Passive IoT Platform using 99%+ Accurate RFID Technology

迄今为止，在零售、医疗保健和制造业等应用中跟踪单个产品和组件一直具有挑战性，难以以商业上可行的方式实现。有源（电池供电）标签，虽然允许长读取范围，是昂贵的，而可靠地检测廉价的紧凑和超薄的无源标签是困难的，特别是在超过2-3米的距离。剑桥大学衍生公司PervasID开发了一种强大的专利产品（专利号：EP2564467 A1， EP2564229 A2， US9384376 B2和US9367785 B2），使用固定基础设施[1]，可以在广泛的区域内高度可靠地读取标准的现成无源RFID标签。PervasID技术已被全球主要的英国/欧洲零售商、欧盟/美国/亚洲集成商和医疗保健提供商（包括Harland Simon和NHS）测试了20多次，并被发现优于市场上所有其他被动系统，包括来自英特尔等科技巨头的系统。>即使密集的设备也能达到99%的错误率。尽管PervasID相信其专利技术在技术上是世界领先的，但如果该技术具有广泛的商业潜力，还需要克服各种技术和经济挑战。因此，该项目旨在开发低成本的下一代新型系统架构，具有精确的定位能力和新颖的天线技术，可将硬件成本降低85%。据预测，该产品将带来4-10%的潜在零售销售增长，并减少1-5%的收缩。在医疗保健应用程序等库存安全性方面也可以看到类似的好处。一个成功的项目将使合作伙伴能够建立RFID系统（通过OEM协议），这些系统将与其他服务一起出售给最终客户和系统集成商，如安装系统设计，安装支持，服务和运营支持陈志强，陈志强，“基于宽带无源超高频射频识别技术的射频识别系统”，《电子工程学报》。

To date, the tracking of individual products and components in applications such as retail, healthcare and manufacturing has been challenging to achieve in a commercially viable way. Active (battery powered) tags, although allowing a long-read range, are expensive, while reliably detecting cheap compact and ultrathin passive tags is difficult, particularly over a distance of more than 2-3 metres.PervasID, a Cambridge University spin-out, has developed a robustly patented product (patent numbers: EP2564467 A1, EP2564229 A2, US9384376 B2 and US9367785 B2) that enables highly reliable reading of standard off-the-shelf passive RFID tags over wide areas, using a fixed infrastructure [1].The PervasID technology has been tested more than 20 times by major UK/European Retailers, EU/US/Asian integrators and healthcare providers (including Harland Simon and the NHS) around the Globe and has been found to outperform all other passive systems on the market, including that from technology giants, such as Intel. >99% error rate is achieved even for densely packed devices.Although PervasID is confident that its patented technology is technically world leading, various technological and economical challenges remain to be overcome if the technology is to have wide commercial potential. This project therefore aims to develop a low-cost next generation novel system architecture, with an accurate location capability and novel antenna technology allowing an 85% reduction in hardware costs. The product has been predicted to deliver a potential retail sales uplift from 4-10% and a shrinkage reduction of 1-5%. Similar benefits are seen in inventory security such as for healthcare applications.A successful project will enable the partners to build the RFID systems (via OEM agreements), which will be sold to end customers and system integrators along with other services such as installed system design, installation support, service and operational support.[1] S.
