Verification Services
for In-Vehicle and Telematics

When integrating 4G/5G wireless communication modules into vehicle-mounted telematics systems, comprehensive validation is essential to address diverse factors such as communication protocols, country-specific band support, seamless operation during cross-border travel, and emergency call (eCall) compliance—ensuring robust, reliable performance in real-world global deployments.

At Japan Novel, we deliver one-stop excellence in wireless validation—from test environment design and custom test case development to full-scale execution. We empower your telematics rollout with unmatched speed, precision, and global compliance, turning technical challenges into market advantages.

In-Vehicle TCU Verification Track Record

We have verification experience with in-vehicle TCUs in over 20 countries worldwide, focusing on Europe, North America, and ASEAN.

Field Testing

• 2G/4G areas, 3G/4G areas, 4G out-of-coverage areas, national borders, 5G corridors
• Device log capture & analysis

Pre-Operational Check / Lab Replication

In collaboration with measurement instrument vendors, we also establish environments in Japan to reproduce defects found in the field.

• Verification against simulators
• Operational verification within Japan
• Map creation using area monitors
• Reproduction environment setup using simulators

Example Test Items

Verifying Function Activation Triggers

Verifying Operation Differences Based on Communication Status

• Immediate failure of emergency call when out of coverage
• Communication maintenance during cross-border roaming

Emergency Call Support
(Compliance with European NG-eCall, North American eCall, Japanese Emergency Calls, and other country-specific standards)

In Europe, eCall (automated emergency calling) has been mandatory for all new type-approved passenger cars since April 2018, and NG-eCall will become mandatory from January 2026.

In the event of an accident, the in-vehicle communication unit automatically contacts the Public Safety Answering Point (PSAP) with Minimum Set of Data (MSD), including airbag/collision sensor information and the accident location (GPS coordinates).

Emergency Call Support (NG-eCall / eCall)

NTN Communication Verification
(Non-Terrestrial Networks: Satellite Communication, HAPS)

Verification Support using Simulators, Including Doppler Shift Correction

In NTN, communication with satellites and HAPS faces challenges such as long-distance transmission latency, Doppler shift, and radio signal attenuation along the communication path. We accurately reproduce these issues in a lab environment to verify the performance of devices and equipment.

Example Schedule

We provide one-stop support following the process below:

Preliminary Investigation
(2 Months)

Covers environment survey, confirmation of test equipment, and determination of major test categories.

In the preliminary investigation phase, we clarify "what can be done" and "what cannot be done" based on information such as terminal specifications, the customer's test environment (type of simulator, presence of a shielded room, etc.), and target sensors.

Test Preparation
(1–2 Months)

Includes test environment setup.

In the test preparation phase, we not only create the test specification document but also develop test scenarios for use with the simulator.

Test Execution
(1–2 Months)

Includes retesting upon defect occurrence.

In the test execution phase, if a defect occurs, we provide a detailed report from the perspectives of terminal specifications and 3GPP standards.
