Systems and methods for determining a performance metric for an antenna deployment are provided. In some embodiments, a method includes obtaining the antenna deployment including antennas and corresponding locations for the antennas, a cell assignment for the antennas such that each antenna is assigned to one cell out of one or more cells, and a resource assignment for the antennas such that each antenna is assigned to one radio resource out of one or more radio resources. Based on the antenna deployment, the cell assignment, and the resource assignment, the method determines at least one performance metric of the antenna deployment. In this way, some embodiments disclosed herein provide a lightweight & efficient method to simulate the performance of a MIMO network composed of distributed antennas. In some embodiments, the performance is realized by calculating SINR, Bitrate, and Rank for the network.
