The innovations of communication technology in
Question: Trace how technology has changed communication in your country over the past 20 years.
With the development of technology, the changes in communication have a pivotal impact on various areas. Definitely, advanced technology is the main driver of these changes. Not only the way of communication has changed, but also the content and means of communication have evolved. The aim of this essay is to examine the evolution of communication technology in China and evaluate its impact on individuals and society.
Before 1990s, the main technology applied in communication was called 1G, or the first-generation of wireless telephone technology (Rathod 2012). It transferred only voice data without being encrypted. The sound quality and the speed of transfer were in poor conditions as well. However, over the last 20 years, the quality of communication in China has increased significantly with the development of 2G, 3G and 4G communication technologies.
In 1990s, the 2G technology was introduced. This abbreviation refers to digital voice systems, i.e. systems that transmit information via voice signals, which replaced early analog phones. 2G may be considered a revolutionary technology as it not only improved communication, but also contributed positively to public health. In terms of communication, 2G devices secured privacy, which means the data will be encrypted before transferring. What is more, this digital technology allowed designing radio-free mobile devices which are less harmful for human health. However, the main advantage of this technology – the use of digital signals – is also its major limitation; in other words, if the digital signals is weak, it cannot reach a cell tower and, therefore, people who live in distant areas cannot use 2G to a full extent. Eventually, the need for a more reliable...
