Test Automotive Wireless Technologies from R&D to Production
According to Counterpoint Technology Market Research Ltd., the number of connected cars with built-in connectivity expected to ship between 2018 and 2022 will reach 125 million units. Connected technology brings new functions and performance to vehicles and forms a key base for delivering new services and business. For example, connected technology has a major impact on remote monitoring of vehicle status as well as on function updates using wireless communications (OTA updates) to provide new services. Additionally, roll-out of commercial 5G services will drastically strengthen connectivity.
On the other hand, incorporation of various wireless communications technologies, including 5G, increases the complexity of the communications environment as well as the likelihood of radio interference. Increasing the number of network-connected onboard systems also greatly increases the risk of hacking threats to safety. Automobile manufacturers are facing new cybersecurity problems, making support for both rapid threat response and specialist communications technologies more important than ever before.
As a leading supplier of 5G measurement solutions, Anritsu has a wide range of measurement solutions for OEM businesses and suppliers requiring onboard wireless measurements. Anritsu solutions for every stage from R&D to manufacturing meet the latest industry test standards to help raise test efficiency and accelerate time-to-market.
Wireless Connectivity Solutions
Development of advanced connected cars and self- driving vehicles requires a 5G network environment. Effective tests are required to confirm whether or not the connected car and self-driving vehicle RF/Protocol/Application layers are in compliance with the latest 3GPP standards.
Telematics Evaluation Solutions
Telematics system development engineers are experiencing increasing daily workloads in development and evaluation work due to the continuing evolution of wireless communications technologies.
Anritsu labor-saving solutions increase the efficiency of telematics system development and evaluation.
eCall is an EU automobile emergency response information system installed in all new vehicles sold within the EU since March 31 2018. Since it is a system designed to protect human life, assuring the performance of the overall eCall system is extremely important. IVS developers must test whether the IVS performance and functions satisfy the compliance requirements for 2G/3G/LTE network environments.
Russia is also introducing its own ERA-GLONASS emergency response system which is similar to eCall.
eSIM OTA Solutions
The automobile market is focusing on an eSIM that does not require changing the SIM card. Since eSIM provision requires advanced technology, each country has defined national test requirements.
Although network connections increase the usefulness of the connected car, they also increase cyber security threats, in turn increasing the need for automobile security penetration testing.
Vehicle Acoustics Evaluation Solution for Wireless Communications Environment
The number of automobiles with built-in communications functions is increasing and communications, such as hands-free operation requiring the same voice quality as smartphone usage, is becoming commonplace. However, connections between peripheral equipment and IVS are becoming more complex, causing problems with communications latency and making evaluation of voice quality extremely important.
Combining Anritsu’s Signalling Tester MD8475A/B with the ACQUA from HEAD acoustics GmbH, a leading company in audio evaluation, provides the perfect audio evaluation solution for configuring replay tests in the actual acoustics environment.
Evaluation of RF Characteristics using Optimized OTA Measurement
Assuring WLAN quality is becoming more important as automobile cabin WLAN devices become common and data traffic volumes increase to provide infotainment while driving, map data updates, etc.
As part of its quality inspection regime, the automobile industry is favoring evaluation of WLAN device RF characteristics in an Over The Air (OTA) environment closely mimicking actual usage.
With its wide dynamic-range performance, the Wireless Connectivity Test Set MT8862A not only supports evaluation of RF characteristics while the WLAN is connected, but is also the best solution for OTA tests where signals can be unstable.
Testing Automobile Cabin WLAN Characteristics
Evaluating the performance of standalone WLAN modules is inadequate for implementing stable communications using cabin WLAN products. As required by IEEE802.11b/g/a/n/ac (2.4 GHz, 5 GHz), the Wireless Connectivity Test Set MT8862A supports quantitative evaluation of TRx characteristics while the WLAN product is communicating in the actual usage environment.
Bluetooth SIG RF Verification Test
Automobile cabin infotainment systems use Bluetooth technology for operations such as playing music and hands-free communications, especially via smartphone. This technology is standardized by the Bluetooth Special Interest Group (Bluetooth SIG) which also specifies the required test cases. The Bluetooth Test Set MT8852B supports all the Bluetooth SIG-certified RF tests and has a wide application range from R&D to production-line testing.
- Supports Basic Rate/Enhanced Data Rate RF tests used by hands-free communications and infotainment systems
- Supports Bluetooth Low Energy RF tests used by keyless entry systems, etc.
- Supports tests of Adaptive Frequency Hopping (AFH) function for restricting impact of interference signals, such as WLAN, on Bluetooth channels
Dynamic Maps Communications Evaluation Environment
Cellular and Wi-Fi networks are the typical communications methods for streaming dynamic maps. Since the MD8475B not only simulates a cellular network, it also can simulate various faults and changes in the communications conditions that may occur when updating dynamic maps by using with a Wi-Fi access point.
Radio Communications Test Station MT8000A
The MT8000A is an all-in-one 5G base station simulator supporting both sub-6 GHz band and mmWave-band RF tests and protocol tests. Combined use with the OTA Chamber supports 3GPP-defined mmWave RF call-connection tests and beam-forming tests. It can also be used for testing existing LTE environments; a 5G-to-LTE NSA (Non-Standalone) test environment can be configured easily and supports a self-driving vehicle development environment.
Signal Analyzer (Base Station Simulator) MD8475B
The MD8475B is an all-in-one base station simulator supporting LTE-A/LTE, etc., test environments. The easy-to-use SmartStudio GUI-based software is used to create test sequences for controlling self-driving vehicles using a GUI, cutting the time required for test environment settings. Using these functions simplifies tests of telematics control unit (TCU) and data communications modules to speed- up implementation. Supports eCall/ERA-GLONASS/ NG-eCall tests.
Radio Communications Analyzer MT8821C
The MT8821C is an all-in-one radio communications analyzer covering the 2G/3G/LTE/LT-A cellular communications methods used by telematics systems.
