Besides being the first to map some of the most recognized buildings in the world, Nokia also offers the world’s broadest coverage of indoor spaces with currently more than 9,000 venues consisting of 50,000 unique buildings mapped in 69 countries. They are also supplying this indoor map data to partners such as Microsoft. Now, Nokia has teamed up with Qualcomm’s IZat platform for improving the accuracy of indoor mapping and increasing the coverage as well. Qualcomm’s IZat platform uses the following technologies that enables more robust positioning inside building where traditional satellite signals are unavailable.
Here are the ways by which Qualcomm’s IZat provides augmented positioning.
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.
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.
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.
As a result, Nokia is trying to provide a great indoor navigation system around the world as they now offer for outdoor navigation.
