日本运营商禁用华为设备？日本媒体给中国人开了一个不实现的玩笑
最近这几年，美国一直宣扬中国的通讯设备会威胁国家的通讯安全，刚开始的时候只有美国本土禁用华为与中兴的通讯设备，可是在美国不间断的宣扬下，不少美国的盟友也加入了这个行列！今天日本经济新闻发表了一篇文章，在文章中表示日本三大运营商之一的软银集团计划禁止使用华为的4G网络设备，华为留下的空缺由诺基亚与爱立信填补！虽然此消息并未得到证实，可是了解其中详情的人都知道这是不可能的，这是日本媒体给中国人开的一个玩笑而已。为什么说日本经济新闻这则报道是一个不可能实现的玩笑呢？软银集团是唯一使用华为与中兴通讯设备的日本运营商，软银集团使用华为与中兴通讯设备的原因除了跟中国关系好以外，华为与中兴的通讯设备的技术适用于软银集团手中所拥有的频谱是有关系的。
早在4G商用的时候，软银集团就使用华为与中兴的设备组建了TD-LTE的网络，TD-LTE网络所覆盖的区域虽然没FDD-LTE广阔，速度也没FDD-LTE，但是由于TD-LTE占用频段少，节省资源，带宽长，适合区域热点覆盖，两种技术互相弥补是最合适的建网方案。软银集团不使诺基亚与爱立信建TD-LTE网络的原因是因为大部分TD-LTE标准都掌握在中国通讯企业手中，即使诺基亚与爱立信有这种设备出售，价格也会十分昂贵。
构建一张通讯网络除了基站与建设费用昂贵以外，最昂贵的那就是频谱资源，由于频谱资源是有限存在的，不可能凭空增加，如果全部网络都使用FDD-LTE的标准建网，那么网络资源肯定不够的，分给运营商的频率也就更少了，未来还要增加一个5G网络，频谱资源就会更稀缺！华为与中兴掌握TD-LTE这项技术正是通讯市场不可或缺的重要因素。软银使用TD-LTE网络已经这么多年，突然间要他移除这张赚钱的网络，怎么可能实现呢？
