1. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
determining estimated positions of respective points corresponding to respective reflecting elements of an intelligent reflective surface, comprising:
transmitting respective first, second, and third calibration signal data from a transmission point to respective first, second, and third reflecting elements located at respective first, second, and third points;
receiving, in response to the transmitting of the respective first, second, and third calibration signal data, respective first, second, and third reflected signal data at a receiver proximate to the transmission point;
estimating respective first, second, and third positions of the respective points based on respective first, second, and third difference data between the respective first, second, and third transmitted calibration signal data and the respective first, second, and third reflected signal data;
determining a plane angle of the intelligent reflective surface based on the respective first, second, and third positions; and
determining respective positions of respective other points corresponding to respective other reflecting elements based on the plane angle and fixed distance values between the respective points corresponding to the respective reflecting elements.
