This Small Business Technology Transfer (STTR) Phase II project will involve research on and development of a reconfigurable wireless platform enabling broadband communications in rural areas via secondary access of television white spaces (TVWS) spectrum. The recently ratified IEEE standard, 802.22, is the most promising technique proposed for TVWS operation. Unfortunately, current 802.22 implementations create unacceptable levels of out-of-band (OOB) emissions, greatly degrading the performance of both primary and secondary TVWS users. Current designs also fail to sense the presence of other TVWS users as necessary for coexistence. Such limitations have prevented the rollout of 802.22 solutions. The proposed work overcomes these limitations, leading to a low-cost, high throughput, and robust implementation for the 802.22 wireless regional area network (WRAN). Phase II laboratory and field testing will validate the viability of Phase II developed 802.22 WRAN prototype devices for rural broadband deployment. The activities described in this proposal will significantly advance the community?s understanding of methods to make cognitive radio networks such as 802.22 practical and effective in offering broadband services in rural areas.The broader impact/commercial potential of this project centers on offering a low-cost broadband solution to the 14.5 million Americans who live in rural areas currently beyond the reach of broadband access, while appealing to those in rural areas that have broadband access but are unable to afford the high equipment and service costs of current solutions. Rural communities with broadband access have lower unemployment, higher per capita earnings, and greater educational opportunity. Broadband improves rural area healthcare effectiveness while lowering cost. Public safety, emergency service, and first responder communities also call for high data-rate communications to better predict and respond to natural disasters.

这一小型企业技术转让(STTR)第二阶段项目将包括研究和开发可重新配置的无线平台，通过电视白空间(TVWS)频谱的二次接入实现农村地区的宽带通信。最近批准的IEEE标准802.22是最有前途的电视视听操作技术。不幸的是，当前的802.22实施造成了不可接受的带外(OOB)排放水平，极大地降低了主要和辅助TVWS用户的性能。目前的设计也没有意识到其他TVWS用户的存在是共存所必需的。这些限制阻碍了802.22种解决方案的推出。建议的工作克服了这些限制，为802.22无线局域网(WRAN)带来了低成本、高吞吐量和健壮的实施。第二阶段实验室和现场测试将验证第二阶段为农村宽带部署开发的802.22个WRAN原型设备的可行性。此提案中描述的活动将显著促进社区-S对使认知无线电网络(如802.22)在农村地区提供宽带服务的方法的实用和有效的理解。该项目的更广泛影响/商业潜力集中在为生活在目前宽带接入范围之外的农村地区的1,450万美国人提供低成本宽带解决方案，同时吸引那些拥有宽带接入但无法负担当前解决方案的高昂设备和服务成本的农村地区的人。有宽带接入的农村社区失业率较低，人均收入较高，受教育机会较多。宽带提高了农村地区的医疗效率，同时降低了成本。公共安全、紧急服务和急救人员社区也呼吁进行高数据速率通信，以更好地预测和应对自然灾害。
