    Rohde & Schwarz and MediaTek have verified new location-based services (LBS) features for 5G new radio (NR), which are now available on the R&S TS-LBS test solution.

    The features will improve emergency caller location and support LBS-related use cases in challenging indoor and outdoor environments with both satellite-based and terrestrial technologies. The R&S TS-LBS now support these and other 3GPP Release 16 network-based positioning features.

    A 5G chipset from MediaTek also has been verified for Release 16, which ensures the chip’s  positioning features.

    The two companies verified the NR positioning reference signals (NR-PRS), which are central to network-based positioning features such as round-trip time (RTT), time difference of arrival in uplink and downlink (UL- TDOA and DL-TDOA), or angle of arrival and departure (AoA and AoD), and which meet the 5G requirements for indoor and outdoor positioning use cases.

    With R&S TS-LBS supporting these features, mobile device and chipset manufacturers as well as test houses and network operators can carry out verification for GCF, PTCRB and network-operator certification using a single test solution.

    About the R&S TS-LBS System

    The R&S TS-LBS is a test system for testing GNSS and network-based positioning. It consists of an R&S CMX500 OBT one-box signaling tester as the network simulator and an R&S SMBV100B GNSS simulator.

    The R&S CMX500 OBT setup provides full network simulation capabilities including the support of multiple 4G or 5G cells at a time. In addition, it provides LBS assistance data to the DUT while the R&S SMBV100B simulates the GNSS satellites.

    The R&S TS-LBS test system can be used for pre-conformance tests and to obtain GCF and PTCRB certification as well as network-operator-specific certification acceptance and validated tests.

    “Adding network-based positioning features such as DL-TDOA based on NR-PRS to the existing satellite based location signals shows the advanced level of our test solution,” said Christoph Pointner, senior vice president, Mobile Radio Testers, Rohde & Schwarz. “We are happy to continue our collaboration with MediaTek to push 5G location-based services further for 3GPP Release 16.”

    Rohde & Schwarz adds an extension to its R&S TS-LBS location-based services test system to meet 112 emergency-call regulations for smartphones

    A new regulation requires all smartphones sold in the European Union from March 2022 onwards to support caller location for 112 emergency calls. To ensure this feature, the devices must be compliant with several positioning systems as outlined by the European Commission.

    In response, Rohde & Schwarz has added an extension to its R&S TS-LBS location-based services test system. Certification service provider CETECOM has already started E112 testing using these test sequences.

    All smartphones sold in the European Union have to be compliant as of March 17 with the Delegated Regulation (EU) 2019/320. A supplement to Radio Equipment Directive (RED) 2014/53/EU, it defines that 112 emergency calls provide caller location information to emergency services in a fast and accurate way, to make sure first responders can arrive at the site of an accident quickly.

    Instead of a harmonized standard, a guideline document from the European Commission recommends the testing procedures for Notified Bodies, who support the smartphone vendors in the conformance assessment procedure. Compliance with Galileo, advanced mobile location (AML) and Wi-Fi positioning will be mandatory.

    The software-based extension to the R&S TS-LBS location-based services test system makes it a tailored solution in line with the European Commission’s guideline document and the upcoming ETSI standard TS 103 825 for AML protocol testing.

    In the Rohde & Schwarz solution, the cellular network is emulated by the R&S CMW500 wideband radio communication tester, while the dual-frequency E1+E5 GNSS Galileo signal is generated by an R&S SMBV100B vector signal generator. Thanks to the automation software of the test setup, all the test cases described in the EC guideline can be executed automatically to ensure unified, fast and repeatable results.
