C4.1 - Low-Cost Spectrum Analyzer for Cognitive Radio Applications and Coexistence Management in the 2.4 GHz ISM-Band

R. Hornung, R. Heynicke & G. Scholl
Interferences between wireless systems have to be avoided, if multiple wireless systems shall operate simultaneously and in a reliable way in the 2.4 GHz ISM-band. This can be achieved, e.g. by intelligent cognitive radio systems or frequency planning strategies. A cognitive radio or an efficient coexistence management scheme requires a spectrum analyzer. In this article, a fast and low-cost spectrum analyzer will be introduced, which is based on a wireless gateway for sensor/actor communication with...
