Abstract

An active antenna may be installed within a ceiling assembly of a building to improve the range of a wireless and/or cellular network. Further, a ground plane may be installed throughout the ceiling to reduce the occurrence of multipath interference of radio frequency (RF) signals. In addition, one or more active and/or passive antennas may also be installed in the ceiling to further extend the range of the wireless and/or cellular network within the building. Each of the antennas may be designed to facilitate (RF) signal gain for a collection or range of frequencies. In some instances, the installation of active and/or passive antennas may increase the range of a communications network, while the installation of a ground plane throughout the ceiling may reduce the occurrence on multipath interference resulting in improved wireless and/or cellular network performance including increased bandwidth and range.
