Today's wireless networks are facing an emerging spectrum crisis due to increased demand. FCC has recently allowed non-licensed devices to operate in the TV spectrum band, leading to cognitive radio networks (CRNs). It is argued that CRNs result in a technical and economical conflict with the TV broadcast companies, which own licenses to the TV spectrum. In this project, CRNs are considered as a business opportunity for broadcast companies. The answer to the following question is sought: "Is it economically and technically viable for broadcast companies to utilize TV white spaces for low-cost Internet provision and web-enabled TV services?" To facilitate the involvement of broadcast companies in the cognitive radio business, the concept of cognitive radio-enabled TV set (Cog-TV) is considered. Cog-TV provides low-cost access to the Internet and local area network capabilities. Cog-TVs are assigned optimal spectrum sensing schedules to provide service differentiation capabilities through a novel neighborhood watch concept. Dynamic pricing techniques are developed with the objective of distributing the peak-time demand load. Moreover, the cost of building the Cog-TV infrastructure in urban and rural areas is analyzed to determine its economic feasibility. Through this architecture, broadcast companies can leverage their channel ownership to create a competitive advantage.The results from this research are expected to enable transformative and economically viable CRN development and management approaches. The Cog-TV concept has the potential to bring affordable Internet service to a large group of American households and impact consumer market by creating a niche market in new TV sets.

由于需求的增加，当今的无线网络正面临新兴的频谱危机。 FCC最近允许未经许可的设备在电视频谱频段中运行，从而导致认知无线网络（CRN）。有人认为，CRN与电视广播公司造成了技术和经济冲突，该公司将获得电视频谱的许可。在这个项目中，CRN被视为广播公司的商机。寻求解决以下问题的答案：“广播公司在经济和技术上在技术上可行，将电视白色空间用于低成本的互联网提供和支持网络的电视服务？”为了促进广播公司参与认知无线电业务，考虑了认知无线电电视机（COG-TV）的概念。 COG-TV提供了对Internet和本地网络功能的低成本访问。 COG-TV被分配了最佳的频谱传感时间表，以通过新颖的邻里手表概念提供服务差异功能。开发动态定价技术的目的是分配高峰时间需求负载。此外，分析了在城市和农村地区建立COG-TV基础设施的成本，以确定其经济可行性。通过这种架构，广播公司可以利用其渠道所有权来创造竞争优势。这项研究的结果有望实现变革性且经济上可行的CRN开发和管理方法。 COG-TV概念有可能通过在新电视机中创建利基市场来为大量的美国家庭带来负担得起的互联网服务，并影响消费市场。
