Georgia Institute of Technology imagines, demos future of millimeter-wave fiber, fiber-to-wireless: The technology under development at GIT would use existing fiber-optic cables that would have their normal infrared wavelengths stepped up to millimeter-wave signals that could be received within a building and rebroadcast through 40 to 60 GHz wireless and through a simple optical filter attached to an in-wall adapter. The researchers suggest 32 separate carriers each with 2.5 Gbps data rate. They've demonstrate the capability in their labs.
