Advantages And Disadvantages Of 4g

If you were implementing a low-cost wireless network that had to cover a very large area and support only a few users, the use of 802.11g technology would be a very good option. 11g technology operates at the 2.4Ghz range which allows for access points to provide signals up to 300 feet. The 2.4GHz signal also has lower rates of signal loss from obstructions. This means that a fewer number of AP's would need to be purchased for complete are coverage. Also, by providing throughput of up 54Mbps it could easily support bandwidth needs of multiple users who require minimal bandwidth. This would be the case of a warehouse or large department store where the applications would not place major demands on network resources.

The accuracy of this technique is very low due to the fact that cell towers can support ranges of 35 kilometers or more.

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

5G is the fifth generation wireless broadband technology based on the IEEE 802.11ac standard. 5G is provide high speed then 3G and 4G. 5G operates on 5GHZ signal and set is to offer speed up to 1 GB/s.

In addition, in the 1980s, the first network (1G) was introduced to people on a large scale but its use was only restricted to the country’s boundaries. The second generation (2G) network was digital, not analog and its development began in the late 1980s.   Then, the marketing demand began to shift from 2G to 3G in 2002. Compared with the previous networks, the data and voice communications capabilities of 3G have increased significantly.

5G Wi-Fi: The 5th generation of Wi-Fi is here. (2012, July 12). DIGITIMES daily IT news. Retrieved February 1, 2013, from http://www.digitimes.com/supply_chain_window/story.asp?datepublish=2012/7/11&pages=PR&seq=201

Against this backdrop, Sprint has made significant changes in the last 2 years to embark on a turnaround plan of epic importance to its future. The industry is preparing for another major technology upgrade to 5th Generation (5G) which will bring about even faster data speeds, greater coverage, and an exponential expansion of the Internet to many more devices beyond just

By upgrading our systems with fiber, little cells, in-building frameworks, reception apparatuses and other limit boosting advancements, we 're not just expanding our capacity to meet today 's surging interest for remote information and video; we 're likewise getting our system prepared for 5G slight innovations. It has the possibility considerably to increment the throughput and responsiveness of remote systems. As we have done with past change shifts in system design, Verizon plans to lead the path to the 5G world and has as of now worked with innovation accomplices to build up the principles also, advertise applications that will drive arrangement. We hope to direct trials of 5G in 2016 and move forcefully to business method from that point. We trust that 5G will be the establishment for another rush of development and purchase advantages in such regions as versatile video, savvy urban communities, and different applications work in progress.

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.

It’s very important to determine the device and application requirements based on bandwidth, protocols and frequency. In wireless network, bandwidth, protocols and sometime environmental conditions affect the speed of the channel so we need to calculate the aggregate throughputs before designing the network. Today, users carry Wi-Fi devices such as notebooks, laptops, tablets and Smartphone’s so total throughput must be calculated by estimating number of connections rather than the number of the seats. Some common wireless networking standards such as 802.11a/b/g/n invented in the IEEE association must be supported by wireless network. For better performance and for faster devices (802.11n devices), dual-ratio access points should be deployed. Table1 [3] illustrate the different IEEE standards and throughput.

The increasing usage of networks especially wireless networks for different applications, has moved to focus towards the design and optimal routing of the networks in the modern life. The use of wireless networks instead of wired networks solves many issues in real life. These challenges includes the Mobility, signal fading, power and energy, data rate, security etc.

What is 5G network? And when was it developed? Well Lets first explain the meaning of the G in the 5G , Well G means Generation , This is the 5th generation of Mobile communications and networking , The first Generation 1G Was introduced in 1982 and it could only support calls and it was quite flawed , as there was no security and was easily hack-able , then in 1992 2G or Known as Edge was Introduced to fix some of the flaws 1G networks had Including support for text messages and slow internet of about 512 kb/s which was quite superb at its time but quite slow if we are comparing with today’s standards. Network engineers have been trying to fix these problems , and after the breakthrough of the internet and some social media websites like MySpace and email messaging in business , 3G was introduced in 2003 , with theoretical downloads speed of 7.2 Mbps which was respectable at the time , of course it took phones quite some time to adapt to the new standard which wasn’t very popular

There has been continuously increasing demand for high data rates and mobility required by new wireless applications which needs to be addressed by 5G networks.

Compared to wired links, the reliability, scalability, efficiency and capacity of wireless links are often less. The communication channel is subject to noise, fading, interference and has less bandwidth than a wired network.
