1. A method of scanning for access points (APs), the method comprising:
- measuring a variable related to range and movement of a mobile device, the mobile device executing code to perform the measuring;
analyzing whether the variable is significant enough to trigger a first scan request, the mobile device executing code to perform the analyzing;
scanning for APs in response to the first scan request, the mobile device executing code to perform the scanning.

Abstract
A method of scanning for APs includes measuring a variable related to movement of a mobile device, the mobile device executing code to perform the measuring. The method further includes analyzing whether the variable is significant enough to trigger a first scan request, the mobile device executing code to perform the analyzing. The method further includes scanning for APs in response to the first scan request, the mobile device executing code to perform the scanning.

9. A system for scanning for APs, the system comprising:
-
a computing system including a plurality of modules, including; a RSSI measurement module configured to calculate calculated received signal strength indications (RSSI) based on the signal strength of received frames for each of a plurality of APs; an analysis module including a RSSI threshold comparator, the RSSI threshold comparator configured to receive the calculated RSSI and compare the calculated RSSI and compare the calculated RSSI to a first threshold and when the calculated RSSI has crossed the first threshold create a first scan request; a scan scheduler module configured to receive the first scan request and generate a first scan indication; a scan executor module configured to perform a first scan of APs responsive to a first scan indication from the scan scheduler based on the first scan request. - View Dependent Claims (10, 11, 12, 13, 14, 15)
