Terabeam Corporation, a developer of wireless broadband telecommunication systems, has been awarded its tenth patent by the United States Patent and Trademark Office related to its free space optics (FSO) and millimeter wave (MMW) transmission systems.
The patent, numbered 6,483,621, covers a method for preventing interference and increasing the performance of Terabeam’s pointing and tracking technology that was developed to automatically align the system’s invisible, eye-safe laser beams. This is a key patent for Terabeam and noteworthy for any FSO system operating at 1550 nanometers and utilizing this wavelength’s high power and high data rate capacities. Free space optics systems that use this wavelength require new tracking technologies compared to those used historically in near-infrared FSO systems.
