Spectrum Broker by Geo-Location Database
Geo-location database driven white space network is a very promising approach for improving secondary spectrum utilization. In this paper, the authors consider the business modeling for geo-location database driven white space network. In their proposed model, the database acts as a spectrum broker buying (reserving) bandwidth from spectrum licensees in advance, and then resells the reserved bandwidth to unlicensed White Space Devices (WSDs) in real-time. They study the optimal bandwidth reservation for the database with WSDs' demand uncertainty under both information symmetry and asymmetry. Under information symmetry, the database and the WSD experience the same degree of uncertainty about the market demand.
