Within the TINA project, Cambridge University has demonstrated the feasibility of using low cost UHF RFID technology in a new way to provide (i) enhanced tag read range (to >10m), (ii) increased (100%) tag reading probability and (iii) the ability to locate the passive tag to approximately 1m resolution. This has been achieved by combining a customised RFID reader with a distributed antenna system. The ability to use the distributed antennas in a collaborative manner acts to remove the effect of radio propagation fades and also has allowed the development of algorithms, which have been implemented on RFID firmware, to take the RF information from the individual antennas and use this to generate the location information. The TINA project resulted in two ongoing patent applications to protect the concepts described above.These enhancements to passive UHF RFID have generated a great deal of interest, both in an academic sense - we have presented the results in invited papers and a keynote at 5 international conferences - but also commercially across a variety of sectors. The PULSE project therefore seeks to further the commercialisation of the technology. It will do this via (i) building a prototype system suitable for demonstration to customers and (ii) working with commercial partners to understand better the market opportunities and, concentrating on the retail sector, develop an application demonstration based on the prototype location system and field trial this approach. This twin pronged approach will allow the identification of the best route to commercialisation and, working in collaboration with MBA students from the Judge Business School, will result in business plans to map this route forward.

在TINA项目中，剑桥大学已经证明了以一种新的方式使用低成本UHF RFID技术的可行性，以提供(I)增强的标签读取范围(至&gt；10米)，(Ii)提高(100%)标签读取概率和(Iii)定位无源标签到大约1米分辨率的能力。这是通过将定制的RFID读取器与分布式天线系统相结合来实现的。以协作方式使用分布式天线的能力起到了消除无线电传播衰落的影响的作用，并且还允许开发已经在RFID固件上实现的算法，以从各个天线获取RF信息并使用该信息来生成位置信息。TINA项目导致了两项正在进行的专利申请，以保护上述概念。这些对无源UHF RFID的增强引起了极大的兴趣，不仅在学术上--我们在5个国际会议上的特邀论文和主题演讲中展示了结果--而且在商业上也在不同的领域。因此，PULSE项目寻求进一步推动该技术的商业化。它将通过(I)建立一个适合向客户演示的原型系统和(Ii)与商业合作伙伴合作，更好地了解市场机会，并将重点放在零售业，开发基于原型定位系统的应用演示，并对这种方法进行现场试验。这种双管齐下的方法将使我们能够确定实现商业化的最佳路线，并与佳奇商学院的MBA学生合作，制定商业计划，规划未来的商业化路线。
