ThingMagic M6e User Guide

•
Application Surface: Some materials, including metal and moisture, interfere with tag performance. Tags
applied to items made from or containing these materials may not perform as expected.
•
Tag Orientation: Reader performance is affected by the orientation of the tag in the antenna field. The
ThingMagic antenna is circularly polarized, so it reads face-to but not edge-to.
•
Tag Model:
Many tag models are available, each with its own performance characteristics.
Multiple Readers
•
The reader adversely affects performance of 900 MHz devices. These devices also may degrade
performance of the reader.
•
Antennas on other readers operating in close proximity may interfere with one another, thus degrading
performance of the readers. If antennas from different readers are facing each other, they should have
opposite polarity for best performance (e.g., right-hand polarized antenna facing a left-hand polarized
antenna).
•
Interference from other antennas may be eliminated or reduced by using either one or both of the
following strategies:
•
Affected antennas may be synchronized by a separate user application using a time-
multiplexing strategy.
•
Antenna power can be reduced by reconfiguring the RF Transmit Power setting for the reader.
NOTE: Performance tests conducted under typical operating conditions at your site are recommended
to help optimize system performance.
