Collaborative Research: Cog-TV: Business and Technical Analysis of Cognitive Radio TV Sets for Enhanced Spectrum Access

由于需求的增加，当今的无线网络正面临着新出现的频谱危机。美国联邦通信委员会最近允许未经许可的设备在电视频段内运行，从而产生认知无线电网络（crn）。有人认为，crn与拥有电视频谱许可证的电视广播公司在技术和经济上存在冲突。在这个项目中，crn被认为是广播公司的商机。寻求以下问题的答案：“广播公司利用电视空白空间提供低成本的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，考虑了认知无线电功能电视机（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被分配了最佳的频谱传感时间表，通过一种新颖的邻里监视概念提供服务差异化能力。动态定价技术的发展目标是分配高峰时段的需求负荷。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频道所有权来创造竞争优势。这项研究的结果有望使变革性和经济上可行的CRN开发和管理方法成为可能。Cog-TV的概念有潜力为大批美国家庭提供负担得起的互联网服务，并通过在新电视机上创造一个利基市场来影响消费市场。

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.
