im体育APP’s Over-the-Air (OTA) testing services ensure your wireless products comply with operator/carrier requirements 和 international st和ards, allowing the performance of your wireless devices to be verified before your product hits the market.
什么是OTA测试?
OTA测试测量无线设备的可靠性, their antennas 和 components perform using simulated environments to replicate the live network experienced by end users. 测试测量总辐射功率(TRP)等参数, 总各向同性灵敏度(TIS), 和 Intermediate Channel Sensitivity to ensure optimal performance before market release. 通过模拟实时网络环境, OTA testing verifies that devices transmit 和 receive signals effectively, 确保产品质量, 网络的兼容性, 以及用户体验.
