Antenna spacing with portal configuration
In the portal configuration, multiple antennas are connected to one reader. In this case, the
antennas must not exceed the maximum distance to one another.

Portal spacing of up to 10 m is possible. The probability of a read must be checked.
4.3.6 Read and write range
The read/write range between the reader/antenna and the transponder is influenced by the
following factors:
Table 4- 3 Factors on the read/write range
Factors
Description
Transmit power of the reader The higher the transmit power of the reader, the larger the
reading range.
Transponder size and design The larger the transponder 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.
Manufacturing quality of the tran-
sponders
The better the transponder has been matched to the oper-
ating frequencies during manufacturing, the greater the
reading range.
