近些年来，群集BBU（BaseBandUnit，基带单元）、拉远RRU（RadioRemoteUnit，射频拉远单元）的C-RAN（Centralized,Cooperative,Cloud&Clean-RadioAccessNetwork）收集枚举在寰球许多国度以及地域患上到了越来越普及的使用，但受CPRI（Co妹妹onPublicRadioInterface，通用人民无线电接口）的限度以及现有BBU/RRU接口带宽申请高的影响，若因循CPRI举行前传组网，则会限度C-RAN更大规模的枚举；
另外面向4.5G及未来5G的无线本领也对于现有CPRI提出了新的挑战。
本白皮书旨在处置这些下场，提出了NGFI（NextGenerationFronthaulInterface，下一代前传接口），并列出多种可选的接口成果松散方案。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
