2.2.12 Data Tests
The NB-IoT signaling application provides a test mode, using only layer 1 and 2 of the
protocol stack. And it provides a data application mode that supports also layer 3.
To use the data application mode, you need the following options in addition to the
"NB-IoT signaling" application:
●
Data application unit (DAU, R&S CMW-B450x, mandatory)
●
IPv4 enabler (R&S CMW-KA100, mandatory)
IPv6 enabler (R&S CMW-KA150, optional)
●
DAU measurements (R&S CMW-KM050, optional)
●
Installed DAU software package
Configure a scheduling type with uplink and downlink scheduling. You can use user-
defined scheduling with alternating UL/DL pattern.
In data application mode, you can perform IP-based data tests using the DAU mea-
surements.
For further reference:
●
To enable the data application mode, see "Connection Type" on page 72.
●
For step-by-step instructions, refer to the data application unit documentation.
2.2.13 Trigger Signals
The NB-IoT signaling application provides trigger signals that can be used by other
R&S
CMW applications to synchronize to the generated NB-IoT downlink signal.
To address the trigger signals in remote commands, use the following strings, with <i>
replaced by the instance number of the signaling application:
●
"NB-IoT Sig<i>: NPUSCH format 1 Trigger"
●
"NB-IoT Sig<i>: NPUSCH format 2 Trigger"
●
"NB-IoT Sig<i>: NPRACH Trigger"
