3.2.4 Reading distance in the application system
The effective distance which a reader reads a tag is related to many factors.
Including but not limited to the following conditions:
 Reader power. In theory, the greater the power, the farther the effective
distance of reading the tag.
 Tag. Tags of different types, sizes, and production qualities have different
reading distance.
 Reader or tag installation environment. When the reader is in an
electromagnetic wave reflective environment or the tag is mounted on a
different material surface, the read distance of the reader varies.
 Read and write operations. The write operation of the reader requires more
power than the read operation, so the write operation distance is much closer
than the read operation distance. The following figure shows the read/write
distance comparison of the tags in the reader antenna field.
Fig 3.2.4 Distance comparison
Therefore, the installation environment of the reader is as close as possible to
the implementation specification,so as to improve the reliability and
effectiveness of the reader reading the tag. On the other hand, adjacent readers
should be kept above the minimum safe distance and properly adjust the reader
transmit power to reduce mutual interference between readers.
Note: This table is only used as a reference for testing specific tags in an
ideal environment. More specific requirements depend on the field
application environment.
