Microsoft Keynote: A Fresh Look at Mobile Location Sensing

Location-based services have become ubiquitous thank to the sensors like GPS and WiFi in our smart phones and other mobile devices. However, continuous location sensing such as logging, tracking, and geo-fencing, consume too much energy and shorten device battery life. In this talk, we take a fresh look at location sensing, in both outdoor and indoor settings. For outdoor location, we dive into the principles of GPS receivers and show that by offloading GPS processing to the cloud, we can reduce the device side energy consumption by three orders of magnitude. For indoor location, we discover that commercial FM signals are good sources of location signatures that work better than WiFi signatures by themself, and works even better if combined with WiFi signatures. These low energy approaches enable always-there location services without users paying battery life penalty.  <http://cts.vresp.com/c/?YourCompanyName/a17c4f05e8/a2a4e77231/6d13f0b944> Read more >>


Microsoft CLEO TechShow:
Energy Efficient GPS Sensing with Cloud Offloading 


Location is a fundamental service for mobile computing. Typical GPS receivers, although widely available, consume too much energy to be useful for many applications. Observing that in many sensing scenarios, the location information can be post-processed when the data is uploaded to a server, Microsoft CLEO team designs a Cloud-Offloaded GPS (CO-GPS) solution that allows a sensing device to aggressively duty-cycle its GPS receiver and log just enough raw GPS signal for postprocessing. Leveraging publicly available information such as GNSS satellite ephemeris and an Earth elevation database, a cloud service can derive good quality GPS locations from a few milliseconds of raw data. Compared to more than 30 seconds of heavy signal processing on standalone GPS receivers, three orders of magnitude lower energy consumption per location tagging can be achieved using this design.  <http://cts.vresp.com/c/?YourCompanyName/a17c4f05e8/a2a4e77231/b150032d36> Read more >>
