Manhattan is being blanketed in overlapping hotzones by Telkonet, a Maryland-based ISP, in conjunction with Microwave Satellite Technologies (MST) and its NuVisions trademark. Together they provide Wi-Fi along with voice, video and data services by connecting Gigabit Ethernet to building powerlines then adding high-power access points. By servicing off private property, Telkonet doesn’t require access to city-owned property like light poles. The company offered an option to the city of New York to create a similar network, but was turned down.
