(Telecompaper) Facebook has unveiled two new experimental technologies it's developing as part of efforts to increase internet connectivity around the world. The Terragraph systems builds on the WiGig standard developed for wireless connections between consumer electronics, such as a computer and TV. It uses the unlicensed 60 GHz band. Using the existing components developed for WiGig offers a low-cost solution compared to traditional telecom networks to deliver high-bandwidth internet for dense. urban areas, Facebook said. The Facebook Connectivity Lab's other new project is called ARIES and focuses on efficient usage of spectrum and energy. Its proof-of-concept base station with 96 antennas can support 24 streams simultaneously over the same radio spectrum.
