSC operational algorithm A sample DSC operational algorithm is shown in Figure TBA 1. In this example the following – parameter settings might be used: BeaconCountLimit: the limit of consecutive missed beacons. When exceeded the averaged signal strength of the beacon, AverageRSSI, is decremented by a value of RSSI_Decrement. An example default value is 3. UpdatePeriod: the period over which the received beacon signals are averaged. An example default value is 1 second. RSSI_Decrement: the value, in dBs, that the existing averaged beacon signal strength, Average RSSI, is decreased by if the BeaconCountLimit is reached. An example default value is 6 dB. Min_RX_Sensitivity: the minimum value for receiver sensitivity threshold, set to a value that corresponds to RX sensitivity for the STA if it was not using DSC. An example default value is -92 dBm.
