Assigned antennas
In the "Assigned antennas" area, you can assign each read point 1 to 4 antennas depending
on the connected reader type. To do this, select the check boxes of the relevant antennas in
the list. If an antenna has already been assigned to a read point, a green icon is displayed
on the right. If the check box is enabled, the antenna is assigned to the selected read point.
To specify antenna parameters for the individual antennas, select the required antenna in
the list.
Table 7- 5 Description of the antenna parameters
Parameter
Description
Description Input box for storing device-specific information.
For example, the location of the antenna
Radiated power Required radiated power that the antenna should output.
Note: The unit (ERP/EIRP) depends on the selected radio profile.
The two input boxes are linked together. If the value in one of the input boxes
is changed, the value of the other input box will be adapted automatically. The
actual radiated power emitted may be lower due to other components and/or
parameters.
Value range
5 ... 33/36 dBm
3 ... 2000/4000 mW
Increment
0.25 dBm
--
Gain The antenna gain affects the actual radiated power.
The gain of an antenna describes how much of the power fed in can be con-
verted in the air and depends on the antenna being used. Here, you can either
select an antenna based on its name or enter the value of the antenna gain of
an antenna being used directly.
Value range
-15 ... 15 dBi
Increment
0.25 dBi
Cable loss The cable loss affects the actual radiated power.
The cable loss depends on the cable being used. Here, you can either select a
cable based on its name or enter the value of the cable loss of a cable being
used directly.
Value range
0 ... 63.75 dB
Increment
0.25 dB
Apply parameters to
all antennas
Button that transfers the entered values (radiated power, gain, cable loss) of
this antenna to all other antennas.
Effective
radiated power
The actual radiated power is made up of the transmit power emitted by the
reader, the cable loss and the antenna gain. It is possible that the target value
for the radiated power is never reached in reality due to the use of long cables
and antennas with low gain.
Note: The unit (ERP/EIRP) depends on the selected radio profile.
