4g Wireless Mobile Communication Networks

This paper is organized as follows: Section II will discuss the evolution of mobile wireless networks, Section III will introduce objectives of the 5G mobile network, Section IV will talk about goals to be evaluated in 5G wireless network communications, and Section V will present some concluding remarks.

It is anticipated that 4G speeds could be as high as 100 Mbps. Thus, 4G will represent another quantum leap in mobile Internet speeds and picture quality. Ericsson confirms that 4G could bring connection speeds of up to 50 times faster than 3G networks and could offer three-dimensional visual experiences for the first time. The following graph represents what has been the typical progression of wireless communications:

Less than a decade ago, the telecom operators in the U.S., Western Europe, and Japan were upgrading their existing networks to high-speed 3G technologies. Now the world telecommunications industry is about the switching to the next-generation super-fast 4G technologies.

Now we can video chat, download data, stream music and videos at a much higher rate than ever before all from our 4g ready mobile devices.

4G networks offer much more coverage than other systems such as Wi-Fi, which forces users to depend upon hotspots in each area you visit. Since 4G offers a coverage of 30 miles and more, users would be assured of complete connectivity at all times.

No doubt, in last few decades technologies involved in the communication systems have been developed exponentially along with attractive features and facilities. Wireless communication system is one of the biggest inventions of the century and its developments can be processed in different terms of generation having approx. 10 years for each one. At every step of each generation is to provide to link with persons at every corner of globe with set of quality services.

- Because of the appropriate amount of spectrum and good network engineering the 4G network will have a high data transfer rate, High speed for downloads and uploads the files over wireless network system. It is 10 times faster than 3G . it support for interactive multimedia, voice, video, and simply reach Internet and continues connected to the Internet without any disturbance.

The usage of cellular data has increased dramatically in the past few years. In order to improve the capacity of cellular networks a number of techniques have been introduced such as massive multiple-input multiple-output (MIMO) and direct device to device communications. This paper concentrates on the coexistence of cellular and Wi-Fi systems in unlicensed bands. It compares two of the more common methods for delivering cellular data traffic over unlicensed bands: traffic offloading and resource sharing. It also discusses a new hybrid method of transferring cellular data traffic, by combining both of the previously mentioned methods. Even though transmitting cellular signal directly over unlicensed LTE (long-term evolution) can achieve higher QoS (Quality of Service) and efficiency than Wi-Fi system, it is important to have effective resource sharing strategies to provide good performance to both LTE and Wi-Fi systems in the same unlicensed band.

Abstract— 5G Technology stands for fifth Generation Mobile technology. From generation 1G to 2.5G and from 3G to 5G this world of telecommunication has seen a number of improvements along with improved performance with every passing day. This fast revolution in mobile computing changes our day to day life that is way we work, interact, learn etc. This paper also focuses on all preceding generations of mobile communication along with fifth generation technology. Fifth generation network provide affordable broadband wireless connectivity (very high speed). The paper throws light on network architecture of fifth generation technology. Currently 5G term is not officially used. In fifth generation researches are being made on development of World Wide Wireless Web (WWWW), Dynamic Adhoc Wireless Networks (DAWN) and Real Wireless World. Fifth generation focus on (Voice over IP) VOIP-enabled devices that user will experience a high level of call volume and data transmission. Fifth generation technology will fulfill all the requirements of customers who always want advanced features in cellular phones. The main features in 5G mobile network is that user can simultaneously connect to the multiple wireless technologies and can switch between them. This forthcoming mobile technology will support IPv6 and flat IP. Fifth generation technology will offer the services like Documentation, supporting electronic transactions (e-Payments, e-transactions) etc.

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

Mobile devices are getting smaller, lighter, and more powerful; they have bigger screens and longer battery life, more features and more capabilities .With the rapid growth of user demands, and the limitations of third generation (3G) mobile communication systems, it is expected that fourth generation (4G) mobile systems are likely to reach the consumer market in another 4-5 years. 4G systems are expected to become a platform capable of providing increased bandwidth, higher data rates, and greater interoperability across communication protocols, and user friendly, innovative, and secure applications. This system will primarily focus on seamlessly integrating the existing systems like GSM, wireless LAN, and Bluetooth. Since 4G is

This research project exhibits a scrutinize of the work done and surveys on 4g remote innovations, which is one of the rising telecom engineering in India, This paper starts with requirement for the 4g innovation in our life and talk about its different benefits, for example, sending a complete minimized plate (around 700mb) in under a moment at a normal rate of 20 mbps.

3G network will not be able to withstand the bandwidth intensive services being planned to be offered by mobile operators, even with only a small number of subscribers utilizing the service within a service area.

4G Smartphone sales have gone through the roof – every Indian telecom operator has already launched or in process of launching their 4G services. However, many of us still think that 4G is just about high-speed data. This is simply not true. Here we try to explain 4G in more detail!

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.
