Oct. 20, 2006—The following are news announcements made during
the week of Oct. 16.
Reva and Impinj Release European
RFID Performance-Test Results
Reva Systems, an RFID network infrastructure provider
headquartered in Chelmsford, Mass., and
Impinj, a Seattle-based semiconductor and RFID technology
provider, have released the results of tests conducted at an operational
distribution center in Unna, Germany. The jointly conducted tests were a
follow-up to multi-vendor RFID technology demonstrations conducted by
European
Telecommunications Standards Institute Electromagnetic Compatibility and Radio
Spectrum Matters Task Group 34 (ERM TG34) to improve the performance of RFID
reader deployments in Europe (see
ETSI
Tests Show EPC Scaleable in Europe). In the latest round of tests, tag-read
performance was measured as 36 pallets holding more than 2,200 tagged,
real-world consumer goods were loaded and transported through 36 adjacent
loading-dock doors onto docked trucks. All of the RFID tags were powered by an
Impinj Monza Gen 2 chip, while each dock door was monitored by Impinj Speedway
RFID readers, all centrally controlled by a single Reva Tag Acquisition
Processor (TAP) appliance operating in conjunction with a Reva centralized LBT
Sensor. The system complied with proposed ETSI "Listen Before Talk" (LBT)
requirements. Tags passed through the reader antennae's field-of-view for
roughly 1 to 1.5 seconds, and the runs were repeated several times. The tests
demonstrated tag-read rates averaging between 98 and 99 percent in a
dense-reader environment. Previous European trials supported fewer simultaneous
readers, with lower inventory reliability reported.
