Com o rápido uso das comunicações sem fios em âmbitos pessoais, comerciais e governamentais, a utilização eficiente do espectro tornou-se um tema de grande interesse. A maioria das bandas licenciadas sofre de subutilização e menor ocupação do espectro. A tecnologia de rádio cognitivo promete ser uma solução para o problema da baixa ocupação do espectro e da utilização ineficiente do espectro de rádio licenciado. Um dos principais componentes da tecnologia de rádio cognitivo é a deteção do espectro. A deteção de energia (ED) é uma das técnicas populares de deteção do espectro para o rádio cognitivo. Neste trabalho, propus o stick RTL 2832U SDR como adequado para o método de deteção de espectro baseado na deteção de energia. Nesta experiência, capturamos o sinal em tempo real proveniente da BTS em diferentes cidades em áreas rurais e urbanas usando um stick RTL 2832U SDR para decidir se a banda de frequência está disponível ou não. O software GNU Radio permite a implementação da técnica de deteção de espectro por deteção de energia usando o RTL-SDR.
