Using only beams of light, a new networking hub is able to distribute gigabit internet to a receiver as far as 18 feet away, reports Ars Technica. Earlier this week, RiT Technologies unveiled its Beamcaster networking unit, which operates using a similar principal to fiber optics — that information can be sent using light — but instead of sending it along cabling, directs a focused laser beam through the open air to deliver the data. The primary hub must be mounted on a ceiling and have a direct line of sight with each of its eight possible receivers, which communicate using light that's invisible to humans. Once aligned, the receivers can hook directly into a computer's ethernet to provide internet, or they can connect to a router to broadcast the signal even farther.
