DFS Testing

We KMO have an advanced speech laboratory, which can provide tests for speech performance and sound safety requirements, and specialize in testing for electroacoustic measurement of hearing aids. The advanced test laboratory includes an anechoic chamber, equipped with professional measurement analyzers, various test head couplers or ‘HATS’ (head and torso simulators) that meet the requirements of acoustic testing, and professional microphones and audio sources. Further testing can be performed on demand. If you have special requirements, please feel free to contact our KMO acoustic experts.

We KMO have a communication lightning strike laboratory, which can provide lightning strike safety tests for communication ports. Equipped with international advanced multifunctional communication wave generators and various coupling and decoupling networks, it can perform international telecommunication ITU-T regulations and tests. Further testing can be performed on demand. If you have special requirements, please feel free to contact our KMO.

In response to the continuous development of global wireless communication technology and the continuous emergence of various new technology man-machine interfaces, KMO Laboratories utilizes a global partner network to provide consulting and agency application services for various patent logos to meet the changing needs of customers Kind of certification requirements.

动态频率选择DFS是一项功能，可以监视频谱并为尚未使用的操作选择频率，以避免对诸如天气或军用雷达之类的无线电传输造成干扰。这是国际电信联盟（ITU）对在5GHz UNII频段中运行的设备施加的功能，在该频段中，雷达系统具有频谱保护功能。如果设备检测到存在雷达，则它必须选择备用信道，或者如果没有可用信道，则必须进入“睡眠模式”。

我们KMO实验室的DFS测试系统支持波形回放模式，允许为DFS研发或性能测试创建符合标准或自定义的波形文件。它可以支持具有所有兼容雷达波形类型的全球DFS标准，包括FCC，ETSI，日本MIC，韩国和中国DFS标准。

我们领先的测试设备支持全球DFS标准，同时经验丰富的人员亦获得权威机构的测试认可。标准化或定制的波形在执行DFS研发或运行性能测试时提供了灵活性。针对DFS频段以及在DFS频段中运行的产品通常涉及的其他频段的一站式无线服务得到了充分体现。


我们提供具有成本效益的解决方案，灵活的计划，出色的交付周期并提供测试解决方案。所有测试和报告均以合理/及时的方式进行，并牢记您的特定要求。

我们KMO的排队预约时间最快只有3天，而且我们KMO提供即时Online Order的高效增值服务。通过将DFS测试与其它测试和认证需求（电信入网，移动入网，无线射频，电磁兼容，安全性，环境，能源效率，性能等等）捆绑在一起，可以节省时间和金钱。借助KMO，您将消除使用多个实验室的麻烦，物流延迟和运输成本。
