Positioning Module

Positioning Module Featuring both UDR and ADR Technology u-blox has announced the NEO- M9V global navigation satellite system (GNSS) receiver. The first u-blox positioning receiver to offer both untethered dead reckoning (UDR) and automotive dead reckoning (ADR), NEO-M9V is a perfect fit for fleet management and micromobility applications that require reliable meter-level positioning accuracy even in challenging GNSS signal environments such as urban canyons. Vehicle fleet managers seeking to cut costs and lower their carbon footprint depend on accurate positioning and navigation data to reduce fuel consumption. Additionally, accurate odometry data is key to fleet managers for billing and compliance. Micromobility operators need to accurately locate their devices to service the individual bikes and scooters, as locating vehicles on the wrong side of a street can force drivers to make long detours to reach their intended destination, incurring additional cost, lower service quality, and polluting the air. Accurate positioning is also vital to geofence their operation in compliance with local regulations. Using inertial sensor measurements, UDR offers a smooth navigation experience in dense urban environments by bridging gaps in GNSS signal coverage and mitigating the impact of multipath effects caused by GNSS signals that bounce off buildings. ADR further increases positioning accuracy in demanding environments by including the vehicle speed into the sensor fusion algorithm. Offering both UDR and ADR on the same module delivers maximum positioning performance and design flexibility at once, allowing our customers to provide the best solution caseby-case to each of their endcustomers. NEO-M9V also features dynamic models optimized for both cars and e-scooters. By adapting the algorithms of the dead reckoning solution to the behavior of these use cases, these dynamic models further increase the quality of the position reading. NEO-M9V is based on the u-blox M9 GNSS technology platform. Its ability to track up to four GNSS constellations maximizes the number of GNSS satellites within its line of sight at any given moment. Integrated SAW and LNA filters offer excellent interference mitigation for a robust solution, accelerating product design and shortening time to market. And compatibility with the popular NEO form factor reduces migration efforts for customers upgrading existing designs. IoT Modules offer Out-of-the-Box Secure Connectivity to the AWS Cloud u-blox has announced two modules designed to enable Amazon Web Services (AWS) cloud services for device and fleet management out of the box: the NORA-W2 AWS IoT ExpressLink WiFi module and the SARA-R5 AWS IoT Express- Link cellular module for internet of things (IoT) connectivity. The AWS IoT ExpressLink modules will significantly accelerate design-in and time to market. For many businesses, connecting devices to the cloud remains challenging. Existing solutions involve installing and maintaining dedicated software to manage connectivity on the devices. In addition, many legacy devices are too resourceconstrained to accommodate the additional code required to enable cloud connectivity. To solve these challenges, these two modules were selected by EDN, Inc. for their gardening products: The u-blox AWS IoT Express- Link modules are all about speed and simplicity. Paving the way for rapid design-ins with no complex software to run and maintain on the device side, the modules are ideal for small to mediumsized businesses targeting consumer and industrial markets. Featuring a simplified and highly abstracted command set, the modules can be configured without requiring specialized competencies in IoT product development, networking, and cryptography. Pre-provisioned to communicate with AWS IoT Core, they can connect to AWS securely, out of the box, with a few commands only and integrate with services in the AWS ecosystem. The NORA-W2 AWS Express- Link module is a new u-blox module delivering WiFi 4 connectivity as well as Bluetooth low energy 5 connectivity (including Bluetooth long range). The compact module (10.4 by 14.3 mm) features a powerful dual-core central processing unit (CPU) for advanced customer applications. It is available with an antenna pin or featuring a printed circuit board (PCB) antenna. The SARA-R510 AWS IoT ExpressLink module is a variant of the SARA-R510S LTE-M and NB-IoT module. The power optimized low-power wide-area (LPWA) module consumes less than 1 µA of current in power save mode (PSM), making it ideal for battery-powered applications. The module is certified for multi-regional use. First samples of the u-blox AWS IoT ExpressLink modules and EVKs will be available by Q1 2022. ■ ublox www.ublox.com 50 hf-praxis 2/2022

RF & Wireless Industry First Test for 3GPP Release 16 UE Radio Capability Signaling Optimization Anritsu Corporation is pleased to announce that it has successfully verified RACS feature for 5G New Radio (NR). This industry-first achievement has been verified on the 5G NR Mobile Device Test Platform ME7834NR. Background: Third Generation Partnership Project (3GPP) Release 16 defines many enhancements for 5G NR, addressing new industry verticals and network deployment scenarios by introducing support for capabilities such as Ultra Reliable Low Latency Communication (URLLC), Positioning for NR, Dual Active Protocol Stack (DAPS) and enhanced MIMO/ Handover. With the increase in the number of supported Radio technologies and associated frequency band combination, the size of the Radio Capability information has become significantly large and hence an efficient method for Optimized transfer of this Signalling information has been defined with RACS. The conformance tests are defined by 3GPP in TS 38.523-1 and have been submitted to 3GPP Radio Access Network Working Group 5(RAN WG5) by Anritsu. These tests will also be submitted to Global Certification Forum (GCF) Certification Agreement Group (CAG), and PCS Type Certification Review Board (PTCRB) PTCRB Validation Group (PVG) for approval in the upcoming meetings. ■ Anritsu Corporation www.anritsu.com World-First 5G Vehicle OTA RF Test System Anritsu Corporation is pleased to announce development of the world’s first 5G OTA RF test system in partnership with Toyota‘s and their investment in MVG OTA test environment using Anritsu´s Radio Communication Test Station MT8000A. Realizing autonomous driving requires simultaneous communications with the surrounding environment, including other vehicles, road infrastructure, networks, etc. In particular, introduction of 5G supporting large-capacity, low-latency, massive connections are key technology to transferring the large data volumes generated by various sensors, such as vehicle cameras, as well as for 3D high-definition mapping data. Consequently, car manufactures, and Telematics Unit suppliers are pushing forward with development of 5G communications products. The developed 5G communications products are installed in vehicles as the “connected car”. However, before release, the connected vehicle communications performance must be tested and verified in an OTA environment simulating the actual environment as possible. Now, Anritsu and Microwave Vision Group (MVG) have partnered to deliver the MT8000A and OTA system to Toyota as the world’s first 5G vehicle OTA RF test system. The all-in-one Radio Communication Test Station MT8000A is a 5G base-station simulator for 5G RF and protocol measurements as well as application tests. It supports high-order 4x4 MIMO and carrier aggregation (8CA) technologies for fast, large-capacity communications. As well as focusing on smartphone testing, it covers a wide application range, including 5G communications function tests and evaluations of antennas and high-frequency parts. To characterize an antenna, it is necessary to measure its radiation patterns to determine how well, and in which direction, it radiates. To quickly obtain reliable 3D radiation patterns, antenna performance tests are moving towards Over-The-Air (OTA) test solutions to obtain fast and reliable measurements at the system level. For OTA measurements, the tests are performed through a radio communication tester and are conducted using a near-field measurement method in an anechoic chamber to block external electromagnetic fields and to simulate realistic and complex RF scenarios. Addressing the complexity of measuring highly connected vehicles, MVG offers OTA measurement solutions specifically designed for the complete verification of automotive wireless performance. Thanks to a high precision positioning system (controller and turntable) continuous on-the-fly measurements can be performed. This allows for quick and accurate measurement of directivity, gain and efficiency. ■ Anritsu Corporation www.anritsu.com hf-praxis 2/2022 51
