码分多址 (CDMA):
在 CDMA 中,一个信道同时承载所有传输。既没有带宽的划分,也没有时间的划分。例如,如果一个房间里有很多人同时说话,那么如果只有两个人说同一种语言,那么完美的数据接收也是可能的。类似地,来自不同站的数据可以以不同的代码语言同时传输。

长期进化:
LTE是为蜂窝移动通信系统开发高性能空中接口的项目名称。它用于推进系列移动电信系统。它是一种高速数据网络。它是适用于智能手机和移动设备的最快无线网络。

让我们看看LTE和CDMA之间的区别:

S.NO. LTE CDMA
1 It is the 4G wireless broadband technology for high-speed access. It is a set of protocols used in 2G and 3G wireless communications.
2 It uses Orthogonal Frequency Division Multiplexing (OFDM) for transmission. It uses a spread-spectrum multiple access technique for transmission
4 It requires a SIM card to authenticate the handset. It mobile handsets do not support SIM cards.
5 It has better multi-path signal handling capability. It is not good at multi-path signal handling.
6 It is a de-facto standard for high-speed wireless communication. It is a set of protocols used in 2G and 3G wireless communication.
