...4G Wireless Networks Since 2008, fourth generation (4G) wireless networks have been proclaiming faster speeds for internet connectivity than the third generation (3G) networks. However, upgrading to a 3G or 4G wireless network can be quite expensive. Nevertheless, those who find the need for speed and mobility may find that it is worth the added expense. The war is on between the two generations of networks but there is speculation as to which is truly faster and better. The following paragraphs will provide an overview of both wireless networks, and will include a contrast and compare of 3G wireless networks to 4G networks in relation to application and services, user perception, network architecture, and data throughput. The information offered will also differentiate between 4G LTE, 4G WiMax, and 4G WiBro networks based on upload and download speeds, user perceptions, backward compatibility, and service availability.

It uses multiple cell towers sites, each connected through a network, allowed users to travel and even switch cell towers during a call. It was known as the Analog Mobile System (AMPS) and operates on the 824-894MHz range. A Japanese telecommunications company NTT builds their own network in 1979, which became the first 1G network to cover an entire country. In 1981, the Nordic Mobile Telephone network was the first to feature international roaming. It operates in Denmark, Sweden, Finland and Norway. Mobile phones start becoming popular in the United States in the late 80’s and early 90’s when phones were small enough to carry without been in a car or suit case.

...Wireless Networks 4G Wireless Networks Britney Green CIS 500: Information Systems for Decision Making Professor Frank Lazzara November 4, 2012 4G Wireless Networks “Wireless networks use packet switching and wireless networks. Patching switching is when the path of the signal is digital and is neither dedicated nor exclusive. Routers are devices that forward packets from one network to another network. Packets occur when the network breaks a file or e-mail message into smaller blocks of specific size. Wireless routers are actually wired routers with wireless access points (WAP) built in. It provides both wired and wireless at the same time”. (Turban & Volonino, 2011) Third generation also called 3G; of cellular telecommunications technology supports multimedia and broadband services. Broadband means fast transmission speed. It is faster than the 1G and 2G. The third generation networks have far greater ranges because they use large satellite connections that connect to telecommunication towers. The fourth generation is called 4G. 4G mobile network standards enable faster data transfer rates. (Turban & Volonino) Right now 4G is the latest generation of wireless data technologies. It carries average download rates of 3 Mbps or more. “In contrast, today's 3G networks typically deliver average download speeds about one-tenth of that rate. The 2G and 3G started separately with their own purposes; soon both will be converted to the 4G network”...

...advanced communications and information technology to large businesses and the government customers worldwide. The merger of Bell Atlantic and GTE was valued at more than $52 billion. The purpose of the merger was to build a dynamic company that is capable of competing in the industry’s top-tier level. It took two years for the merger to close. In the meantime, Bell Atlantic and Vodafone Air Touch, now Vodafone Group, announced their agreement to create a new wireless business. The new “Verizon” brand was launched on April 3, 2000, after a six month wait for regulatory approval, and began operating as Verizon Wireless on April 4th. GTE’s wireless operations joined Verizon Wireless thereby creating the nation’s largest wireless company. “Verizon then became the majority owner (55 percent) of Verizon Wireless, with management control of the joint venture” (Varettoni, 2013, p. 3). Upon entering into an agreement to acquire Alltel, Verizon had to meet some conditions of the acquisition. Verizon had to divest overlapping wireless properties in...

...deal to buy majority control of Sprint Nextel will unite Japan’s fastest-growing cellphone service provider with one of the United States’ most troubled. The idea is to provide Sprint with a stronger, deeper-pocketed partner that can help finance its network overhaul and, eventually, pursue additional mergers. But SoftBank, an Internet and communications company, is making a risky wager that it can break the dominance of Verizon and AT&T in the United States the way it did a similar duopoly that long reigned over the Japanese market. “SoftBank brings so much more to Sprint than money,” Daniel R. Hesse, Sprint’s chief executive, said on an analyst call. “This investment provides the opportunity to benefit from the knowledge and expertise of a leader in mobile Internet technology with a proven track record of challenging larger incumbent carriers.” Together, the two companies would have $80 billion in revenue and $18 billion in earnings before interest and taxes. And they would nearly double Sprint’s customer base to 96 million, giving the company greater purchasing power. SoftBank’s founder and chief executive, Masayoshi Son, was blunt in his goal: creating the biggest and fastest wireless network in the United States. It is the strategy his own company is pursuing in Japan, aimed at drawing in users of the latest smartphones. Sprint is only beginning to roll out its next-generation Long Term Evolution network, trailing Verizon Wireless and AT&T. “U.S. citizens don’t...

...Assignment 2: 3G wireless networks and 4G networks sweetie Professor: CLIFTON HOWELL CIS 500 February 03, 2014 INTRODUCTION For one to compare and contrast 3g versus a 4g network, we first have to define what a wireless network is. Radios are considered to be the most popular for wireless technologies. Wireless communication is transferred between multiple points which are not connected to an electrical conductor. Wireless is playing a big part in the cellular network communication field. Literally, on all the channels on TV it’s impossible to go 3 minutes without seeing advertisements from Verizon, AT&T, T-Mobile, and Sprint claiming to be the best network provider. Each cell phone provider promote their own version of 3g and 4g networks. Carriers do this to draw the attention to endorse their services and to bring in new customers. As a result, it makes it very difficult for consumes to make a choice between the competitors. Consumers make their choice between providers based upon the price and coverage which are both vital to most consumers. With all the promotions and dramatic advertising it can be hard to know the truths about each wireless company. In this paper 3G and 4G networks will be compared and contrasted, 4G LTE, 4G WiMAX and 4G WiBro networks and competition will be identified. Lastly, this paper will identify why the competition between the 4G LTE carriers has been so fierce. 3G and 4G Networks Technology has allowed advance speed to...

The first areas examined are service and applications. Third-generation (3G) networks consist of CDMA 2000, UMTS, WCDMA, and various others. Fourth-generation (4G) technologies include WiMAX, HSPA+21/42, and LTE, of which many consider LTE to be the only “true” 4G network (Segan, 2013). The introduction of 3G technologies heralded a wide range of possibilities to include the ability for user to wirelessly stream audio, video, visual calling and conferencing, and various mobile multimedia functions to include more streamlined E-mail and general web browsing, online banking, basic video games on demand, mobile TV, and location-based services (4Gon Solutions, 2012). 4G application offerings include four main categories: Localized/Personalized Information, Communications, Organizational, and Entertainment (M-Indya, 2012). Localized/Personalized Information applications will offer users the ability to browse various news outlets, more accurate and improved locational servicers, more enhance mobile commerce (i.e. mobile...

...networks survive. Verizon currently dominates the market and services 31.9% of American mobile users. The company was established in 2000 as a joint venture between Vodafone and Verizon Communications. One of the Verizon’s largest acquisitions was the purchase of Alltell Wireless in 2009 for $28.1 Billion; this purchase expanded their network coverage and increased their market share. Verizon operates a CDMA Radio network which does not require the use of SIM cards. The company’s service quality is a competitive advantage and Verizon invests about $5.7 Billion per year to expand and upgrade their network services. Verizon boasts “America’s largest and most reliable network” and has over 160.3 Million subscribers. They recently added the iPhone to their product line in early February which has allowed the company to take a significant portion of sales away from AT&T. Verizon is one of the most expensive networks and appeals to customers who are willing to pay a premium for advanced network technology. In other news the FCC has accused Verizon of illegally adding charges to customers’ bills. The company was ordered to repay $52.8 million in funds back to customers in early October of 2010. AT&T wireless is the second largest service provider with 98.6 Million users in the U.S., Puerto Rico and Virgin Islands. The company has a more economic pricing structure and promotes rollover minutes. AT&T operates a GSM network, which is...

...percent of U.S. mobile carrier Sprint Nextel Corp. for $20.1 billion in the largest ever foreign acquisition by a Japanese company (Walker).” This is a mergence between the Japanese third biggest mobile carriers and U.S third biggest mobile carriers. Some investors believe this action will disrupt U.S Market and make Sprint competitive with two traditional communications giants AT&T Inc and Verizon Wireless. As we all know, Sprint is suffering a hard time now with huge debts. One article points out that Sprint has struggled in recent years to compete with Verizon and AT&T. The company has $21 billion in long-term debt, and has launched a costly network restructuring and signed a long-term contract to buy $15.5 billion worth of iPhones from Apple Inc. over four years (Walker). On the other side, Softbank are also not financially healthy. Softbank spends $20 billion buying Vodafon Japan subsidiary on 2006 and takes 5 years to pay off the debt. Besides, Softbank just announces a 2.2 billion emerge plan with eAccess this month. So Softbank’s statement of assets and liabilities may disappoint investor for a long time. So most people may question that whether Softbank can save Sprint and stop Sprint’s declining tendency. Like when Softbank bought Vodafon in 2006, many economics thinks this deal is way too expensive and not worthy. In my idea, I think this deal may benefits both Softbank and Sprint. And Softbank has the ability to rebuild Sprint. First, the president of...

...After reading the case study, I firmly believe that five potential commercial applications of mobile WiMax would be to create a quicker, faster and stronger wireless network, better use and integration of cell phones in automobiles and other forms of transportation, an easier means to start or create networks, bringing wireless internet to more public places, and to improve in video messaging and email. 3. Clearwire went public in March 2007 at an initial price of $27.25. As of April 2010, the price was $8.00. Go Online and research the company to find out what happened to its share price. Explain why its share price has dropped. Clearwire’s share price dropped from $27.25 to $8.00 in 2007 because Clearwire and Sprint merged their wireless broadband unit into sprint’s 4g WiMax network with Clearwire’s WiMax broadband network. 4. AT&T and T-Mobile have endorsed HSDPA, but it does not have the same potential maximum transmission rates. Rather than jump on the WiMax bandwagon, those companies plan to deploy a different technology called Long Term Evolution (LTE). Search the Web for LTE versus WiMax comparisons and compare and contrast these two technologies. Long Term Evolution (LTE) is the standard for wireless transmission of high-speed data. The main mission of Long Term Evolution is to increase the wireless data networks speed and capacity by using new technological hardware. WiMax, is also known as Worldwide Interoperability for Microwave Access. WiMax is the...

...Wireless Communication Providers During the latter half of the 20th century to the early years of the 21st century, cellular phones have become a massive trend in our culture. Cell phones originally were seen as novelties that weren’t necessary and were items that only the wealthy wasted their money on. The majority of people have incorporated cellular phones into their everyday life. From 2006-2010 subscriber numbers increased an estimated 5.9% per year, resulting in increases in industry revenue at an average annualized rate of 3.9% (Brumley). Cell phone would be nothing without a cellular service provider. In order for you and I to have teleconferences, talk with family and friends, or hold any type of conversation while on the go without being tied down by wires cellular service providers offer transmission services to us through radio frequency signals rather than through end-to-end wire communication like land lines. These services can sometimes be complemented with data, messaging, and GPS packages and even more. Due to our constant need to be connected with each other cellular service providers are continuing to grow in the domestic market. For an industry that started less than 30 years ago it had revenues of about $138 billion in 2007 and currently has an estimate of 238.2 million subscribers. Wireless services were based on cellular technology in the beginning. Cellular technology divided geographic regions in cells and sent analog signals to customers...

Unfortunately, 4G LTE is largely unavailable in rural areas and the cost of the service is substantially high, forcing most users to use a 3G service until these factors change. While the technical differences between 3G and 4G service can be a little confusing, buyers can compare upload and download speeds, customer perceptions and service availability to determine what service is best for them. 3G and 4G Wireless Networks 3 For consumers, the differences between a 3G network and a 4G LTE network can be a little confusing but there is some good information available to the discerning shopper. For those who wish to learn a little more about 3G and 4G technology, examining what each network does and does not offer, can help them decide which service is best for them. 3G and 4G Networks Both 3G and 4G networks offer similar services and applications to their customers.
