Modeling channel availability in TV bands for devices with OSA capabilities in urban zones

Currently, the number of wireless networks has increased especially in urban zones where the concentration is enormous. This fact and the huge bandwidth consumption per device have produced spectrum scarcity in the operation bands assigned for those networks. Consequently, they have induced the search of new approaches to use the spectrum. In this context, Opportunistic Spectrum Access (OSA) has appeared as a solution for developing technologies which can sense spectrum bands to find opportunities for establishing communications (i.e. TV Bands). However, a key factor for developing devices with OSA capabilities is the measurement and modeling of the spectrum availability in the deployment zone. Therefore, in this work a study for modeling the channel availability in an urban zone for the potential use of short-range coverage devices with OSA capabilities is proposed.
