4g what is the technology

Mobile networks have evolved tremendously in last 3 decades. Today, 4G technology is getting ready to storm the markets. Not only that, research on 5G technology has already begun. Evolution of Mobile Technologies. Zero Generation Technology 0G. Being the predecessors of the first generation of cellular telephones, these systems are called 0G zero generation systems.

First Generation Technology 1G. In 1G, Narrow band analogue wireless network is used; with this we can have the voice calls.

These services are provided with circuit switching. Second Generation Technology. It provided the facility of short message service SMS unlike 1G that had its prime focus on verbal communication.

A typical 2G G. Typical average data rate of GSM is 9. The bandwidth of 2G is KHz. It allows the clear and fast transmission of data.

Also, there are no additional charges for utilizing this technology. Uses 9 Modulation coding schemes MCS Modulation bit rate is kbps. It offers data rates of kbps, theoretically up to Third Generation Technology 3G. The aim of 3G is to provide these services anytime, anywhere throughout the globe, with seamless roaming between standards.

It offers large capacity and broadband capabilities. It has greater network capacity through improved spectrum efficiency. The data are sent through Packet Switching. Voice calls are interpreted through Circuit Switching. It is a highly sophisticated form of communication that has come up in the last decade. It is an enhanced version and the next intermediate generation of 3G UMTS allowing for higher data transfer speeds.

This high data rate is enabled by use of adaptive modulation can coding AMC , hybrid automatic repeat-request HARQ , and fast packet scheduling at the access point.
