Bring V2X Development Testing from the Test Track to the Laboratory

For suitable development and communication test scenarios, a compact shielded OTA setup can reduce dependence on large RF test facilities and outdoor test environments.

By combining Morita Tech shield boxes with near-field antenna couplers, communication between V2X devices can be evaluated under controlled RF conditions while keeping the overall system compact.

Vehicle Connectivity Test Scenarios

V2X communication covers multiple connectivity scenarios between vehicles, infrastructure, pedestrians and networks.

V2V

Vehicle-to-Vehicle communication evaluation.

V2I

Vehicle-to-Infrastructure communication scenarios.

V2P

Vehicle-to-Pedestrian connectivity scenarios.

V2N

Vehicle-to-Network communication scenarios.

The test configuration shown on this page focuses primarily on a V2V bench-test scenario.

How It Works

Reproducing V2V Communication Conditions on the Bench

The V2X OTA system creates two shielded RF environments representing two vehicles and connects them through a controlled RF path.

5.9 GHz V2X Communication

The FA-600 antenna couplers are used to establish OTA communication between the two shielded test environments.

Variable RF Attenuation

RF attenuation can be adjusted to reproduce different path-loss conditions corresponding to changes in vehicle distance.

GNSS Signal Integration

GNSS signals can be introduced into the shielded test setup for integrated automotive connectivity evaluation.

Vehicle Orientation Simulation

Rotation and elevation stages allow antenna orientation and inclination to be varied under controlled conditions.

Real Test Environment

From Test Concept to a Real Shielded OTA Environment

The system combines dedicated shield boxes with antenna couplers and positioning stages to create a compact, reproducible V2X development test environment.

Shielded RF Environment

Two shield boxes provide isolated environments for the V2X devices under test, helping reduce external RF interference and improve test repeatability.

The shielded setup allows communication conditions to be evaluated in a controlled laboratory environment before moving to more complex outdoor or proving-ground tests.

By separating the transmitting and receiving V2X devices into dedicated shielded environments, engineers can create stable and repeatable RF conditions for development and comparative testing.

  • Reduced influence from external RF signals
  • Repeatable laboratory test conditions
  • Controlled V2V communication evaluation

FA-600 with Two-Axis Positioning

The FA-600 antenna coupler is installed inside the shield box together with a positioning mechanism that enables controlled changes in antenna orientation.

Rotation and elevation adjustment allow the test setup to reproduce different relative antenna angles and vehicle orientation conditions while keeping the RF environment controlled.

  • Rotation adjustment
  • Elevation / tilt adjustment
Distance Simulation

Simulate Vehicle Distance Without Physically Moving Vehicles

Instead of changing the physical distance between two vehicles, RF attenuation can be varied to reproduce different propagation-loss conditions in a controlled laboratory environment.

Rotation

Change the horizontal antenna orientation to reproduce different relative vehicle positions and communication angles.

Tilt

Adjust antenna inclination to evaluate how changes in vehicle or antenna angle can influence communication conditions.

GNSS Integration

GNSS signals can be introduced into the shielded test environment for integrated V2X and positioning-related connectivity evaluation.

Morita Tech Antenna Coupler

FA-600 Wideband Antenna Coupler

The FA-600 wideband antenna coupler covers 600 MHz to 6 GHz and includes the 5.9 GHz frequency range used for V2X communication evaluation.

Morita Tech antenna couplers are designed for close-proximity OTA testing. By coupling to the device under test at short distance, the test setup can reduce the influence of surrounding reflections and support reproducible wireless evaluation inside a compact shielded environment.

Combined with a suitable shield box, the FA-600 can be integrated into a compact automotive connectivity test setup for V2X development and R&D.

600 MHz – 6 GHz Wideband Coverage

One antenna coupler covers a broad frequency range including the 5.9 GHz V2X band.

5.9 GHz V2X Communication

Suitable for V2X communication evaluation at the 5.9 GHz frequency range used in the test system.

Near-Field OTA Close-Proximity Coupling

Enables OTA evaluation at short distance from the DUT in a compact test configuration.

High Repeatability Controlled RF Environment

Helps reduce the influence of surrounding reflections and supports reproducible measurements.
