摘　　要：随着5G物联网(Internet of Things,IoT)的快速发展,针对下一代IoT通信的特点,6G-IoT网络将会进一步优化海量机器通信(massive Machine Type Communication,mMTC)场景,从而促进新一代无线设备如超大规模多输入多输出(Extremely Large-scale Multiple-Input Multiple-Output,XL-MIMO)设备等的快速发展。针对此类设备尺寸大、无内置测试接头的特点,重点分析了多种空中下载(Over-The-Air,OTA)技术用于此类设备测试的优缺点,提出了一种适用于6G-IoT设备的电搅拌混响OTA测试方案,并通过对比多台5G-IoT终端的在OTA暗室以及OTA混响室的测试结果,初步验证了所提方案的可行性。With the rapid development of 5G-Internet of Things(IoT)applications,6G-IoT networks will further optimize massive Machine Type Communication(mMTC)scenarios for next-generation IoT communications,thereby promoting the rapid development of next-generation wireless devices such as Extremely Large-scale Multiple-Input Multiple-Output(XL-MIMO)devices.In view of the large size and no built-in test connector of such devices,this paper analyzes advantages and disadvantages of OTA testing technology for such devices,and proposes a reverberation chamber Over-The-Air(OTA)test with source stirring scheme suitable for 6G-IoT devices,and preliminarily verifies the feasibility of the proposed scheme by comparing the OTA test results of multiple 5G-IoT terminals in both anechoic chamber and reverberation chamber.
