Reading range
The reading range between the reader (antenna) and the transponder is affected by the
following factors:
The reading range depends on
Transmit power of the reader
Tag size and type
Absorption factor of the materials
Antenna amplification
Production quality of the tag
Reflection characteristics of the
environment
.
4-10
Description
The higher the transmit power of the reader, the larger the
reading range.
The larger the tag antenna, the larger the power input area
and therefore the larger the reading range.
The higher the absorption of the surrounding material, the
smaller the reading range.
The bigger the antenna amplification, the larger the reading
range.
The better the tag has been matched to the operating
frequencies during manufacturing, the greater the reading
range
In a multiple-reflection environment, the reading range can
be significantly higher than in a low-reflection environment.
