What’s CDMA?CDMA (Code-Division Multiple Access) CDMA is a form of multiplexing, which allows numerous

signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency (UHF)  systems in the 800-MHZ and 1.9-GHz bands. 

Researchers started even 1950.IS-95 The narrow band CDMA mobile network has been

standardized in 1993.CDMA wideband CDMA system Such as CDMA2000 in US

and Europe and WCDMA developed in 1990 and still ongoing

Long Term Evolution (LTE) 4G technology refer to or short name of fourth Generation which was started from late 2000s. Capable of providing 100Mbps – 1Gbps speed. One of the basic term used to describe 4G is :.

Mobile MultimediaAnytime AnywhereGlobal Mobility SupportIntegrated Wireless SolutionCustomized Personal Services

Also known as Mobile Broadband Everywhere.

Features Include: More Security High Speed High Capacity Low Cost Per-bit etc.

Hard to implement

Need complicated hardware

Expensive equipment required to implement next generation network.
