The complexity of wireless networks requires careful design with special attention to energy and bandwidth efficiency. The energy efficiency is of more importance due to increasing penetration of wireless systems in different battery-operated applications as well as more conscious global view on the need for "Greening the Earth". Bandwidth efficiency is very important parameter, because it relates to frequency spectrum, which is naturally scarce resource. Thus spectrum sensing is an important part of "Green Engineering". The "Cognitive Radio" (CR) technology sheds new light on unavailability of spectrum by managing radio resources in more systematic and efficient way. Around the Globe there is a coordinated move for Digital Switch over (DSO) by discontinuing analogue television transmission. This "Digital Dividend" (DD) has created a new spectrum opportunities for many new wireless technologies. We focus on the scope and nature of opportunities for white space created by DD for Indian scenarios. We discuss use cases for the exploitation of Television White Space (TVWS) suitable for rural India based on user's and BS geo-location and user's mobility followed by QoS requirements and recent regulatory activities.
