Base Station
The hardware of a transponder and base station looks like the same. The
only difference is the configuration software. The transponder organizes
the measurements. It allocates time slots to the base stations to identify
when these stations are allowed to start with a measurement.
2.4.2 Group-ID (GID)
A system is identified clearly by its group number. All stations in one system have the same
group number. If there is used a second, a third or more systems in your environment, all
additional systems must have then a different group number (see Figure 5).
2.4.3 FSK Channel (FSK)
The measurement of the round trip of flight (RTOF) happens in a frequency band width of
5,725 to 5,875 GHz. In this band width the LPR
®
system gets a frequency channel. 18
frequency channels are available. All stations in one LPR
®
systems have the same
frequency channel.
If there are more LPR
®
systems in your environment each further LPR
®
system has another frequency channel (see Figure 5).
If you commission the system with the LPR
®
commissioning tool LPR
®
1D
Wizard you cannot choose the frequency channel. The frequency channel
is linked to a group ID. Therefore it is really important to use different group
IDs for different LPR
®
systems.
