Rohde & Schwarz and CommSolid have successfully completed the verification of 3GPP Release 14 location services (LCS), which is one of the new positioning technologies for NarrowBand-IoT (NB-IoT). The Cat-NB2 verification was performed with CommSolid's NB-IoT modem solution against the R&S CMW500 mobile communication tester. The R&S Location Based Services (LBS) solution based on R&S CMWcards GUI, a subset of TS-LBS, allows the verification of chipsets and mobile devices for mobile manufacturers, chipset manufacturers, test houses and network operators with the target to get permission to operate them in a particular network.
The successful NB-IoT location services verification of the CommSolid NB-IoT modem using the Rohde & Schwarz test solution marks an important milestone in IoT positioning and navigation. The R&S CMW500 mobile communication tester equipped with the R&S CMWcards LBS solution and the CommSolid NB-IoT modem form the first test platform to offer verification of Cat-NB2 location services.
R&S CMWcards supports location-based services testing of 3GPP Release-14 NB-IoT devices. The software runs on a R&S CMW500 which acts as a base station simulator for several cells. The device under test (DUT) observes the time difference of arrival (OTDOA) of the simulated cells and reports it to the serving cell, which is also simulated by the R&S CMW500. The R&S CMW500 calculates the position of the DUT by using the reported OTDOA measurements and sends the position coordinates back to the DUT. This R&S LBS solution based on R&S CMWcards is able to provide R&D as well as GCF and PTCRB pre-certification for chip sets and mobile devices.
At MWC 2018, Rohde & Schwarz will showcase this first test solution for Cat-NB2 LBS based on the R&S CMW500 with R&S CMWcards and CommSolid's NB-IoT modem.
