AT&T unveils Project AirGig, Gigabit wireless delivered via power lines

AT&T announced a new project it has been experimenting with. Project AirGig is a new type of wireless infrastructure which is low-cost and is installed onto an infrastructure thats existed for decades: power lines.

AirGig essentially piggybacks onto existing power lines and is able to relay a connection using millimeter wave (mmWave) signals capable of multi-gigabit speeds to be used as public Wi-Fi access points, home broadband connections, and could be deployed for existing 4G LTE bands and future 5G technologies. AT&T says initial tests showed much promise and it plans to begin field testing in 2017.
