Evaluating channel capacity oportunities for potential use by short range devices based on OSA

Abstract:

Dense urban zones with high concentration of Wireless networks can degenerate in problems such as spectrum scarcity for devices in licensed bands, or high interference levels for devices in unlicensed bands, thus producing QoS problem. A possible solution to deal with this issue is the use of wireless devices to access opportunistically a licensed band. For this reason, this paper evaluates a channel's probabilistic model in urban zones to allow unlicensed band devices to access the licensed bands (e.g. TV Band) in an opportunistic way. As result of this study, the channel capacity of the band is compared with different technologies.
