说明: 移动电话主要采用频率复用,但分配给移动电话的频段很少,远不能满足用户的需要。
因此就提出将地区划分成小区,称为蜂窝(Cell),每个蜂窝内使用一组频率,相隔一段距离后,相同的频率又可重复使用。
(The main use of mobile phone frequency reuse, but allocated to the small-band mobile phone, far from being able to meet the needs of users. Therefore proposed to be divided into residential areas, known as cellular (Cell), each use a set of cellular frequencies, separated by some distance, the same frequency can be reused.)

之前计划写的沙盘系统,刚写好文件部分,也不算太完善,碰巧有人问起,遂贴上代码大家看去,你可以在此基础上完善之。 代码没什么WS技术,但做文件沙盘还是有不少问题的,需要的朋友可以下(Written before the planned sand table system, just part of the written document, but also not too perfect, someone happened to ask, accordingly paste the code we looked, you can improve on this basis, the. Code no WS technology, but do still have many issues paper sand table, and we need friends can, under)
