ÌìÃÀ´«Ã½’s Over-the-Air (OTA) testing services ensure your wireless products comply with operator/carrier requirements and international standards, allowing the performance of your wireless devices to be verified before your product hits the market.

 

What is OTA testing?

OTA testing measures how reliably wireless devices, their antennas and components perform using simulated environments to replicate the live network experienced by end users. Testing measures parameters like Total Radiated Power (TRP), Total Isotropic Sensitivity (TIS), and Intermediate Channel Sensitivity to ensure optimal performance before market release. By simulating live network environments, OTA testing verifies that devices transmit and receive signals effectively, ensuring product quality, network compatibility, and user experience.
