transferred only voice data without being encrypted. The sound quality and the speed of transfer were in poor conditions as well. However‚ over the last 20 years‚ the quality of communication in China has increased significantly with the development of 2G‚ 3G and 4G communication technologies. In 1990s‚ the 2G technology was introduced. This abbreviation refers to digital voice systems‚ i.e. systems that transmit information via voice signals‚ which replaced early analog phones. 2G may be considered

This paper will compare and contrast 3G wireless to 4G wireless networks and discuss the competition between the two carriers 3G and 4G networks can be compared in four different areas: services and applications‚ network architecture‚ data throughput‚ and user perceptions. The 3G and 4G networks have some similarities but differ in many ways. 3G is short for third generation of cellular telecommunications technology (Turban‚ Volonino). 3G supports multimedia and broadband services‚ do

The short fall of 3G networks is clear‚ it’s just not fast enough‚ offering 384kbps doesn’t meet the requirements of what the end user has come to expect these days. Some people see 3G as a stop-gap‚ until a fully integrated IP network is created; some countries have even chosen to bypass 3G and head straight to 4G‚ a method which has its advantages‚ and its disadvantages II.A. 4G HISTORY At the end of

Email-ID: baldevpce39@poornima.org 1. ABSTRACT LTE stands for long term evolution which is used for 4G technology. In 4G technology speed of data is increased up to 100 Mbps for downloading and 50 Mbps for uploading. LTE is advance technology of 3G in which OFDM is used for downloading and SC-FDM is used for uploading of data. In this paper we are understand that what technology already used for mobile communication and why new technology is necessary? And what is the advantage of LTE over GSM

Lab 2 2.2.1 The mean arrival rate of the number of users in a particular cell making a call in the busy hour and the time interval of those calls is calculated. Every user makes a call in an interval by using the uniform random number. If this number exceeds 1-mean arrival rate or is equal to the mean arrival rate‚ then a call is generated which is referred as poisson threshold. 2.2.2 In this case the green line indicated the poisson threshold. When the customer uniform random number exceeds
