GSM和LTE的区别

1. 全球移动通信系统(GSM)：
它是全球手机用户广泛使用的移动网络。在这种情况下，客户的信息被放在一张可以携带在新手机中的 SIM 卡上。它在 900 MHz 或 1, 800 MHz 频带上运行。在GSM中，使用了两种技术：FDMA和TDMA。

2.长期演进(LTE)：
它是高速数据通信的标准。它提供大约 100 Mbps 的下载速度和大约 50 Mbps 的上传速度。它在使用数据服务时不能提供良好的语音通话质量。它需要一张 SIM 卡来验证手机。

GSM和LTE的区别：

S.NO	GSM	LTE
1.	GSM supports both voice calls and data.	Whereas it is used only for high speed data communication.
2.	GSM uses Frequency Division Multiple Access(FDMA) and Time-division multiple access(TDMA).	Whereas it uses Orthogonal frequency division multiple access(OFDMA) and Single-carrier frequency division multiple access(SC-FDMA)
3.	In CSM, information is transported through channels that are separated into physical and logical channels.	Whereas in LTE, information is carried using physical, logical and transport channels.
4.	In GSM, two frequency bands are used 900 MHz and 1800 MHz.	Whereas in LTE, frequency bands from 1 to 25 and from 33 to 41 are reserved for FDD( Frequency Division Duplex) and TDD(Time Division Duplex) respectively.
5.	In this, the information of customer is stored in sim card.	Whereas in this, a sim card is required to verify the mobile phone.
6.	It is comparatively slow network.	Whereas it is the fastest network.
