Multi-service Digital Distributed Antenna System
项目介绍
来自剑桥大学的研究人员已经开发出克服的室内无线信号传播先进天线系统，有助于克服3G和LTE的电流限制，为数字信号处理提供解决方案。大型建筑，如商场，机场最需要改进的建筑物内无线覆盖，需要安装分布式天线系统（ DAS ）需要专用高规格的基础设施，如光纤，高线性度和动态范围设备等，并需要高能量消耗。毫微微蜂窝基站可以解决这些问题，但仍仅限于单一的服务和固定配置。
数字DAS （ DDAS ）解决反感，能够压缩数据信号，从而减少对基础设施的带宽要求，最终实现使用铜而非光纤和也允许多个服务（语音，数据，视频...... ）合并到一个单一的基础设施上。采用DDAS还能够拥有更灵活的体系结构，包括每个服务或每个流可重构性和在多个建筑物共用一个共同的基础设施。

Researchers from the University of Cambridge have developed a digital signal processing solution which overcomes the current limitations of in-building wireless signal propagation for advanced services such as 3G and LTE. Most large buildings requiring improved in-building radio coverage, such as shopping malls and airports, are installing Distributed Antenna Systems (DAS) which require dedicated high-specification infrastructure such as optical fibre, high linearity and dynamic range, and suffer from high energy consumption. Femtocells provide an alternative solution which avoid some of these issues but are still restricted to single service and fixed configurations.
The proposed digital DAS (DDAS) solution substantially compresses the data signals thereby reducing the infrastructure bandwidth requirement ultimately towards use of copper rather than optical fibre and also allowing multiple services (voice, data, video…) to be combined onto a single infrastructure. The use of DDAS also enables more flexible architectures, including per-service or per stream reconfigurability and remote service distribution for multiple buildings over a common infrastructure. This would allow easier upgrade and secure maintenance using software rather than the current hardware approach.
We are now looking for industrial partners to help us develop this technology further to exploit the exciting market opportunity which this technology presents.
