4G Cellular Communication - Research Paper Example The technology provides high speed and quickens transmission of data from one place to another, hence making mode of communication be fast. However, the research will face some challenges in the coming years since it will require some conditions for it to run perfectly well. The objectives of the 4G cellular communication are aimed at improving the methods of communication within two groups of people as fast as possible to enhance economic growth of the world. The potential abuse of the technology occurs when individuals fail to follow the regulations provided by the technology. Introduction There always is the need for communication regardless of place and the distance. Consequently, there has been an augmented demand of wireless communication by companies globally owing to the awkwardness in using fixed wire telecommunications. The fourth Generation (4G) is a new technology seeking to address communication needs of the populace. The 4G of cellular communication are the advancements that are realized in the wireless telecommunication industries in the recent years globally. They provide fast transfer of data across electronic devices compared to the previous cellular communication approaches such as third generation (3G). The high speeds of the data transmissions upgrade the quality of communication through improvement of high definition video. According to Lu and Hu (2006), 4G is highly expected to transform the mobile communication system through upgrading smart phones to perform certain tasks that were only previously achievable by personal computers (PC). Mobile communication is going to be affected positively by the introduction of the fourth generation, since it will transform and improve its operation. In this essay, the development, challenges, uses, potential abuses by individuals, potential new developments, objectives, features, and application of the fourth generation technology are discussed broadly. Development Its history can be traced in the 19 70s when the first generation was introduced. It comprised of analog technology that was used to unravel essential problems that existed during that time. Analog systems were used to assist in communication in dissimilar places worldwide in the 1980s. However, the system was deliberate and unwieldy to use, but it was a successful discovery that initialized a technological journey. The second generation (2G) was introduced in 1980, and was used for voice applications and introduction of digital techniques that improved the speed of data transformations (Brand & Aghvami, 2002). The technology launched the use of circuit-switched data communication that enhanced use of the digital communication rather than the analog system. 2G is still used worldwide by few people since the technology involves some digital aspects, which are habitually preferable. The introduction of 3G was highly appreciated for the substantial improvements it launched in the communication expertise. The implication of 3G was that it improved the voice technology in channels (Arshad & Farooq & Shah, 2010). However, it faced a challenge since the two companies that instigated the technology failed to agree on the terms and parted ways. The 3G telecoms business has been outstandingly successful and has gained many profits in the few years since its launch. The technology has influenced the mobile technology that has subsequently assisted in the overture of internet in

Teacher Satisfaction and Student Academic Achievement Essay

Teacher Satisfaction and Student Academic Achievement - Essay Example It is a mixed study that was conducted to gain a better understanding of the beliefs and attitudes of teachers concerning job satisfaction from the viewpoint of small school district teachers. It is a study that attempts to understand more clearly the factors and reciprocal influences that affect teacher job satisfaction, particularly in the context of the operation of small schools, faculty stability, homegrown and transplanted teachers, teacher quality, and the relationship between teacher job satisfaction and student achievement. There is general consensus that small district schools exist in a unique environment as compared to the balance of other types of schools in public education (Anschutz, 1987, Arnold, 2005, Belsie, 2003). Small district schools operate working under the same laws and with comparable expectations and goals as their urban and suburban counterparts, but absent of the same quantity or quality of support and resources available from the school's central organization or the local community. Ultimately, it remains a school district's responsibility to provide a quality and appropriate education to the youth of their community. To accomplish this, teachers are the main vehicles that set the climate, offer encouragement, and deliver the curricula that students require, in pursuit of successfully meeting the expectations set by state and federal legislation, as well as the local administration, regardless of the functioning condition of the district. Consistently, the most valuable and accessible resources located within a school district are the teaching staff. Despite having teachers as an easily available resource, schools often do not include teachers as a resource at the levels desired or expected by
