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.
