4g Wireless Mobile Communication Networks

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.

In terms of architecture, it has been very challenging to provide platform, and ability to render service with high availability from the providers of the first generation (1G) networks to 4G

Today we are in Fourth Generation; it is categorized based on its characteristic services and features like transmission signals, data transmission rate, bandwidth frequency and nature of the services provided. First generation (1G) is introduced in 1980, so each generation had been comes at the end of every decade. First generation used analog signals, circuit switching and FDMA with 30 kHz channels occupying the 824MHz 894MHz frequency band .First generation supports only voice transmission .The data was not reliable; there were interrupted communication and few other problems in First Generation [1]. Second Generation (2G) technology was established in 1990, which used digital signals for transmission and two digital modulation schemes TDMA and CDMA with circuit switched network . Second Generation uses the existing radio spectrum to provide the services. It was developed to overcome the previous generation’s drawbacks, and to have data and voice transmission. But this generation also has few drawbacks like

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.

Every day the wireless communication is getting more advanced comparing to what is was yesterday. Every generation of mobile communication get advanced with a higher speed, frequency band, better connectivity, security and high data rates in transmission. For all these reasons, it’s clear how the 4G is success more than the 3G networks, and the same thing will happen to the 4G after lunching the 5G in the near future. In this paper, I will try to describe the 4G networks and 5G networks in contest of future of mobile communications. What are their drawbacks and what are the main differences between these different generations along with the issues that make the new network take over that network.

The world today is so deeply evolved with the use of technology a resource. The future of mobile data system has always been a mystery and a question of excitement due to the fact of how different is it going to be from the present generation of mobile data. Mobile data system has been a developing area over the years starting from analogue phone calls to All Internet protocol and communication protocol. The idea for a better and for a more successful next generation of mobile data was inspired from the previous generation. Also, with the development of various apps in smartphones and tablets with data services, it made a plus point in the people’s electricity usage or having to turn of electronic appliances. The term “5G” is the next big

Introduction The world lives a large evolvement in all life aspects. Everything moves in the comfort direction. One of these aspects is the technician aspect and it is an important part of everyone 's life as every thing around you become technician. In your room there is a TV, mobile, laptop...etc. Even most of kids ' toys became in need to a remote control. The wireless technology means no need to wires or cables. Wi-fi and Bluetooth are examples of that. Mobile wireless industry now is in the head of all industries due to the increasing in mobile usage day after day. It passed through several generations until it reached this great evolvement which we see now. It started with the first generation 1G with analog communication. In the second generation 2G the digital messaging was added to the analog communication. In the 3G, both calls and messages became digital. In the 4G –which we have now- the improvement was in the usage of a large bandwidth. The generation which is expected to appear is the 5G. The 5G is purely based on the 4G and will give a huge level of bandwidth which we cannot imagine. Furthermore, there are two predicted generations 6G and 7G. The 6G will be a satellite based network with speed up to 1 GB. This leads to the space roaming problem which shall be solved by the 7G. The report is organized as follows. First and Second section provides literature review of past and current mobile communication generations from first generation (1G) to fourth

5G networks will deliver more richer content in real time ensuring the safety and security that will make the wireless services more extensive in our everyday life. Some example of emerging services may include high resolution video streaming (4K), media rich social network services, augmented reality, and road safety [6]. According to Cisco mobile data traffic forecast,

The evolution of mobile telephone system can be classified into different generation based on the level of maturity in technology. This classification does not depend on any standardized facts. The purpose of this paper is to provide the history of mobile communication and provide an overview of 4G and its features, architecture, key technologies and challenges.

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. [4]

4G allows IP-based voice, information and streaming multimedia at higher speeds and offers no less than 100 Mbit/s with high versatility and up to 1GBit/s with low portability (traveling). Various advancements thought to be 4G measures incorporate Long Term Evolution (LTE), Ultra Mobile Broadband (UMB) and the IEEE 802.16 (WiMax) standard. At the point when utilized as a part of MIMO frameworks it would have the capacity to give high information rate up to 100Mbps furthermore give QoS and Security administrations to end clients. The 4G goal is to meet difficulties displayed by the perpetually

The recent introduction of 3G mobile services in India have however brought in enhanced data and voice transmission and are welcome signs in the improvement in mobile communication technology. The essay deals in-depth with 3G wireless technology and the difference with its successors (3.5G and 4G) and predecessor (2G).

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

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.
