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着新兴的频谱危机。FCC最近允许未经许可的设备在电视频段上运行，从而产生了认知无线电网络（CRN）。有人认为，CRN导致与电视广播公司的技术和经济冲突，电视广播公司拥有电视频谱的许可证。在这个项目中，CRN被认为是广播公司的商业机会。寻求以下问题的答案：“广播公司利用电视白色空间提供低成本互联网和网络电视服务在经济和技术上是否可行？“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提供低成本的互联网接入和局域网功能。Cog-TV被分配最佳频谱感测时间表，以通过新颖的邻里守望概念提供服务差异化能力。动态定价技术的发展与高峰时间需求负荷分配的目标。此外，还分析了在城市和农村地区建设Cog-TV基础设施的成本，以确定其经济可行性。通过这种架构，广播公司可以利用他们的渠道所有权，以创造竞争优势。从这项研究的结果，预计将使变革和经济上可行的CRN开发和管理方法。Cog-TV概念有可能为大量美国家庭带来负担得起的互联网服务，并通过在新电视机中创造利基市场来影响消费者市场。
