Wireless Internet Service Provider (WISPs)
Wireless Internet Service Provider (WISPs) are internet service providers with networks built around wireless networking. The technology used ranges from commonplace Wi-Fi mesh networking or proprietary equipment designed to operate over open 900MHz and 2.4GHz bands or licensed frequencies in the UHF or MMDS bands.
In 2005 the Federal Communications Commission released Report and Order, FCC 05-56 that revised the FCC’s rules to open the 3650 MHz band for terrestrial wireless broadband operations. On November 14, 2007 the Commission released Public Notice (DA 07-4605) in which the Wireless Telecommunications Bureau announced the start date for licensing and registration process for the 3650-3700 MHz band.
