title: Simulation of Beamforming using FD-MIMO for LTE-Advanced Pro in an Urban Small Cell | Remcom
description: This presentation demonstrates a new predictive tool for simulating Full Dimension Multiple Input, Multiple Output (FD-MIMO) in urban environments.  We evaluate a hypothetical small cell base station employing FD-MIMO for cases using different numbers of transmit antennas, then analyze predicted multipath in the environment and compare performance of beamforming techniques for each of the simulated cases.

Full Dimension Multiple Input, Multiple Output (FD-MIMO) is a promising new technology in LTE-Advanced Pro.  With 3GPP expanding the potential transmit antennas for LTE-A Pro eventually to as many as 64, detailed modeling of the channel characteristics is becoming increasingly complex.  [Remcom’s Wireless InSite® MIMO](https://www.remcom.com/5g-mimo) can be used to predict performance for FD-MIMO systems in urban environments.

This presentation demonstrates an innovative new simulation capability that uses three-dimensional ray-tracing to fully characterize channels, with significant optimizations to limit the additional computation required to predict the channel matrices for base stations using FD-MIMO.  We use results from simulations to evaluate a hypothetical small cell base station employing FD-MIMO for cases using different numbers of transmit antennas.  We then analyze predicted multipath in the environment and compare performance of beamforming techniques for each of the simulated cases.
