RFID, or Radio Frequency Identification, can be a confusing field for
those starting to learn about the technology. RFID comes in many
different flavors, but an easy entry point from which to grasp RFID
technology is to first look at frequency. In physics terms, frequency is
the number of complete wave cycles passing a point in a second. This
post will focus on ultra high frequency, or UHF, systems (433 MHz,
860-960 MHz). These systems are known for generating long read ranges
relative to other operating frequencies.
In every UHF RFID system, there are four basic components:RFID system
RFID Reader
Cable
Antenna
Rfid UHF label
Of
all these components, the RFID tag varies the most and significantly
impacts the overall success of the system. Form factors, price ranges,
read ranges, attachment methods, etc. can make finding the best tag for
the job a little daunting. When selecting the right RFID tag for your
system, we have identified some core differences between UHF tags.
Unlike
barcode paper label, each UHF RFID label contains a small IC chip and
antenna for tracing of the tagging asset automatically. From this point
of view, it helps to improve the reliability and security in the
inventory control processes. And at the same time, with this UHF label
glued to the files or parcels, possibilities of misplacing assets or
losing assets will be prevented.
The housing material of the UHF
label antenna is aluminum, making it durable even under harsh
environment. To be exact, it can survive in the extreme temperatures, as
low as -40 Celsius degree, or as high as +90 Celsius degree. Besides,
read and write range varies from 1 meter to 10 meters basing on
different readers and environment.
