作为高技术通信三大传输方式之一的扩频通信因具有一般窄带通信难以替代的优良性能，而逐渐为各种通信网所应用，但至今在国内民用领域尚处于起步阶段。为此，介绍该通信方式的特点，并以石家庄电业局的应用情况为例，说明扩频通信在电力部门中，特别是小区域或县级电网中是具有发展前途的通信方式
As one of the three transmission modes of high-tech communication, spread spectrum communication is gradually applied to various communication networks due to its excellent performance of being difficult to be replaced by general narrow-band communication. However, up to now, it is still in its infancy in the civil field in China. To this end, the characteristics of this communication method are introduced and the application of Shijiazhuang Electric Power Bureau is taken as an example to show that spread spectrum communication is a promising communication method in power sector, especially in small area or county power grid
