Qualcomm is Ready to Bring You LTE Direct, Battery-Friendly Contextual Awareness

Lots of apps nowadays – from Google Now, to Foursquare, to Keep – rely on locational awareness (more commonly referred to as “geofencing”) to serve contextually sensitive information, such as the number of nearby restaurants and friends. That’s all good and fine, but those features typically rely on a combination of GPS, WiFi, and Bluetooth signals to function, which means using them requires sacrificing power.

Qualcomm thinks it may have a solution in LTE Direct. The technology, a device-to-device discovery service, piggybacks on LTE spectrum to help smartphones and tablets – thousands of devices at a range of around 500 meters, to be precise – to exchange information.  (more…)
