Reading range
The reading range between the reader (antenna) and the transponder is affected by the
following factors:
The reading range depends on
Description
Transmit power of the reader
The higher the transmit power of the reader, the larger the
reading range.
Tag size and type
The larger the tag antenna, the larger the power input area
and therefore the larger the reading range.
Absorption factor of the materials
The higher the absorption of the surrounding material, the
smaller the reading range.
Antenna amplification
The bigger the antenna amplification, the larger the reading
range.
Production quality of the tag
The better the tag has been matched to the operating
frequencies during manufacturing, the greater the reading
range
Reflection characteristics of the
environment
In a multiple-reflection environment, the reading range can
be significantly higher than in a low-reflection environment.
