Reliable Over-the-Air (OTA) Test Systems for Wireless Devices
TELECOM TEST TOOLS delivers high-performance OTA test solutions to measure, validate, and optimize RF characteristics in real-world simulation labs.
Over-the-Air (OTA) Test Systems
Over-the-Air (OTA) Test Systems are essential for evaluating the real-world performance of wireless devices without direct cable connections. These systems measure radiated RF performance, including antenna efficiency, total radiated power (TRP), and total isotropic sensitivity (TIS), in shielded or anechoic chambers. OTA testing is vital for ensuring wireless functionality, interoperability, and certification readiness in cellular, Wi-Fi, Bluetooth, and IoT devices.
TELECOM TEST TOOLS designs OTA test solutions for a wide range of device categories, from smartphones and wearables to automotive and industrial IoT products. Our systems replicate wireless operating conditions with precision and repeatability, enabling detailed analysis of signal propagation, antenna behavior, and user orientation impact. Located in Canoga Park, CA, TELECOM TEST TOOLS supports B2B clients across North America with reliable IoT test systems, expert support, and continuous innovation that help streamline development and ensure certification success.
