A system that will improve wireless coverage
inside buildings is to be launched by a Cambridge UK firm ZinWave. Utilising fibre-optic cables that are already installed, ZinWave will deliver base stations that can send wireless signals over installed multi-mode fibre, providing blanket coverage inside buildings for GSM, 3G, Wi-Fi and much more.
Distributed antenna systems (DAS) improve the coverage of radio within buildings by centralising the base stations in wiring closets, and distributing the antennas throughout the building. Most systems use a fibre-coax network, which has to be purpose-built, but Zinwave claims its proprietary technology lets it use installed multimode fibres, instead of having to pull new ones through the building.
