A cellular network system and method provided herein are directed to generating an area topographic map of a surrounding area of the cellular network system. The cellular network system comprises a transmitter, a receiver, memory, and one or more processors (processors) communicatively coupled to the transmitter, the receiver, and the memory. The memory stores computer-executable instructions that, when executed by the processors, perform certain operations. The transmitter transmits in a target direction a first signal, which is a communication signal intended for a user equipment (UE) and the receiver receives a second signal. The processors determine whether the second signal is a reflected signal associated with the first signal, determine topographic data associated with the surrounding area of the cellular network system in the target direction based at least in part on the second signal, and generate the area topographic map of the surrounding area based on the topographic data.
