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 voice and data and it is known as a 3G network. It is also known as the third group or third generation of cellular telecommunication. 3G speeds are faster than 1G and 2G networks examples includes multimedia photos and applications. The wide area cell based is the 3G network architecture. CDMA 2000, UMTS, EDGE just to name a few are the applications and services operated on a 3G network. User Equipment (UE) and the UMTS are the two most important parts of the 3G network. The Terrestrial Radio Access Network is the brain of the network. The UTRAN and the UE make up different layers. The medium access, the physical layer, the radio link layer and the radio resource layer are the lower layers of the network architecture. For most carriers who uses a 3G network, the 3G data throughput can support up to 3.1 Mbps with average speeds ranging from 0.5 to 1.5 Mbps. 4G is the evolution from 3G for mobile devices and mobile communication. 4G is the fourth generation of the mobile technology standards. In these days, 4G is used by most cellphone providers worldwide. Most consumers take advantage of a 4G network to use the fast speeds. Using a jet pack or a wireless modem for a laptop or desk top are the benefits of consumers wanting to take advantage of the 4G. The data throughput for a 4G network is 2Mbps to 12Mbps. The 4G network architecture is a combination of wireless LAN and Wide area. The applications and services for a 4G network are Wimax2 and LTE-advance.
So the million dollar question for consumers and their perception of a 3G and 4G network is how much faster is 4G versus 3G? The network speeds are determined how the network is structured. Providers such as Verizon Wireless which uses CDMA networks have stretched the limits on how fast their 3G network operates. The benefits of a 4G network for cellphone providers allows them to comprise data transmission speeds up to 3 to 4 times faster than a 3G network. Now here is the kick, AT&T and T-Mobile uses a GSM network and still have room to improve their 3G network to reach increasing speeds of a 4G network. (LTE) Long term evolution is intended to be backward compatible with HSPA and GSM. In layman’s term when a mobile device is outside of the 4G network it can work on a 3G network of course expecting the mobile device being capable of requisite radio technologies. Currently Verizon is the leading company in 4G technology. Verizon LTE is available in 190 cities covering 200 million American subscribers.
Digicel and LIME use WiMax and HSPA which falls under the 4G category. According to authors Turban and Volonino WiMax is a group of broadband wireless communications standards for metropolitan area networks. Sprint, Comcast and Time Warner Cable mainly use WiMax to deliver wireless broadband (Turban/Volonino, 2011). WiMax data transfer is up to 70 Mbps.
WiBro is also known as wireless broadband located in South Korea. Currently WiBro is offered in more than 80 cities. The primary function is to provide handover functionality and to integrate wired and wireless networks to enable seamless service anytime, anywhere (Turban/Volonino, 2011). WiBro data transfer rates are up to 50 Mbps.
COMPETITION BETWEEN THE 4G LTE CARRIERS
In today society, smart phones have become the significant feature of day to day living. As a result cell phone companies have no choice but to respond to the enormous market. Because everyone wants the finest on the market mobile devices quality has changed and raised as manufactures attempt to make products that are better than their competitors. The primary reason why competition is fierce between cell phone carries is because of the pricing. Due to the aggressive competition cell phone providers who give mobile devices is also impacted. Cell phone providers offer different pricing options and levels to stay competitive. Ultimately, wireless technology can give a cell phone provider a competitive advantage through increased productivity, better customer service, and more timely communication and information exchange.

CINCLUSION Verizon is in the lead for more reliable and expansive network services because of the early adoption of the LTE network. Usually Verizon offers better uploads and downloads out striding the other competitors such as AT&T. WiMax and HSPA have progressed over time in reference to speed. All 4G networks are not equal. LTE is by far the best and fastest network available. Your area determines the coverage and speeds. Speed is not at all times the most important features for customers. Most customers will choose the providers based upon the cost and customer service. The way technology has advanced receiving calls and text messages is no longer a primary use for smartphone in today’s world.

Volvo’s data Warehouse has multi-terabytes of data from the hundreds of sensors and CPU’s that are embedded throughout the car as well as data from customer relationship systems. The Cloud platform allows implementing and evaluating real-time information systems to transform data into knowledge. This will give Volvo a competitive advantage over other car companies and allow their offices no matter the location to immediately take advantage of the data that is stored. There are two different cloud infrastructures within their infrastructure: service cloud and vendor hosting. Service cloud is used to support the customers and while their customers are operating the vehicles. This will enhance the car from the information that is gained based on the design and performance level of the car. Vendor hosting is used for the data that is located in separate warehouses.

Over the last decade, computer and telecommunications technologies have developed at a surprising rate. Increased computing power, advances in data transmission, smart and user-friendly graphic interfaces present law enforcement agencies with unprecedented capacity to collect, store, analyze and share data with stakeholders inside and outside of government. Ultimately, information technology represents a tool to help local law enforcement achieve its broadened and increasingly complex missions. (Reichert, 2001) There are many advantages associated with using information technology in policing. Comparative analysis shows that using information technology (IT) to combat crime has save lot of resources and time in the police department. There are a number of other advantages that can be associated with the use of information technology in the police department. For instance they use of Automated Field Reporting System by the police department has eradicated the use of hand writing of reports at the field by the Police Officers. Officers completed handwritten incident reports in the field and submitted them at the end of a shift to a field supervisor. After reviewing and approving reports, field supervisors would...

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......

...Information Technology continues to improve over time. In today’s society, with the help of technology, mobile phones have the capability of acting like a computer and so forth. So with the creation of the program COMPSTAT, there was numerous years of data that was added into the database with new daily information added to predict which areas would have the highest rate of crime based on what has happened in the past (Goode, 2011). Before COMPSTAT, the officers would patrol spots that they thought might be a high area of crime based on their experience in the field (Goode, 2011). This allows the police officers to be able to target the crimes when they are taking place to prevent them from occurring based on the presence of the police officers. This also allows for officers to catch people in the act to be arrested and possibly file more charges against the criminal. This advantage allows for time to be used more wisely to go off of the data that is known for trouble spots to keep the crime down in those areas. The disadvantage of the program would be that if there was not any crime occurring in the area that the officers were sent to that it would be the same as patrolling as they would be wasting time until they were dispatched to take care of something else. With the patrolling of the streets, it more likely that the officers are waiting for a crime to take place and then they pull someone over . With COMPSTAT, it is more like a stakeout where they wait until the......

Assignment 4: Data Mining Webopedia (2013) defines data mining as, "A class of database applications that look for hidden patterns in a group of data that can be used to predict future behavior. For example, data mining software can help retail companies find customers with common interests." This means that large groups of data that is derived by information obtained through customers, customer purchases and customer buying habits. Businesses use this information for a variety of reasons; it is used for purchasing merchandise, tracking how certain merchandise is selling and even customers buying habits. Webopedia goes on to state that "data mining is popular in the science and mathematical fields but also is utilized increasingly by marketers trying to distill useful consumer data from Web sites." Predictive analytics are used to understand customer's behaviors, according to the article Predictive Analytics with Data Mining: How It Works (Siegel, Feb. 2005) it describes how this method has a predictor.

Cis 500 - Predictive Policing

...Predictive Policing By Gus Finklestein Strayer University Abstract Predictive policing is a relatively new crime-fighting technique that can be used to both deter crime and catch criminals red-handed. Combining computer technology together with area- specific crime data, reports are generated forecasting precisely when and where crimes are most likely to occur. Police departments maintain records, data, and or databases which log huge volumes of information on crimes, criminals, suspects, and much more. Inputting that information into a sophisticated computer program designed to predict crime, to within a 500 by 500 foot location, is proving to have some merit. With technological advances, police no longer radio headquarters to retrieve basic information like license plates. In fact, the majority of police possess internet-connected computers in their cruisers, allowing them access to vast amounts of data. Within an organizational context, when police easily communicate and share knowledge across boundaries, and the entire country, the overall efficiency of crime-fighting and crime- solving greatly improves. Take for example an Amber Alert, the name of a missing persons report when a child vanishes. Once an alert is executed, police forces very quickly mobilize and cast a very wide net using all available resources to locate that child. This paper discusses the uses of technology, in particular predictive policing, to advance the......

Open communication and trust was barricaded and destroyed by ASK (financial IS). The workers were being motivated by fear, much like Geneen in Morgan’s Images Of Organization. From an IT architecture standpoint, numbers based on the finance division depicted the entire company, even the organizational structure. The organizational structure did not align with the IT architecture, and the culture did not align with it either. Morgan stated, “The division of labor characteristic of industrial societies creates a problem of integration, or what may be more accurately described as a problem of integration, or what may be more accurately described as a problem of “cultural management.”” Compaq started as a functional structure, changed into a divisional fairly soon and then back to functional. Culture was strongly emphasized over anything else. CASH stated, “The process encompassed a whole range of ideas, including (1) the rule of inclusion, (2) teamwork, (3) “working the issue,” and (4) consensus building.” The IS system at Compaq did allow the free-flow of information through email named “B-mail.” ASK was used for financial services so that the company could easily track orders, and know where it stood financially.
