Abstract
A method and apparatus for a wireless device that can adapt a rate of related wireless network unit scans for adjacent networks is disclosed. In one embodiment, the wireless device can include a wireless network unit and a co-located geo-location signal receiver, and a processor. The processor can determine the position and speed of the wireless device from data received from the geo-location signal receiver. The processor can configure the wireless network unit to adapt the rate of related wireless network scans based upon determined speed and position. In one embodiment, the wireless network unit scans can be wireless scans for other nearby networks for roaming or location based services.
Claims21
A method for reducing power consumption and enhancing user experience in a mobile wireless device, the method comprising:
- during operation of the mobile wireless device;
- receiving location signals at the mobile wireless device;
- determining a change of position of the mobile wireless device from the location signals;
- and,
- altering a period of time between network scans in accordance with the change of position of the mobile wireless device.
