目前,随着手机和智能化移动终端的实现,先后推出了模拟网、GSM接入网技术、CDMA接入技术、GPRS以及3G通信接入技术,对于这些接入网技术,你熟悉多少呢? 1、模拟网 横拟网是我国早期建设的手机通信网。由于各地分别建设、时间先后不同,又有爱立信和摩托罗拉两大手机通信系统等原因,模拟移动电话网形成了A网和B网系统。A网地区使用A网的手机,B网地区使用B网的手机。模拟入网的信号以模拟方式进行
At present, with the realization of mobile phones and intelligent mobile terminals, analog networks, GSM access networks, CDMA access technologies, GPRS and 3G communication access technologies have been introduced. How familiar are you to these access network technologies? 1, simulation network Heng network is the early construction of China’s mobile communications network. Due to the different construction and time in different places, Ericsson and Motorola have two major mobile phone communication systems and other reasons, the simulation of mobile phone network formed A network and B network system. A network area using the A network of mobile phones, B network area B network using mobile phones. Analog network access signal to simulate the way
