1.全球移动系统(GSM) :
GSM是用于移动电话通信的蜂窝标准,可以满足使用数字调制的语音服务和数据传输,而SMS对社会产生了深远的影响。它是2G技术的标准承担者。 GSM是电路交换网络。在GSM中,计费基于连接的持续时间。它不允许直接连接到Internet。 SMS(短消息服务)是受欢迎的功能之一。它几乎在所有国家/地区使用,并为大量用户提供服务。
2.通用分组无线业务(GPRS) :
GPRS是对GSM功能的升级,是对基本功能的升级,与标准GSM相比,GPRS可获得更高的数据速度和对分组数据网络的简单无线访问。它是2.5G技术的标准承担者。 GPRS是一个分组交换网络。在GPRS中,计费基于传输的数据量。它允许直接连接到互联网。 MMS(多媒体消息服务)是受欢迎的功能之一。不能将其提供给所有国家/地区,因为它仅限于具有适当网络连接的发达地区。
