Amarisoft公司由法国软件天才Fabrice Bellard（Qemu和ffmpeg的开发者，全世界排名前10的程序员，战斗力相当于100+人的团队！）及Franck SPINELLI于2012年成立，是一家致力于电信行业的软件公司。旗下的4G 5G作品可以不依赖专用硬件，直接在通用PC上运行的纯软件来替换大部分4G/5G组件。 目标用户群体：运营商、科研机构、通信工程专业学生&导师、通信安全研究员。 官网介绍
本文是通过Amarisoft + osmocom sim 卡 + USRP B200 mini 实现的LTE NBIoT NR的实验测试。
实验环境：
系统架构
SDR硬件+Ubuntu 18+带密钥的SIM卡（osmocom可编程SIM卡）+法拉第笼 or 信号屏蔽箱
UE：小米9 Pro 5G ( 4G LTE + 5G NSA ) & OnePlus 8 Pro ( 4G LTE + 5G SA、NSA )
SIM鉴权密钥:
虽然USRP硬件作为射频前端，功率比较小，有效只是几米范围内，但还是建议配合手机屏蔽箱：
