LTE, Positioning, and the Implications for GNSS Over-the-Air Testing

Evolving wireless communications technology, the incorporation of GNSS positioning into mobile devices, and increasingly crowded radio frequency spectrum are driving the creation of new specifications and standards for user equipment. Testing procedures and practices are changing in parallel with these developments and receiving additional impetus by real-world experiences such as the recent LightSquared/GPS controversy. Two engineers with extensive backgrounds in standards-setting and testing describe how these circumstances are shaping the evaluation methods for positioning capabilities in mobile devices that incorporate “fourth-generation” or 4G communications technology - including a growing reliance on over-the-air testing.
