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

5G Connectivity

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.

Solutions:

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.

Solutions:

eCall/ERA-GLONASS

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.

Solutions:

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.

Solutions:

Cybersecurity Solutions

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.
