NgTechno and Tempo Certo Cronometragem-Race Timing with WaveLabs all based in Sao Paulo, Brazil, are offering race-timing solutions for running events and recently completed the design of their own RFID timing hardware, the WL4i. The new device is based on ThingMagic’s Mercury-6e module and among other critical features offers four antenna ports, Wi-Fi, and optional 3G cellular communication. The device can be purchased in a weather-resistant portable box for easy deployment at race events.

Upon completion of the design, NgTechno decided to compare the new M6e-based product against their earlier solution based on the Speedway Revolution R420, designed and manufactured by Impinj. On September 19th, 2012 the company timed the 5-mille Valinhos running race in Campinas, an industrial city located about 100km north-west of Sao Paulo. In this event and a number of others, rather than deploying a single system, the engineering team set up two completely independent systems: one system used the Impinj R420, the second system used the WL4i with the integrated Mercury-6e.
During the Valinhos race the WL4i/M6e collected a total of 5,333 tag reads, compared to 4,063 reads collected by the Impinj Speedway R420. At the start line, the WL4i/M6e successfully identified 439 individual tags, versus 436 individual tags identified by the R420. At the finish line, both devices identified 438 individual tags. In summary the WL4i/M6e outperformed the R420 in terms of total number of tag reads and hence overall system margin. The WL4i/M6e also outperformed the R420 in terms of the very important metric of uniquely identified tags at the start and finish lines.
