The first worldwide application of Cognitive Radio (CR) networks in unlicensed television broadcast bands is IEEE 802.22 Wireless Regional Area Network (WRAN). This paper introduces the implementation of IEEE 802.22 Wireless Regional Area Network (WRAN) for broadband Internet access in sub-urban areas. The authors have investigated how CR through dynamic spectrum access facilitates the efficient use of underutilized spectrum (white spaces). To do this, they have analyzed a coverage planning for WRAN and compared it with a traditional wireless communication standard, IEEE standard 802.16e.
