What is the new 802.22 Wi-Fi standard for Wireless Regional Area Networks in TV Whitespaces?
The new IEEE 802.22 standard has been published and will finally allow manufacturers to start producing standardized devices that will use the white space vacated by analog TVs over two years ago. The standards will provide networking in areas over a 62 mile radius at speeds of up to 22Mbps.
The frequencies now available, from 54MHz to 698MHz, can maintain signal over vast distances, so a single device may provide an incredibly large coverage area of up to 12,000 square miles. According to the new IEEE standard, 802.22-capable equipment will broadcast WRANs (wireless regional area networks) that can deliver signal to this vast coverage area.
