4G Wireless Networks Essay Example | Topics and Well Written Essays - 1000 words

4G Wireless Networks - Essay Example Two major cellular service providers of USA, AT&T and Verizon will be addressed specifically for case study purpose. Comparison and Contrast between 3G and 4G Objective of this section is to compare and contrast 3G and 4G communication with respect to four specific areas, e.g., service and application, network architecture, data throughput and user perceptions. 3G providers are currently offering services like Code Division Multiple Access, CDMA, Universal Mobile Telecommunications Systems (UMTS), and Global System for Mobile Communication (GSM). On the contrary, 3rd Generation Partnership Project (3GPP) developed the 3GPP Long-Term Evolution (LTE) standard for 4G services which is commonly known as 4G LTE(Kuran & Tugcu, 2007). From application perspective, 3G provided the users the luxury of multimedia streaming. 4G added more amenities on top of that, including high definition (HD) services for audio-video conference, and online television via smart phone. Such differences in ser vice and applicability are primarily emanated from the network architecture of these two technologies, also from associated upload and download speed. 3G network is based on wide area cell; on the other hand, 4G integrated Local Area Network (LAN) with such wide area architecture. Consequently, data throughput rate for these two technologies also varies significantly. While 3G is offering up to 3.1 mbps with a bandwidth of 5 – 20MHz; data throughput rate for 4G networks is 3 to 5 mbps but potentially estimated at a range of 100 to 300 mbps with a bandwidth of 100MHz (Kuran & Tugcu, 2007) . Whatever the services and other application are, the most important aspect of any wireless service provider is the user feedback. As of yet, 3G wireless network has a broader coverage than 4G network. Therefore, 3G network enjoys the benefit of being readily available to the user. People are happy with 3G performance because it is the upgrade of 2G technology. The users accustomed to the slower connectivity of 2G, are certainly happy with this upgraded version. In this era of technological advancement, until user gets the flavor of new upgrade, he/she always compare the available technology with previous alternative that is why new technology always prevails. Yet now, in case of audio listening or video streaming, 3G did not receive too many complains and these users will not feel the differences between 3G and 4G that much. However, with time and increasing 4G coverage, things may change radically. Differences between Different 4G Communication Varieties As 3G and 4G are different in many ways, there are also distinguishable differences among different types of 4G network services e.g., 4G LTE, 4G WiMax, and 4G WiBro. 4G LTE is the oldest version of 4G wireless which offers 100 Mbps for downloads and 50 Mbps for uploads in ideal scenario(Evans & Baughan, 2000). However, in USA maximum speed provided by 4G LTE is 18.6 Mbps for download and 9.0 Mbps for upload by A T&T. Fixed WiMax, stands for Worldwide Interoperability for Microwave Access, can provide speeds of up to 75 Mbps and Mobile WiMax offering speeds of up to 30 Mbps (Fu et al., 2010). Although, service provider sprint in USA showed download speeds of 3-6 Mbps and upload speeds of 1 Mbps (Sprint, 2013). Wireless Broadband, Wibro, provided by

Exploring the Logic of Experimental Design Assignment

Exploring the Logic of Experimental Design - Assignment Example Experiments are conducted by carrying out research studies, which attempt to put together information that is pertinent to the aims of the experiment. According to Jackson, the accomplishment of an experiment’s purpose is determined by its design and the way it is executed. Formal experiments evaluate physical entities while other modes of experimentation involve carrying out studies that involve observation and statistical surveys. The design of an experiment determines the feasibility of the intended results to the subject of the experiment, which makes experimental design a crucial factor in all analytical work (Scott, 2010). This paper seeks to highlight and explore the logic of experimental design, and how to apply them to create designs used in analytical research. Question #2 Experimental design is closely associated with methodology which are the steps taken to accomplish the task set out by the experimental design. An experiment is an inquiry into the intrinsic featur es of a subject, and it this inquiry requires a predetermined process of execution for it to serve its purpose (Jackson, 2012).The development or creation of an experiment stems from lack of information pertaining to the nature, function or purpose of an entity. Thus, this uncertainty and lack of knowledge prompts activities that are geared towards establishing and information concerning the unknown. Methodologies are ways of carrying out these activities, and they give rise to experimental designs that ensure these activities are purposely oriented. All endeavors that are carried out by man in an effort to gather information about a subject can be considered experiments or studies. This is because the sole purpose of an experiment is to account for or discount the nature and existence of a phenomenon. An experimental design accomplishes its purpose by ensuring that the methodology adhered to in an experiment is geared and oriented towards garnering the appropriate results in accord ance to the research hypothesis. Research hypotheses are the questions that experiments seek to answer by confirming their assumptions or disapproving their postulates. Question #3 The major advantage of experimental designs is that when they are properly conducted, they have the ability to illustrate causality. This is achieved by the degree to which the experiment’s parameters manipulate exposure to independent variables and elimination of confounding variables. For a study to qualify as a true experiment, the methodology should be designed in such a way as to exclude dependent variables (Scott, 2010). This is an aspect of experimental design that can be applied in educational studies to determine the cause and effect of both external and internal factors in an educational system. A disadvantage associated with experimental designs in an educational study is that they are difficult to design because they require a lot of human energy and resources. To effectively design an experiment focused on an educational system, it requires taking the behavior of the concerned parties, and in this case students, into the context of the experiment. This raises some hard to answer questions based on the ethical and moral consideration of the experimental group (Trochim, 2008). Question #4 Experiments are conducted using independent and dependent variabl

Knowledge and skills for nursing part 2 assessment Essay

Knowledge and skills for nursing part 2 assessment - Essay Example Based on the background check patient had suffered severe depression because her husband died and live alone. The patient became alcoholic and her health deteriorated because of malnutrition. The patient looks underweight but can survive by giving proper medication and patient care. The nursing process can best be described as a framework for planning individualized care for patient with intellectual disabilities. Since the care for patient is a process it does not conclude into anything but rather it changes constantly and it is the nurses' responsibility to respond to these changing needs whenever necessary. The nursing process usually comprises four or five stages depending on the resources available and work setting, and includes: diagnosis, assessment, planning, implementing and evaluation. The nursing process should be undertaken using a collaborative and participative approach with other professionals, gathering and implementing resources, in order to improve the care process (Department of Health 2000b; Department of Health 2001). The focus of this study will be on the design care plan for our patient on study. The patient was brought in the hospital because of diarrhoea and vomiting. ... It includes areas such as health and health needs, daily living skills, activity programmes, mobility, mental health, risks to the client, finance, respite, social events/outings, support requirements, spiritual needs and, possibly, accommodation issues (Department of Health, 2000b;Sox, 2004a). Our patient on study has been diagnosed to have severe diarrhoea, but upon assessment the medical team handling the patient found out deeper reason for having such condition. The patient based on its medical background is having depression due to the lost of a husband. This has made the patient to neglect herself and become alcoholic.

The chosen model should cover the entire activity of the patient. Planning In planning, the nurse plays an important role in the recovery and stay of the patient in the hospital. The patient upon admission was given attention on the main complain which is diarrhoea and vomiting. However further diagnosis and assessment of the medical team discovered that the patient is suffering from malnutrition. Our plan focus on malnutrition; the reasons why the patient is having this kind of condition, and the treatment and the protocol that the nurses should follow for the welfare of the patient. Implementation Implementation of a care plan is the most challenging part of the nursing process. Patient who is suffering from depression will lead to intellectual disabilities and an appropriate care plan should be implemented. In the case of our patient, she suffers depression after her husband dies wherein she depends on a lot. This make her

D3.1 The Wet Foot Dry Foot Policy Essay Example | Topics and Well Written Essays - 250 words

D3.1 The Wet Foot Dry Foot Policy - Essay Example Any illegal immigrant from Cuba, whether traveling by sea or by land, and has now managed to reach American soil, should be granted asylum, because these people are fleeing from a one-man rule communist dictatorship. There should be no distinction whatsoever, as it betrays Americas democratic principles, the very political foundation of the country as it was envisioned by the Founding Fathers. Perhaps a more sensible approach is to exclude Cubans who went to the United States of America purely for economic reasons, since they would not qualify for political asylum to be given temporary green cards. In the absence of any evidence to the contrary, all Cuban immigrants should be given the benefit of the doubt (Iraola para. 4). The legal distinction contained in the current policy is merely hair splitting and does not serve any purpose at all; it is better to grant every Cuban immigrant permanent residency status and the rare chance to live in freedom. These people had gambled everything, even life and limbs, to reach the United States and it is heartbreaking to turn them back, based on moral and ethical human rights consideration. It is cruel and inhumane to turn them back; it is like bringing an escaped slave back to his master (McGill para. 13). This policy should be

Thoreau Essay Example | Topics and Well Written Essays - 500 words

Thoreau - Essay Example Thoreau questions the power of majority stating that the decision of majority does not necessarily ensure superior wit or justice. In the same way, it will be a fallacy if any one thinks that individual choices are inferior to the decision of majority. Regardless of the utmost virtue, governmental decisions are often subjected to the interest of majority groups. Thoreau was influenced by the social conditions in which slavery had been the major characteristic. Yet his convictions are of great relevance today as the modern democracies like the United States, UK, and India have been testing this ‘game of right and wrong’ (voting) for decades. The political settlements in these multicultural nations have become a sort of ‘betting’ as Thoreau envisaged because representation is the inevitable, perhaps the sole strategy for minority groups to negotiate their privileges with majority. It is believed that democratic representation will help control the majority by promoting a win-win atmosphere. Moreover, important decisions could only be taken after detailed discussion and debate. Minority groups are given chances to achieve their goals and to limit the interests of other groups as well. In contrast, though minority groups and other weaker sections are given constitutional backup for proportional representation in legislation, justice has always been left to the choice of majority. Thoreau suggests that people should not allow government to weaken their conscience. He also states that if any one hold back one’s conscience in favor of law, the person is badly serving the state. Moreover, the power of majority might curtail the freedom and rights of other communities. Therefore, he believes that a wise man can not leave the right to the mercy of chances. Leaving the justice to the choice of majority is highly irresponsible act that can bring ultimate

Scope of branding and current trends Essay Example | Topics and Well Written Essays - 2000 words

Scope of branding and current trends - Essay Example Interestingly brands in the field of marketing originated in the 19th century with the advent of packaged goods. Industrialization moved the production of many household items, such as soap, from local communities to centralized factories. These factories, generating mass-produced goods, needed to sell their products to a wider market, to a customer base familiar only with local goods. So the packaged goods manufacturers needed to convince the market that the public could place just as much trust in the non-local product. Around 1900, James Walter Thompson published a house ad explaining trademark advertising. This was an early commercial explanation of what we now know as branding. Since their origin, brands have come a long way in technique, sophistication and reach. Many traditional â€Å"rules† of branding have been tossed aside over the years with the advent of the internet, cutting edge branding techniques and complex ventures. Branding has also conquered new terrains su ch as law firms, countries or even local produce. In this paper, we will attempt to identify and expand on some of the latest trends in branding and their scope. We will also attempt to demonstrate how these changes in branding concepts are a reflection of our times and a natural progressive reaction to external factors that has driven its rapid and powerful evolution. But, before we delve into that, we first take a look at the various issues that influence responsible branding to really comprehend the magnitude of a strong brand influence and also its constraints.
