Location and positioning technologies are some of the most interesting areas of advancement in 5G. New use cases, from autonomous vehicles to real-time remote control, are driving the need for significant improvements in the accuracy, speed and availability of positioning information. 5G is stepping up to the plate with enhancements to current 4G positioning techniques such as A-GNSS and OTDOA, as well as completely new techniques (such as using beamforming information to determine vertical position).

This white paper contains a brief overview of existing cellular location techniques, discusses the new positioning methods becoming available with 5G, and how existing 4G LTE location techniques are being enhanced to serve the 5G environment. It also cove
