New 5G video from Gleb Marchenko
From the author:
In this video, I explain 5G UE positioning (5G device localization) with possible 5G geolocation use cases. I also discuss positioning accuracy for 5G cellid, round trip time, 5G timing advance, 5G Positioning Reference Signal (5G PRS), 4G OTDOA, Angle of Arrival (5G AoA), Angle of Departure (5G AoD) methods. I explain how massive antennas array and large bandwidth can help to increase resolving of positioning signals.
You can find also example of basic questions about 5G security and privacy related to PII (Personally Identifiable Information), geo location MDT data from users. In addition, an overview of 5G Positioning Architecture with Location and Management Function (5G LMF) and Gateway Mobile Location Center (5G GMLC).
