Wireless Broadband can be defined as a new technology that provides high-speed wireless internet and data network access over a wide area. According to 802.16-2004 standard, broadband means having instantaneous bandwidth greater than 1 MHz and data rates greater than 1.5 Mbit/s. It means that their features speed is equivalent to wired broadband access, for example Digital Subscriber Line (DSL) and cable modem.

Most broadband wireless access is estimated to have a range of 50 km (approximately 30 miles) from its tower. A wireless broadband connection can be either licensed or unlicensed. Most Wireless Internet Service Providers (WISPs) use unlicensed band which is publicly shared because licensing is usually expensive. These bands are reserved for large companies that want to guarantee private access to spectrum for use in point to point communication.
