Difference between CDMA and LTE

CDMA

CDMA, Code Division Multiple Access is a protocol used for 2G and 3G communication. In CDMA, a channel carries all types of transmission simultaneously without division of bandwidth or time. Data from different stations is transmitted simultaneously using different code modulation.

LTE

LTE is a high-performance interface for cellular mobile communications. It supports high-speed networks and at present, it is the fastest network protocol for smartphones and mobile phones.

The following are some of the important differences between CDMA and LTE.

Sr. No.	Key	CDMA	LTE
1	Concept	CDMA is a set of protocols used in 2G and 2G mobile communication networks.	LTE is a protocol used in 4G broadband technology and has high-speed data access.
2	Transmission Standard	CDMA uses Spread-Spectrum Multiple Access, SSMA for transmission.	LTE uses Orthogonal Frequency Division Multiplexing, OFDM for transmission.
3	SIM Cards	CDMA does not require a SIM Card(s) for authentication.	LTE requires SIM Card(s) for authentication.
4	Multi-path Signal	CDMA cannot handle the multi-path signal properly.	LTE can handle multi-path signals efficiently.
5	Standard	CDMA is a set of protocols for 2G/3G wireless communication.	LTE is now-a-day, a de-facto standard for 4G High-Speed wireless communication.
