Patent attributes
An interference-free communication system having a central communication controller (CCC) with a wavelength-tunable light source that emits a tunable wavelength optical data signal, and controls the wavelength-tunable light source by conditioning, modulation and wavelength-tuning, the CCC includes a signal-transparent optical crossconnect and fiber optic network, a pencil-radiating antenna (PRA) that is a passive 2-dimensional diffractive module is coupled to the wavelength-tunable light source via the fiber optic network, the crossconnect routes the optical data signal to the PRA, the optical data signal is transmitted through a confined optical pencil beam, the PRA deflects the pencil beam in 2 angular dimensions as a function of a wavelength of the pencil beam, the deflected pencil beam is disposed for communication with an opto-electronic communication device, and a radio return channel that provides upstream communication from the communication device to the CCC includes a lack-of-connection communication between the communication device and the CCC.
