Over-the-Air (OTA) Performance Testing

Ensuring Reliable Wireless Device Performance in Real-World Conditions​

DEKRA’s Over-the-Air (OTA) Performance Testing services help manufacturers validate the performance of wireless devices under realistic usage conditions. By simulating live network environments, OTA Testing verifies that devices deliver excellent user experience, provides seamless connectivity, and fulfills network operators and industry requirements.​

About OTA Performance Testing​

OTA Performance Testing evaluates how effectively wireless devices operate in real-world conditions. It measures the complete signal path, from transmission to reception, taking into account the performance of the device's antenna system in typical usage scenarios.​
OTA Testing services assess the RF performance of transmitters and receivers, including the effects of antennas, device housing, and the proximity of the human body or other objects. OTA Testing helps to understand how those factors impact device performance across various positions and orientations during use.

Comprehensive and reliable OTA Testing Services across a range of wireless technologies​

DEKRA laboratories are equipped with advanced facilities that conduct a wide range of OTA evaluations. ​Our facilities include fully anechoic chambers for SISO (Single Input Single Output) and MIMO (Multiple Input Multiple Output) testing, reverberation chambers, multi-channel emulators and human body models that simulate device usage near the head, wrist or hand.
With deep expertise in industry standards for OTA Testing, such as 3GPP, CTIA, PTCRB and GCF, we support manufacturers throughout the development lifecycle, from the R&D phase to product certification. Our customized testing plans are designed to suit each product's specific type, size, and market application. This approach helps our customers reduce development time, ensure compliance, and expedite access to global markets.
