    Rohde & Schwarz and Huawei conduct field trials for 5G and V2X precision

    Rohde & Schwarz and Huawei have successfully conducted cellular-based 5G V2X latency measurements in vehicular environments in field tests in Munich and Shanghai.

    In a joint project between Huawei and Rohde & Schwarz, a precision end-to-end delay measurement system for over-the-air IP transmissions was applied to 5G V2X communication for cooperative driving applications in field tests in a moving car.

    The precision absolute time standards on both ends were derived from two independent GPS receivers.

    The initial measurements show that it is possible to achieve delays in the millisecond regime in a 5G network, demonstrating superior latency performance in comparison to LTE.

    One of the key use cases of 5G is ultra-reliable low-latency communication (URLLC). Important for advanced vehicle-to-X communication use cases, URLLC will enable automated driving in the future.

    A measurement accuracy below 2 µs for each transmitted IP packet was demonstrated. The transmitted data contained various IP traffic streams including video, lidar and control data (ITS messages) for a tele-operated vehicle.

    While the trial in Munich was related to a tele-operated driving project, the tests in Shanghai were related to a platoon V2X testing site, where a number of vehicles traveling together are electronically connected via wireless communication.

    The delay for transmission of one IP packet from source over-the-air to a (moving) receiver (sink) needs to be measured, spanning all delays introduced by the radio transmitter, propagation delay and radio receiver from/to IP packet level.

    As latency is one of the key performance indicators of 5G and crucial for safety applications, such measurements could become an important criterion for future certification testing.

    “We are delighted to collaborate with Huawei to contribute with our test and measurement expertise to 5G technology development,” said Andreas Pauly, executive vice president,  Test & Measurement at Rohde & Schwarz. “With a strong global footprint in the telco ecosystem and close cooperation with partners, Rohde & Schwarz is committed to further expanding our innovative test and measurement solutions to new automotive applications.”

  • InvenSense licenses inertial navigation tech to Huawei

    InvenSense licenses inertial navigation tech to Huawei

    Huawei has licensed the InvenSense Positioning Library (IPL) software sensor-assisted positioning technology for incorporation into the Kirin 950 mobile application processor platforms by HiSilicon.

    InvenSense is a provider of micro-electro-mechanical (MEMS) sensor platforms. The recently launched Huawei Mate 8 smartphone is the first model to incorporate the HiSilicon and IPL technology.

    IPL improves smartphone GNSS-only implementations by providing more continuous and accurate navigation in areas with poor GNSS signal quality. The IPL solution delivers sensor-enhanced positioning providing a high-availability, high-accuracy turn-by-turn navigation user experience to HiSilicon mobile platforms and mobile application developers.

    Through this collaboration, InvenSense and HiSilicon will make continuous improvements to IPL and the overall location subsystem to provide the best possible navigation experience to Huawei’s customers.

    The combination of sensor positioning with GNSS enhances navigation user experience by eliminating “GPS Signal Lost” warnings and unnecessary re-routings in map applications due to GNSS multipath errors. IPL uses complex algorithms that take sensor data from the mobile device gyroscope, accelerometer, magnetometer and barometric pressure sensors to generate an inertial navigation system (INS) that tracks the position change of a vehicle or pedestrian.

    IPL then combines the INS with GNSS to provide always-available and more accurate location data when GNSS is inaccurate or unavailable, such as in deep urban canyons with tall buildings or in tunnels and parking garages. IPL operates in any physical orientation allowing the user to freely move the phone in the vehicle during active navigation sessions.

    “Today’s consumers are increasingly using smartphones for turn-by-turn navigation in vehicles, creating a strong need for a higher quality user experience that decreases the occurrence of confusing or stressful re-routes and GPS lost signal messages,” said Eitan Medina, vice president marketing and product management at InvenSense. “We are pleased that HiSilicon, a market leader in end-to-end chipsets and solutions, has chosen our IPL technology for integration into its mobile platforms.”

    IPL is available now for smartphones using Android, iOS, Windows and general Linux operating systems.

  • Hexagon and Huawei partner to deliver smart city solutions

    Hexagon AB has entered a strategic partnership with Huawei, an information and communications technology (ICT) company, to deliver smart city solutions.

    With most of the world’s population living in cities, safety and infrastructure challenges are at an all-time high. Hexagon and Huawei are working together to meet this global challenge by integrating Huawei’s communications hardware with Hexagon’s safety and infrastructure software solutions.

    The combined solution improves inter-agency collaboration and leverages big data analytics to better predict, prepare for, and respond to urban area challenges.

    Safety is a primary focus of the combined solution, offering cities connected command centers with integrated systems that maximize efficiencies in all preparedness and response areas. Huawei’s contributions include technologies from its Safe City portfolio such as high-definition video surveillance, broadband trunking and IP-based conference calling systems. Hexagon’s emergency response, utilities management and transportation software solution portfolio, which includes computer-aided dispatch, will provide the visibility and decision-support backbone to enable customers to think and act more nimbly.

    “Huawei’s technologies, expertise and global coverage, especially in emerging market areas, nicely complement our ability to deliver smart city solutions to law enforcement, government, security personnel and other public service agencies around the world,” said Ola Rollén, Hexagon president and CEO.

    “Safety, including efficient response to crisis management, will continue to be a key challenge for urban management, especially in developing economies that are stimulating population movement into these areas,” said Yan Lida, president of Huawei Enterprise Business Group. “Together with Hexagon, the global authority on safety and infrastructure solutions, our extensive ICT technologies that help architect safe city infrastructure will help make societies safer.”
