Development and Implentation of a TV White Space Geolocation Database for IEEE 802.11af System Using the ITU-R P.1411 Recommendation

As the world continues to push boundaries, so as the capabilities of technology. Through wireless innovations and infrastructures, people have never been as connected as before. This study rides on with these innovations specifically in the frontier of TV White Space through developing and implementing a Geolocation Database on the basis of the ITUR P.1411 recommended propagation models. Propagation models are the core of a Geolocation Database and ITU-R P.1411 was used to suit short-range outdoor communications in the 300MHz to 100GHz frequency range such as the IEEE 802.11af standard. The keep-out distance calculated from the ITU-R P.1411 recommendation along with the licensed TV channel’s service contour was used to estimate the TVWS in the province of Cebu, Philippines. The developed Geolocation Database was able to estimate about 30 MHz of available licensed TV channels mostly located in the northern and southern ends of the Cebu province. It was also successfully implemented with the IEEE 802.11af system.
