3g Wireless Communication Technology

Communication is as old as the first human interaction and it is fundamental to our experiences. As technology changed over time, so did the ways we communicate. At first, people communicated with spoken words in person. Then, people wrote letters to each other so they could talk to each other when they were in different locations. The telephone was the first technology that allowed people to speak out loud to others far away. The technology then evolved so that those telephones could be portable and personal, so that people could move with their technological communication devices.

The cellular technology has developed a long way from its existence in the early 1980’s. In the past few decades it has grown into one of the biggest market with the rise of cell phone users, the cellular network providers and cell phone makers have grown in immense amount. Cellular technologies have evolved from first generation (1G), second generation (2G), third generation (3G) and to its current technology which is fourth generation (4G) which is also known as Long Term Evolution (LTE).

The purpose of the paper is to focus on the development of wireless mobile telecommunication. Firstly, cellular

The existing microwave network support TDM/ATM and provides a peak downlink of 28 Mbps. Most of the radios existing are PDH and SDH for supporting the legacy 2G and 3G networks. The modulation schemes used are lower in order reaching to a maximum of 128 QAM in smaller channel widths i.e., 7 MHz or 28 MHz. Presently, in India, allotment of carriers for microwave

The purpose of the paper is to focus on the development of wireless mobile telecommunication. Firstly, cellular network technology is introduced to understand the basis of wireless mobile telecommunication. And then the history evolvement of mobile telephone systems is investigated to help know the background of fourth-generation wireless communication (4G). Finally, the standard of 4G, different categories, the spread spectrum radio technologies as well as potential benefits and problems that come with it are discussed. Especially, LTE standard is further explained, including FDD-LTE, TDD-LTE and LTE advanced.

As the basis for enabling multimedia communication, broadband services naturally calls for media convergence that will be based on packet transport to promote the integration of various media on different behaviors. A lead to a demand for similar services in mobile communication environment is expected to increase with the growth in broadband services like cable, DSL, optical fiber access systems and office or home LANs. 4G service application characteristics will likely enable broadband service to be low cost, high coverage of wide area, and wide variety of service capabilities.

5G technology stands for fifth Generation Mobile technology .From era 1g to 2.5g and from 3g to 5g this world of telecommunication has seen a number has seen upgrades along with improved performance with every passing day. This fast revolution in mobile computing changes our everyday life. That is way we work, associate, learn and so on. This paper also focuses on all the preceding generations of mobile communication along with fifth generation technology. Fifth generation network provide very high speed broadband wireless connectivity. In fifth generation researches are generally made on development of world wide wireless web(WWWW), dynamic adhoc wireless networks (DAWN) and real wireless world. The most critical advances for 5G technologies are 802.11 wireless Local Area networks(WLAN)and 802.16 wireless metropolitan area networks(WMAN).The Fifth generation concentrate on VOIP –empowered gadgets that client will experience a high level of call volume and data transmission. 5G technology will satisfy all the necessities of clients who always want progressed peculiarities in mobile phones. The main feature in 5g mobile network is that client can simultaneously connect to the multiple wireless technologies and can switch between them. The anticipated versatile technology will help Ipv6 and flat Ip.fifth

GSM (Global System for Mobile communication) is a digital mobile telephony system which is TDMA based wireless network technology developed widely in Europe and other parts of the world. GSM uses a variation of time division multiple access (TDMA) and is the most widely used of the three digital wireless telephony technologies (TDMA, GSM, and CDMA). GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot.

As the GSM uses the combination of Time and FDM, the mobile is used to demultiplex the given channel and also it is responsible for accessing the channel more effectively and efficiently. The mobile device is used to transmit and receive the required data within in a given time frame and with if a give condition. With the help of mobile devices, there are many other services offered by the GSM to enable ad to support more efficient data transmission. These services can be SMS, MMS etc. All these services can only be accessed with the help of mobile devices which supports may other multimedia features like live calling, video calling etc. Every day,

3G could finds an application in wireless voice telephone, mobile internet access, fixed wireless internet access, video calls and mobile TV. 3G show all collection of technology to

With the rapid development of communication networks, it is expected that fourth generation mobile systems will be launched within decades. Fourth generation (4G) mobile

GSM stands for Global System for Mobile Communication and is an open, digital cellular technology used for transmitting mobile voice and data services.

According to Chandrasekaran (2005), the 4G mobile communications has arrived, introducing a variety of services, use of different standards, different terminal services to deploy heterogeneous networks. (Chandrasekaran, 2005) The method involves the use of all single-use devices, designed to

This project report is being presented on GSM NETWORK OPERATION where are studying different nodes like MSC, BSC, RNC and other GSM node .We are also being given a demonstration in the Data Center where servers are present. The GSM is a method of cellular communication which has a facility of voice communication and also data .The transmission of data was not good because data rate or speed that is why 3G was developed for delivering of data.
