Gemalto, a Thales company, is using test equipment from
T&M specialist Rohde & Schwarz to ensure that Cinterion IoT modules
operate synchronously across all networks and conditions. This reduces
extensive real network drive tests in different countries for manufacturers of
IoT (Cat M and NB IoT) solutions, resulting in faster time-to-market.
Rohde & Schwarz and Gemalto are working on
significantly reducing expensive and time-consuming drive tests. IoT protocol
stack features have been specified by 3GPP, but IoT devices have to interact
with different network configurations worldwide. This makes it important to
ensure that these features are working well in all sorts of configurations,
configured by different network operators.
Thanks to the current cooperation, manufacturers of IoT
solutions can use virtual drive tests during the development phase of CAT M1
and NB IoT modules to find and fix problems at an earlier stage. This also
enables seamless cellular coverage and reliable connectivity before the
integration process continues and further field tests are performed.
Network-specific integration tests and field tests include analysis of unique
network configurations in different countries, challenging RF Power level
conditions and verification of signaling under compelling RF environments.
The setup consists of R&S Field-to-Lab wireless
communication test system, R&S CMWcards smart network emulator, R&S
CMW500/CMW290 wideband radio communication tester from Rohde & Schwarz. The
successful LTE based R&S Field-to-Lab solution by Rohde & Schwarz has
now been extended to support LTE-M and NB-IoT technologies. With the same user
interface, customers can seamlessly move between LTE and IoT testing. The
simple process of loading the field logs, extracting the required information
from the field log and generating R&S CMWcards test script helps to
replicate the real network environment in a lab with just a few mouse clicks.
The R&S Field-to-Lab supports 3GPP IoT features.
Unlike other simulated drive test solutions, it is also the first virtual drive
test solution for IoT offering replication of signaling and RF conditions in an
easy-to-operate GUI on the R&S CMW500 and R&S CMW290 mobile radio
