Abstract
Various embodiments for providing enhanced power savings in mobile computing devices are described. In one or more embodiments, a mobile computing device may include a motion sensor to detect when the device is in motion. The mobile computing device may include a radio processor that may select from among several signal search procedures based on whether the device is in motion, and whether a signal is detectable and adequate. Other embodiments are described and claimed.
Claims13
A method operating on a wireless computing device, the method comprising:
- detecting whether the device is in motion;
- detecting whether a wireless signal has adequate strength at the system;
- and
- when the device is not in motion,
- executing a first signal search procedure comprising maintaining a connection to a current signal source and not searching for a stronger wireless signal from among neighboring signal sources when the wireless signal is adequate and searching for a stronger wireless signal from among neighboring signal sources at an increased search interval when the wireless signal is not adequate while avoiding searching the current signal source;
- and
- when the device is in motion,
- executing a second signal search procedure comprising maintaining a connection to a current signal source and searching for a stronger wireless signal from among neighboring signal sources when the wireless signal is adequate and searching for a stronger wireless signal from among neighboring signal sources at a search interval when the wireless signal is not adequate.

A non-transitory machine-readable storage medium comprising instructions that when executed enable a mobile computing system to:
- detect whether the system is in motion;
- detect whether a wireless signal has adequate strength;
- and
- when the system is not in motion,
- execute a first signal search procedure comprising maintaining a connection to a current signal source and not searching for a stronger wireless signal from among neighboring signal sources when the wireless signal is adequate and searching for a stronger wireless signal from among neighboring signal sources at an increased search interval when the wireless signal is not adequate while avoiding searching the current signal source;
- and
- when the system is in motion,
- execute a second signal search procedure comprising maintaining a connection to a current signal source and searching for a stronger wireless signal from among neighboring signal sources when the wireless signal is adequate and searching for a stronger wireless signal from among neighboring signal sources at a search interval when the wireless signal is not adequate.
5 more elements
An apparatus comprising:
- a motion sensor to detect when the apparatus is in motion;
- and
- a radio processor coupled with the motion sensor, the radio processor to detect whether a wireless signal has adequate strength at the apparatus;
- and
- when the apparatus is not in motion, the radio processor further to execute a first signal search procedure comprising maintaining a connection to a current signal source and not searching for a stronger wireless signal from among neighboring signal sources when the wireless signal is adequate and searching for a stronger wireless signal from among neighboring signal sources at an increased search interval when the wireless signal is not adequate while avoiding searching the current signal source;
- and
- when the apparatus is in motion, the radio processor further to execute a second signal search procedure comprising maintaining a connection to a current signal source and searching for a stronger wireless signal from among neighboring signal sources when the wireless signal is adequate and searching for a stronger wireless signal from among neighboring signal sources at a search interval when the wireless signal is not adequate.
