Dave Cavalcanti, Monisha Ghosh
2008 2008 3rd International Conference on Cognitive Radio Oriented Wireless Networks and Communications (CrownCom 2008)  
In this paper, we discuss the regulatory scenario for cognitive radio networks and give an overview of the emerging IEEE 802.22 standard, which is based on a dynamic spectrum access model, and provides new opportunities for wireless broadband access in rural area and remote communities. We discuss the main design challenges for the shared spectrum access model and describe how they are being addressed within the scope of the 802.22 networks. Some of the key design issues include incumbent
