The document discusses TV white spaces, which are unused portions of spectrum between 54 MHz and 698 MHz that have been made available by the FCC for unlicensed use. Large amounts of white space spectrum are available, especially in rural areas, providing opportunities for wireless internet service providers, private networks, and state/local governments. Key points covered include characteristics of fixed and portable white space devices, coverage improvements over WiFi, and the IEEE 802.22 standard being developed for wireless regional area networks using white spaces.
