空中(OTA)测试

im体育APP’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.

OTA testing measures the antenna radiated performance and signal path in a simulated environment to ensure devices perform as intended on the live network by end users. The OTA evaluation of 总辐射功率(TRP), 总各向同性灵敏度(TIS) and Intermediate Channel Sensitivity are key metrics to optimize performance prior to production and market release.

im体育APP provides OTA testing for your commercial, 工业, 军品, and consumer products such as smartphones, 笔记本电脑, 平板电脑, 路由器, 和物联网设备. Our state-of-the-art OTA test chambers in the US cover 400MHz to 7.125GHz as well as the 28GHz and 38 GHz mm-Wave frequencies.
