SBIR Phase II: Programmable, Scalable Wireless Information Infrastructure

这个小企业创新研究（SBIR）第二阶段项目有两个主要目标：继续在第一阶段项目中开始的集群软件无线电技术的研究和开发，并使用该技术将当前的波形实现扩展到功能齐全的基站。集群软件无线电的一个高影响力应用是针对蜂窝电话基站，将它们从固定的硬件设备转变为灵活的软件设备，可以支持多种商业标准和公共安全需求。该二期项目将开发一个集群软件无线电基站，与商用GSM移动设备和交换中心进行互操作。目标是建立一个具有足够功能的基站，以便在实地试验中部署，这是使该技术商业化的必要下一步。该项目将包括时序控制、宽带综合和集群内数据传输方面的创新技术开发。在电信行业，许多人预测第三代无线系统的基站将是软件无线电或软件定义无线电。Vanu公司为该市场开发的集群软件无线电技术将提高互操作性，改善对服务不足的农村地区的服务，使射频（RF）频谱的使用更有效，提供实质性的公共安全效益，并加快无线通信市场的技术创新步伐。此外，该公司的计算架构在无线行业之外的信号处理问题上有广泛的应用。

This Small Business Innovation Research (SBIR) Phase II project has two primary objectives: to continue the research and development of clustered software radio technology begun in the Phase I project, and to use that technology to extend current waveform implementations to a fully functional base station. A high impact application of clustered software radio is for cellular telephone base stations, changing them from fixed hardware devices into flexible software devices that can support multiple commercial standards and also public safety needs. This Phase II project will develop a clustered software radio base station that interoperates with commercial GSM mobile units and switching centers. The goal is a base station sufficiently functional to be deployed in a field trial, which is the necessary next step in commercializing the technology. The project will include innovative technology development in timing control, wideband synthesis, and intra-cluster data transport.In the telecommunications industry, many foresee that base stations for third-generation wireless systems will be software radios or software-defined radios. The development of clustered software radio technology by Vanu, Inc. for this market will improve interoperability, improve service to underserved rural areas, enable more efficient use of the radio frequency (RF) spectrum, provide substantial public safety benefits, and increase the pace of technological innovation in the wireless communication marketplace. Moreover, the firm's computing architecture has broad application to signal processing problems outside the wireless industry.
