Abstract :
This paper presents a characterization of spectrum opportunities in GSM900 downlink bands, for fixed and mobile scenarios. A testbed to analyze coexistence between the licensed GSM900 downlink system and an OFDM based secondary system that opportunistically shares the same spectrum is presented. Coexistence analysis is based on metrics such as spectrum collisions rate and the secondary system throughput. Using this testbed a cognitive mechanism to classify and select stable opportunities is evaluated in realistic scenarios.
