This document discusses a compact Flexi Multiradio 3-sector solution that provides leading RF performance with new technology. It allows for easier installation with one optical and DC cable, no long antenna feeders, lowest total weight and power consumption for 3-sector sites. The standard Flexi RF Module can be installed close to the antenna for maximal performance with no feeder losses. It also describes how a second 3-sector RF Module can be added for MIMO evolution, providing up to 1+1+1 at 360/480W with 2TX MIMO and optional 4-way UL diversity.
