Much of the lte standard addresses the upgrading of 3g umts to what will eventually be 4g mobile communications technology a large amount of the work is aimed at simplifying the architecture of the system, as it transitions from the existing umts circuit + packet switching combined network, to an all-ip flat architecture system. An introduction to 4g technology the fourth generation of wireless standards for cellular systems is 4g, the planned successor to the 3g standardthe itu (international telecommunications union) has specified that the peak speed requirements for the 4g standard are to be 100mbps for a mobile connection (such as in a car) and 1gbps for . 4g mobile communications submitted by: pawan kr mishra btech ec 4th year these 1g cellular systems still transmit only analog voice information mobile system generation first generation (1g) mobile system: the introduction of cellular systems in the late 1970s and early 1980s represented a quantum leap in mobile communication.
To be advertised as 4g, a network must offer peak data rates of at least 100 megabits per second for high mobility communication (users in cars, trains, etc), and at least 1 gigabit per second for low mobility communication (pedestrians and stationary users). The approaching 4g (fourth generation) mobile communication systems are projected to solve still-remaining problems of 3g (third generation) systems and to provide a wide variety of new services, from high-quality voice to high-definition video to high-data-rate wireless channels.
