A mobile device typically connects to a WiFi network based on received signal strength indicator (RSSI). In some situations, e.g., when passing an access point at a relatively high speed, the RSSI may be high enough to connect, but only for a short period of time.
This disclosure describes techniques to select a WiFi network based on RSSI and the rate of change of RSSI (RSSI velocity). If the RSSI velocity for a WiFi network is beyond a certain threshold, the WiFi connection is determined to be temporary, and the device does not connect to the WiFi network. WiFi connections initiated with consideration for the RSSI velocity are more likely to remain connected for a usable duration of time.
