Dynamic Spectrum Access: regulations, standards and green radio policy considerations

Abstract

Dynamic spectrum access (DSA) technologies are increasingly viewed as a potential solution to improve overall spectral utilisation efficiency and for bridging the digital divide in the rural areas. In particular, DSA technologies have the ability to sense and opportunistically access radio frequency (RF) spectrum that lies fallow at any particular time or space. However, in order to achieve successful deployment of these technologies, spectrum regulators need to implement reforms to their existing spectrum management regulations. In this context, this paper investigates conventional and emerging RF spectrum regulations and standards necessary to realise maximum benefits that such technologies might bring. In addition, this paper considers the ever-growing negative environmental impact caused by the information and communication technologies (ICT) sector. The paper suggests that any new dynamic spectrum management regulations should go hand-in-hand with the promotion of green communications networks policies.
