Network Speed - 4G Technologies Essay

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.

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.

When we think of a cellular network it is not a completely wireless network. No one has completely independent wireless network.

The bandwidth required for voice, video and streaming data are growing for future communication networks. It can be expected and provide the future generation Telecommunication network will be an integrated and secured by All-IP network. Research institutes are devoted and played a crucial role to deploy IP protocols in mobile communication core network and services. The IP multimedia subsystem (IMS) is a network subsystem proposed by 3GPP. The IMS concept is to merge alltelecommunication technology, wireless and wired networks under the All-IP environment to provide a more extensible, synchronized, interactive multi-media service in 3G and future 4G networks. IMS can be regard as the trend for prospect wireless communication networks. The IMS offers three main functions in the core network: providing quality of service (QoS) for services providing the extensible charging mechanisms, providing user integrated services, and the standard architecture make the third parties could provide different rich

One of the most heavily advertised areas of technology in the United States currently is 4G technology. Every commercial and advertisement promises fast speeds, great coverage, and exceptional service altogether. However, the competition proves to be extreme and unbalanced. Since its introduction on Sprint’s network, 4G, or fourth generation cellular technology, has revolutionized both the telecommunication arena while spilling into other technological fields. There is no end in sight for the relentless competition of expanding 4G technologies as coverage and network speeds continue to increase. Currently, 4G technology is offered by all major telecommunication carriers in the United States: Verizon, AT&T, T-Mobile, and Sprint. However, the term “4G” has been loosely used. The best example of this can be associated with Sprint.

In a bid to sustain the achievements made in the era of 3G technologies and foster efforts of economic recovery, the United States of America should stay abreast with the rest of the world by deploying 4G technology in its communication infrastructure. Being a world leader in the broadband applications, companies in the United States of America enjoy the efficiencies that come alongside the platform of these

5G aims at building hybrid networks utilizing both the Wireless LAN concept and WAN design. Thus, the world would have base stations everywhere providing ubiquitous network coverage to users at high speed. For example, a user walking on road is browsing internet using GPRS (General Packet Radio Service-WAN design). The moment he enters a mall with Wi-Fi (LAN design), seamless hand-over from GPRS to Wi-Fi would take place without the user’s

In networking technology, wireless is the term used to describe any network where there is no physical wired connection between sender and receiver, but rather the network by radio waves or micro waves to maintain communications. The evolution of technology specially in mobile technology is the most and fast developing, that era starts from 1G in 1980s and it is replaced by a continuous emerging of next generations. To compensate the drawbacks of each previous generation next generation with lot of new applications is introduced. Now it is fourth generation that is 4G, beyond 4G now researches are going on about 5G and it will come into existence by 2020s. In the near future, i.e., beyond 4G, some of the prime objectives or demands that need to be addressed are increased capacity, improved data rate, decreased latency, and better quality of service. To meet these demands, drastic improvements need to be made in cellular network architecture. This paper presents the results of a detailed survey on the fifth generation (5G) cellular network architecture and some of the key emerging technologies that are helpful in improving the architecture and meeting the demands of users. A detailed survey is included regarding all wireless generations especially concentrated on 5G by research groups and

This article presents an architecture vision to address the challenges placed on 5G mobile networks. A two layer architecture is proposed, consisting of a radio network and a network cloud. Three main concepts are integrated; ultra-dense small cell deployments on licensed and unlicensed spectrum, NFV and SDN and intelligent use of network data. This article proposes a novel 5G mobile network architecture that accommodates the evolution of communication types, end-user behaviour, and technology, trends in end-user and technology that motivate the challenges of 5G network and articulation of a 5G mobile network architecture.

Audience for this topic can be the anyone who has some basic knowledge about networking. This Document provide detailed information about quality of structure (QoS) in wireless networks and cellular networks.

The advancement in mobile devices and wireless technologies has enabled the provisoning of services more flexible and diverse [5-7]. On one hand, The manufacturers of mobile devices have recently achieved breakthroughs to extend mobile devices’ capabilities

During this period cellular or mobile communications has begun to rapidly grow. The amount of time spent on network allocation, concentration, usage, and maintenance for these newer technologies were starting to become more complicated.

The revolution of network technology began several years ago, with fourth generation (4G) network being the recently technological innovative of the internet world. Therefore, 4G networks is the fourth generation wireless network, which set the stage for broadband mobile communication that will succeed the third generation (3G) network which is currently in use in some many countries around the globe. It also provides mobile ultra-broadband internet access with USB wireless modem to laptops and even Smartphone ( HYPERLINK "https://profiles.google.com/118388133610479779997" Sascha Segan, 2011).
