Game Changing 99+% Accurate Directional RFID Portal Integrated with Wide-Area IoT Analytics

迄今为止，在工业、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，但价格昂贵，而可靠地检测便宜的紧凑和超薄无源（无电池）标签是困难的，特别是在超过2-3米的距离上。剑桥大学的子公司PervasID已经开发出了一种强大的专利产品，可以使用固定的基础设施在广泛的区域内高度可靠地读取标准的现成无源RFID标签\[1\]。这项技术已被英国和欧洲的主要零售商、航空航天制造公司、欧盟、美国和亚洲的集成商以及全球各地的医疗保健提供商（包括NHS）安装，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。A <1% error rate is achieved even for densely packed devices. This technology is now generating sales revenues of \>£1M per year to major companies such as Stanley Black & Decker.Although PervasID is confident that its patented technology is technically world leading, we have identified the need to enhance the wide-area system architecture to provide virtual wireless boundaries with highly accurate bidirectional movement information at portals. We have identified a solution to achieve this using a combination of steerable tag suppression technology with data analytics that will achieve very high accuracy even for a large number of tags. Analysis by potential customers has shown this could reduce stock shrinkage by around £100,000 per annum per facility. The new solution will aim to deliver an ROI of just 1 year for customers such as this and allow PervasID to address much larger markets.A successful project will enable PervasID to build the RFID systems (via OEM agreements), which will be sold to end customers and system integrators along with other services such as data analytics, installed system design, installation support, service and operational support.\[1\] S.

To date, the tracking of individual products and components in applications such as industrial, 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 (battery free) 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 that enables highly reliable reading of standard off-the-shelf passive RFID tags over wide areas, using a fixed infrastructure \[1\]. This technology has been installed by major UK & European retailers, Aerospace manufacturing companies, EU, US and Asian integrators and healthcare providers (including 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.
