OTA testing services for wireless products support development, RF performance, FCC/ISED, CE for RED, CTIA for PTCRB or GCF and carrier approvals for networks.
Over-the-air (OTA or RF OTA) testing evaluates the real-world radio frequency (RF) performance of wireless devices in radiated conditions. Unlike conducted RF measurements, OTA testing assesses the complete product, including the integrated antenna and enclosure, as it will be used in the field.
TÜV SÜD provides OTA testing services to support product development, performance verification, regulatory, and Mobile Network Operator (MNO/Carrier) approval for the United States, Canada, and the EU, including FCC/ISED, CE for RED, and CTIA requirements, as well as Global Market Access for connected devices.
Modern wireless products increasingly rely on compact form factors, embedded antennas, and multiple radio technologies. As a result, RF performance can be significantly influenced by enclosure materials, internal layout, and the interaction between radios.
OTA testing is used to:
OTA testing is commonly required for cellular and IoT devices and is increasingly used as part of both pre-certification and certification test strategies in North America.
TÜV SÜD conducts OTA testing using specialized test setups designed to provide accurate and repeatable radiated measurements.
Key parameters include:
Testing can be performed across multiple frequency bands and wireless standards based on product and regulatory requirements.
OTA testing is typically required when:
TÜV SÜD’s OTA testing services support a wide range of wireless technologies used across modern connected devices.
As products increasingly combine multiple radios and operate across different frequency bands, testing must reflect real-world usage conditions.
Both single-radio and multi-radio devices can be evaluated, including configurations such as multi-SIM or multi-band devices, where interactions between radios may impact performance.
OTA testing may be applied at multiple stages of the product lifecycle, including:
Pre-compliance OTA testing helps manufacturers identify potential issues early and reduces the likelihood of retesting during formal certification.
OTA testing is commonly applied to products where radiated RF performance is critical, including:
Test programs are defined based on product design, intended use, and regulatory scope.
OTA testing follows a structured process designed to support certification and approval requirements while maintaining efficiency.
OTA testing is conducted using specialized chambers and measurement systems designed to accurately capture device performance across multiple frequency bands.
We use our OTA chambers and measurement platforms to carry out SISO and MIMO cellular testing in line with CTIA Mobile Station OTA test plans. The same setups also support Wi-Fi RF performance evaluation for mobile converged devices, helping manufacturers to comply with industry standards.
OTA testing evaluates the RF performance of wireless devices and is required for certification, compliance, and carrier approval.
Yes, OTA testing is often required to demonstrate compliance with regulatory standards.
OTA testing is typically conducted on final or near-final hardware before certification.
A failed test indicates the device does not meet required performance thresholds and may need design adjustments before re-testing.
Timelines vary depending on device complexity and scope.
Device specs, target markets, and certification requirements.
OTA testing requirements vary depending on your product design and target markets.
TÜV SÜD works with manufacturers to define the right testing strategy for certification and approval.
