Implementations relate to utilizing cellular signals to determine device location. In some implementations, a method includes obtaining location fingerprints, each fingerprint associated with a respective geographic location and being based on cellular signal characteristics at that location including multiple channel impulse responses (CIRs) for each location fingerprint for signals received from a plurality of cellular nodes. A fingerprint map is formed that references the location fingerprints. A request may be received for a particular geographic location of a particular user device, and a particular location fingerprint is obtained for the particular device that indicates cellular signal characteristics at the particular location, including CIRs for signals received from multiple cellular nodes. The particular fingerprint is compared to location fingerprints in the fingerprint map, a matching location fingerprint in the fingerprint map is selected, and an associated geographic location is output as the particular location of the particular device.

An edge device includes an antenna array and control circuitry. The control circuitry senses a surrounding area of the edge device by use of a first portion of the antenna array to track a user equipment (UE) in motion in a first communication range. The first communication range is greater than a second communication range of the edge device. The control circuitry performs preprocessing for beamforming of a radiation pattern based on the tracking. The preprocessing is performed before the UE enters the second communication range. The control circuitry executes the beamforming to direct a beam of RF signal to the UE in motion by use of one or more second portions of the antenna array. The beam of RF signal is directed in the radiation pattern as the UE enters the second communication range, and the beam of RF signal has a signal strength greater than a threshold.
