US10680343B2
An In-Building Communications system is disclosed which permits communication in tunnels, underground parking garages, tall buildings such as skyscrapers, buildings having thick walls of concrete or metal, and/or any building which has communication dead zones due to electromagnetic shielding. The invention includes a portable bi-directional amplifier (BDA) system, an outdoor antenna system attached to the building or independently mountable, an indoor antenna system attached to the building or independently mountable inside the building, and a standardized, In-Building Communications (IBC) interface box affixed preferable to the exterior of the building.
US10931026B2
A method for using a portable wireless communication device on a regional communications system in a wireless-communication dead zone or other area having a wireless-communication deficit comprising the steps of: setting up a portable donor antenna in a first location having access to an RF signal from said regional communications system; using a first coaxial cable to connect said portable donor antenna to an outdoor antenna port of a portable bi-directional amplifier kit; using a second coaxial cable to connect a portable server antenna to an indoor antenna port of said portable bi-directional amplifier kit; positioning said portable server antenna at a second location within said wireless-communication dead zone or other area having a wireless-communication deficit; activating a power switch causing said portable bi-directional amplifier kit to begin operating with power from a portable battery; receiving an RF downlink signal from said regional communications system using said portable donor antenna; conducting said RF downlink signal via said first coaxial cable to said outdoor antenna port of said portable bi-directional amplifier kit;
US11929554B2
A method for restoring radio coverage to a location when a built-in inbuilding communications system has become inoperative comprising the steps of: transporting a portable bi-directional amplifier system to a structure having an interface box; opening a door of said interface box; disconnecting a first cable from a built-in donor antenna port and a built-in bi-directional amplifier downlink port of said interface box; disconnecting a second cable from a built-in indoor antenna port and a built-in bi-directional amplifier uplink port of said interface box; connecting, using a third cable, a downlink port of said portable bi-directional amplifier system to said built-in donor antenna port of said interface box; connecting, using a fourth cable, an uplink port of said portable bi-directional amplifier system to said built-in indoor antenna port of said interface box, and powering said portable bi-directional amplifier system.
