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 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.
|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.|
