WESTMINSTER, Colo., July 14 /PRNewswire/ --
-- A study published last week in the Journal of the American Medical
reported that RFID systems can cause "potentially hazardous incidents
in medical devices" used in hospitals. Unfortunately, the report
ignores mainstream passive RFID readers in favor of an uncommonly
high-powered RFID reader used at an uncommonly close distance.
-- SkyeTek, Inc. (http://www.skyetek.com), a leading provider of passive
RFID reader technology, sees the study as making a strong case for the
upper limit of passive UHF output power (2 - 4 Watts) around medical
devices. However, it is important to note the study does not test for
today's most common passive UHF use cases which call for RFID reader
output power anywhere from 0.25 Watt to 1 Watt, the maximum allowed by
the FCC. By comparison, one of today's most popular cell phone models
emits 1.59 Watts.
-- The study also ignores the HF frequency entirely which comprises a
substantial, if not the largest, portion of passive RFID technology
used in hospitals today. The potential EMI coming from passive HF RFID
readers is significantly less than that coming from their UHF
-- The passive UHF RFID reader used in the study is an unrepresentative
product used unconventionally.
-- Although the reader model was not specified in the study, it is most
likely the Feig ID ISC.LRMU2000 Fixed UHF Long Range Reader Unit
which has a maximum of 3 Watts of output power. The vast majority
of passive UHF RFID readers sold toda
