The rapid expansion of wireless devices has generated an increased need for innovative and effective methods for testing. Conventional methods of testing with physical connection to the device have limitations and cannot guarantee the performance and reliability of a wireless device because real-world implications are not truly accounted for. This is where Over-the-Air (OTA) testing steps in—this innovative and transformative method assesses the performance of the wireless device in a controlled environment that represents real-world conditions. In this article, we will discuss OTA testing along with information on its importance and the advantages of OTA testing along with how it is influencing the future of wireless device certification, focusing on MU-MIMO technology.
What is OTA Testing?
OTA Testing is defined as measuring the wireless device performance in a facilitating condition, without a physical connection. This approach allows manufacturers to assess the wireless device performance in a multitude of controlled conditions that represent real world conditions. OTA testing typically entails placing the device into an anechoic chamber or reverberation chamber and performance is measured with specialized equipment.
Advantages of OTA Testing
OTA testing has many advantages compared to traditional testing methods. A few key benefits of OTA testing are listed below:
More Accurate Performance Evaluation
OTA testing provides a more accurate view of device performance in real-world conditions, including the impact of antenna design, propagation, and interference.
Less Test Duration or Time
OTA testing can save considerable test time because OTA testing does not require a physical connection to the device to be tested, and most measurements can be taken in less time than passive conducted testing.
Greater Reliability
OTA testing provides a more realistic testing environment for devices by testing in a more realistic environment, and there are substantially fewer errors and inconsistencies associated with OTA testing as opposed to some traditional testing methods.
How Does MU-MIMO Relate to OTA Testing?
MU-MIMO (Multi-User Multiple Input Multiple Output) is an advanced wireless communication technology. It helps a single base station to transmit data to multiple devices at the same time. The MU-MIMO technology depends on a very high-performance antenna design and beamforming capabilities that can only be measured by OTA testing.
During OTA testing, MIMO—devices are assessed based on their capability to serve many users at the same time. It also checks if MU-MIMO devices reduce interference and minimize throughput. Specialized test equipment and methods, such as multi-probe anechoic chambers and channel emulators are necessary. OTA testing helps manufacturers to validate their MU-MIMO devices’ performance against the required standards and provide end-users a seamless wireless experience.
Benefits of OTA Testing on MU-MIMO Devices
OTA testing offers a wide range of benefits for MU-MIMO devices which include:
Beacon and Beamforming Performance
OTA testing helps manufacturers to assess how well MU-MIMO beamform devices perform. It also ensures that they direct signals towards multiple users.
Interference Mitigation Assessment
OTA testing gives the manufacturers an opportunity to leverage the full-power driving capabilities of advanced MU- MIMO wireless technology. This determines the interference mitigation performance of MU-MIMO devices that would make connectivity reliable in an uncertain wireless environment.
Antenna Design Tuning
OTA testing enables the manufacturers to tune the antenna design of MU-MIMO devices, so they work at the most optimal level.
What’s Next in Wireless Device Certification?
In accordance with the new developments in technology, ensuring the operational capability of a device using OTA testing is increasingly becoming a necessity. It is mandatory for all manufacturers to guarantee high quality standards for their wireless devices compatible with the 5G and IoT infrastructure due to growing concerns over device economy and dependability. In this context, OTA testing enhances efficiency and reliability thereby proving to be both cost effective for manufacturers and certification bodies.

Role of OTA Testing in Future Wireless Technologies
Looking into the future, it is certain that OTA testing will have a crucial role in developing and certifying wireless devices. The expansion of 5G, IoT and other wireless technologies/applications will require manufacturers, suppliers and end user equipment to meet demanding performance and reliability requirements. OTA testing is a consistent and rapid means of assessing device performance, making it an essential service for manufacturers and certification organizations.
Over the coming period, further advancements in OTA testing methods and equipment will enable manufacturers to determine device performance measurements in a more constrained and realistic environments to ensure that wireless devices meet performance expectations. OTA Testing will continue to have an important role in wireless device certification, enabling manufacturers to deliver reliable devices to the consumers.
