Analysis by Testing Method

On the basis of the testing method, the market is subdivided into full vehicle OTA testing and standard multi-probe OTA testing.

The full-vehicle OTA testing segment is dominating the market. This approach assesses the performance and reliability of vehicle wireless technology by simulating real-world conditions within the vehicle. A complete vehicle is placed in a test chamber to evaluate its wireless components' performance. The method utilizes a single probe to analyze the antenna's efficiency in the vehicle's environment while taking into account the influence of the vehicle's structure and other electronic devices. This testing approach depends on advanced and intelligent sensing technologies such as Radar and Lidar. Additionally, it features high-performance ground and non-cellular services, along with a satellite link for navigation and network connectivity. Full vehicle OTA testing provides benefits such as reduced costs, quicker time to market, and the capability to adapt to technological advancements by facilitating continuous software updates. Hence, the demand for full vehicle testing is rising among automakers and vehicle owners.

The standard multi-probe OTA testing segment is witnessing substantial growth in the industry. This approach is essential for assessing the performance and reliability of wireless devices used in vehicles. Typically, this system is applied to Multiple Input Multiple Output (MIMO) systems. It employs a setup with multiple probes to test MIMO systems, often found in modern wireless technologies such as 5G. These systems are particularly effective at measuring the performance of MIMO setups, which utilize several antennas to improve data transmission and reception. Additionally, multi-probe configurations can replicate complex, realistic wireless environments, incorporating multipath effects and interference.

• For instance, in March 2025, Keysight Technologies, Inc., combined with Mavenir to test and validate Mavenir’s 32TRX massive multiple input multiple output (MIMO) technologies using Keysight’s comprehensive Beam MIMO Detect solution for efficient beamforming with massive antenna element next-generation Node B (gNBs). This collaboration helps ensure the robustness of Mavenir’s solution, delivering an optimal user experience through a comprehensive and efficient testing process.

Analysis by Testing System

On the basis of the testing system, the market is subdivided into full vehicle OTA testing and standard multi-probe OTA testing.

The near-field testing system has become the leading solution for Automotive Over-the-Air (OTA) testing systems. This system uses a probe to evaluate the radiation patterns of antennas, especially those installed on vehicles, from a close distance. Near-field testing allows for more compact and efficient testing setups by assessing the antenna's performance in close proximity, which is beneficial for various applications. Given the small size and diverse locations of antennas on vehicles, a spherical type of near-field measurement is essential for a comprehensive evaluation. During the near-field testing setup, the vehicle is placed on a turntable or inside a specialized anechoic chamber to facilitate the assessment of the antennas. In addition, this system allows testing to be conducted indoors, which eliminates the issue related to electromagnetic interference. Smaller space requirements make it more practical for automotive applications.

Compact range testing system enables the far-field measurement of vehicle antennas in a more limited enclosed space by utilizing a reflector to convert a spherical wave into a plane wave, allowing for precise testing at reduced distances. The demand for this system is increasing due to advantages such as requiring less space, which is beneficial for larger vehicles, as well as higher efficiency and accuracy. The time and costs involved in antenna testing are significantly lower. Thus, the adoption of compact range testing systems is on the rise.
