Difference between 3G wireless network and 4G wireless network Sajid Hussain , Asadullah Department of Computer Science University of South Asia 47 Tufail road, Lahore cantt, Pakistan [email protected] , [email protected] Abstract : The differences between 3G and 4G are done on the basis of following terms: Definitions, Background differences, Speed, Bandwidth and Frequency Band, Architecture, Applications, , QoS, Features and capabilities . Keywords- 3G,4G,UMTS,LTE,WCDMA,CDMA 1. Introduction : 1G,2G,3G and 4G are the mobile telecommunication technologies. where “G” stands for generation. 1G first generation, 2G second generation, 3G and 4G third and forth generation respectively. Up gradation of mobile cellular has revolutionized the way people communicates. If we talk about how the communication style of people got changed with respect to the change in mobile networks generation. Let’s talk from the beginning. The 1 st generation (1G) of mobile network fulfilled the basic voice communication. With the invention of 2 nd generation users of mobile technology met with capicity and coverage. Later the 3 rd generation (3G) given people access to high speed and opened the gates of truly “mobile broadband” experience that had further realized in 4G. 4 th generation gave access to a wide range of mobile telecommunication. 1.1: Basic definitions of 3G and 4G : 3G stands for the third generation. It is named as such because it is the third generation of wireless telecommunication. It is the successor of 2G and 2.5G. 3G technology is founded on the International Telecommunication Union group of standards which belongs to IMT-2000(International Mobile Telecommunication 2000.) 4G stands for the fourth generation. It is named as such because it is the fourth generation of wireless telecommunication. A 4G system provides its user an ultra-broadband internet access with higher data rate. 2.Background difference : 3G technology which was founded on international Telecommunication union
group of standard IMT-2000 uses W- CDMA (Wideband Code Division Multiple Access) technique. It allows the network operator to provide its user a big range of latest services. whereas 4G technology which was started in 2009 gives user a new experience of downloading speeds and capabilities . 3. Speed : 3G third generation offers maximum real world speed of 5.8Mbps to 14.4Mbps. But a speed of 300Mbps on 3G can be achieved in a controlled environment. Whereas 4G goes up to 100Mbps to 1Gbps.
