Location :: Augmented Positioning

The whole point of mobile apps is the ability to use them anywhere. That is especially important for the growing number of apps we use to find our way, search for people and things, and discover local services. However, location-based apps are often challenged in environments where GNSS signals are unavailable, or where continuous tracking consumes too much power for mobile devices.

The IZat™ platform leverages Qualcomm’s strengths in cellular, Wi-Fi and sensor technologies to address these requirements and provide a superior experience for consumers. Qualcomm® IZat location engines support the most advanced positioning techniques to raise the bar on location performance with virtually no impact on mobile battery life or design cost.

Near Zero-Power Location Awareness

Qualcomm’s integrated location solutions provide always-on location awareness without consuming additional power. IZat location engines and assistance servers support standard AFLT, OTDOA, and enhanced Cell ID techniques over existing signals. In addition to providing continuous location awareness, these techniques accelerate GNSS acquisition and provide a reliable fallback when satellite signals are unavailable.

WLAN Positioning

The proliferation of Wi-Fi networks has established a robust system of base stations and access points around the world. Mobile devices can use power measurements to help determine their exact location in relation to nearby networks. The Qualcomm IZat platform supports WLAN positioning with cloud-based servers and a global database of WLAN access point locations.

Sensor Assistance

Virtually all mobile devices now use sensors that detect movement, orientation, speed and altitude. Qualcomm IZat location engines process measurement from these inertial sensors – including accelerometers, gyroscopes, compasses and altimeters– to provide greater accuracy and orientation. Sensor assistance can also bridge the gap in areas where satellite signals are not accessible, to significantly improve tracking capabilities for automotive and pedestrian navigation.
