Growth Factors in the Over-the-Air (OTA) Testing Market

• Global 5G Deployment and Network Complexity

The rapid, large-scale deployment of 5G New Radio (NR) networks worldwide is a primary catalyst for the Over-the-Air (OTA) testing industry's expansion. 5G technology introduces complex features like millimeter-wave (mmWave) spectrum usage, massive Multiple-Input Multiple-Output (MIMO) antenna arrays, and beamforming techniques. These elements significantly challenge the traditional testing methods, making comprehensive OTA validation indispensable. The cellular networks technology segment, which includes 5G testing, accounted for over 37.0% of the market's revenue share in the most recently reported year, demonstrating its dominance. Furthermore, the mandatory conformance and certification protocols for 5G devices, often driven by global bodies and regional telecom authorities, ensure a sustained high demand for sophisticated OTA chambers and services.

• Proliferation of Connected Devices in the IoT Ecosystem

The massive and continuous expansion of the Internet of Things (IoT) ecosystem, encompassing everything from consumer wearables to industrial sensors, is a critical growth factor. Each connected device, which may range from smartwatches to industrial gateway devices, requires reliable wireless performance to function seamlessly within its network and environment. Over 65% of electronic devices currently feature built-in wireless capabilities, underscoring the vast testing pool. This proliferation forces manufacturers to adopt rigorous OTA testing to ensure antenna efficiency, signal integrity, and energy-efficient communication, especially for battery-powered IoT gadgets. The need to certify low-power wide-area network (LPWAN) devices and general IoT modules, which often operate on different standards, drives the demand for multi-protocol, scalable OTA solutions.

• Automotive Shift to Connected and Autonomous Systems

The fundamental transformation of the automotive industry towards connected and autonomous vehicles is fueling a substantial need for OTA testing solutions. Modern vehicles now function as sophisticated wireless hubs, relying on Vehicle-to-Everything (V2X) communication, advanced driver-assistance systems (ADAS), and constant software updates delivered over-the-air. The automotive segment is one of the fastest-growing application areas, expected to command a significant market share by the next decade. Companies like Rohde & Schwarz are actively developing sophisticated Vehicle-in-the-Loop (VIL) systems for OTA testing, which can realistically simulate complex driving and propagation scenarios to validate the safety and reliability of these mission-critical communication systems before deployment.

Key Trends in the Over-the-Air (OTA) Testing Market

• Integration of Artificial Intelligence (AI) and Machine Learning (ML)

A major trend is the integration of AI and ML into OTA testing workflows to enhance efficiency and decision-making. Testing companies are developing platforms that use AI to optimize test plan generation, reduce the time spent on manual configuration, and automatically identify performance anomalies that human operators might miss. For instance, some advanced testing software utilizes ML algorithms to analyze vast datasets of measured antenna patterns and signal conditions, allowing them to predict potential device failures in complex real-world environments. This shift towards "smarter" testing is crucial for managing the sheer volume and complexity of multi-antenna, multi-band devices, enabling faster time-to-market for manufacturers.

• Expansion of mmWave Testing Capabilities

The move into millimeter-wave (mmWave) frequencies (typically above 24 GHz) for 5G and emerging high-speed applications is driving the demand for specialized OTA testing equipment and methodologies. Due to the extremely short wavelengths of mmWave signals, even slight misalignment or environmental factors can dramatically impact performance, making traditional conducted testing unfeasible. The proliferation of devices with massive-MIMO antennas, which can contain up to 128 radiating elements, necessitates complex near-field-to-far-field (NF-FF) transformation algorithms. Keysight Technologies, for example, offers advanced compact antenna test ranges (CATRs) designed specifically to accurately and repeatably characterize the performance of these high-frequency, complex antenna systems in a controlled chamber environment.

• Focus on Non-Terrestrial Network (NTN) and Satellite Communication

An emerging and significant trend is the increasing need for OTA testing solutions tailored for Non-Terrestrial Networks (NTN), which include Low Earth Orbit (LEO) satellite communications. As global initiatives push for ubiquitous connectivity, integrating satellite-based communication into standard consumer and industrial devices is becoming more common. This requires testing solutions that can simulate the unique orbital mechanics, Doppler shifts, and extreme propagation delay conditions inherent to satellite links. In response, partnerships are forming, such as one between ETS-Lindgren and Keysight Technologies, to launch the first OTA testing solutions specifically designed for Narrowband NTNs. This ensures that devices for remote, maritime, and aerospace applications can maintain reliable performance outside the reach of traditional cellular infrastructure.
