Abstract

A wireless communication network such as a 5G communication network can use MIMO technologies to enhance bandwidth between a wireless communications base station and one or more user equipment devices within a service area of the base station. RF signal repeaters can be utilized to provide one or more additional physical channels for communication between the MIMO base station and the MIMO user equipment. These RF signal repeaters can be regarded as increasing the MIMO channel diversity within the ambient environment.
