The innovations of communication technology in
China

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 communication technology had become obvious, and here came the 3G communication technology.

As UMTS (Universal Mobile Telecommunications System) Forum (2005) claimed, 3G was first available in 2001 in Japan and it was not introduced to China until 2009. This technology enables using various services with higher speed and stability, such as GPS, digital television and visual conferencing. In addition to convenience and functionality, 3G services are extensive available, which means people may be connected with each other by communication networks with less limitations. This advantage is especially visible in China: according to statistics, China have total of 56.71 million 3G users in 2012 (Cellular News 2012). However, subscribers must pay for 3G mobile handsets, which are more expensive than 2G devices. Additionally, 3G handsets are more power-consuming. That is to say, with the same power condition, 3G devices work few hours than 2G models.

Meanwhile, with the wide use of 3G technologies in China, the implementation of 4G technology is on its way and is expected to be widespread before 2015. 4G is an advanced step up from 3G, which represents the highest achievement in communication technology. 4G users are provided with a comprehensive mobile broadband solution to mobile devices like laptops and smartphones, which enables higher speed of data transferring. However, the availability of 4G is limited for its implementation. Due to the unstability of new technology, 4G technologies are only used in urban area. But there is no doubt that these barriers must be overcome with the promotion of technology.

In conclusion, great changes in communication technology have taken place in China over the past 20 years, being innovated at an amazing rate. Thanks to technology, Chinese people now are able to connect with each other quickly and easily, which seems to be impossible in the past. Even though further development of technology is still hindered by a number of factors, it has changed our life for the better. In the future, the communication technology in China is sure to move on steadily.

Technology Transfer to China Final

...Technology Transfer to China: Guidance for Businesses Technology Transfer to China - Why Worry? Many European companies are keen to come to China. While in the past, European companies came to China to take advantage of low-cost manufacturing for export, more recently, they have come to enter the Chinese domestic market, establish R&D, engage in cooperative development, take advantage of a skilled work force, establish suppliers, and develop long-term partnerships in China. In order to achieve this, they are often willing to ‘transfer’ their key technology and designs to Chinese subsidiaries of European firms, joint-venture (JV) partners, or Chinese manufacturing and service companies. One of the challenges facing European companies coming to China is devising creative solutions to minimize the risk to their intellectual property (IP) associated with such technology transfers. A technology transfer happens in a number of different ways. European companies most commonly transfer their technology by licensing their patents, designs, software, trade secrets, and know-how. Ownership of the technology may be transferred, but this type of transfer is less common. A common misconception is that a technology transfer is limited to transfers of high technology. However, many European companies using contract manufacturing to manufacture low technology, consumer, or industrial products, for example based on product designs, must deal with many of the same risks to their IP as their......

Provide your analysis with justifications. Question 2: Discuss the main sources of innovation, and what are particularly important for a company such as Skullcandy and why? MGT3130 Innovation and Technology Management – CP2 Question 1 Skull candy team structure can be characterised as hybrid lightweight and heavyweight. On the basis of it being lightweight the skull candy team members would still reside in their functional departments (Melissa A. Schilling 2010). The light weight teams at Skull candy have a very clear functional affiliation and would only work on the project that is given part time. The location of the team members of the Skull candy will always be in their functions thus allowing them to easily work together. Therefore the team members conduct the projects in their own departments (V. Patrick et all 2007). The functional departments will always have the responsibility of the work being done in that department. The skull candy case shows that there is close contact between the team members and also the functional managers and the project manager. Skull candy light weight team structure is......

Technology Communications

...Technology Communications in Businesses Hello everyone my name is... and I wanted to share with you some of my knowledge of technology particularly information processing and content handling functions and the tools that make it all possible today. Technology Communications in corporations and businesses has evolved over the years and taken a more unified role because of the integration of telecommunications as in telephone lines and wireless signals, computers, audio-visual systems, enterprise software and storage which enable users to access, store, transmit and manipulate information. There are several technology equipments today that make this convergence of telephone networks and computer networks possible. They are making accumulated knowledge accessible sharable and searchable so the right people can see the right information at the right time and add their expertise which means more collaboration, innovations and success. The Cisco IP phones for example, capable of providing high quality, consistent communications for business needs. They transmit voice communications over the network using open standards based internet protocol and extend communications services to all employees in the workplace within the network. Routers on the other hand connect businesses to the outside world while providing highly secure virtual private network access for remote employees mainly by forwarding of IP packets which are a formatted unit of data.

Innovation Technology

...Italy, as well as in the whole of Europe, has reached the maturity phase. The companies that are working within this industry are trying to capture fragmented profits through low cost and differentiation strategies1. Consequently, the threat of decreasing margins is a possibility. Additionally, globalization and the financial crisis have worsened the situation creating uncertainties and fears among producers. Globalization has decreased trade barriers and increased competition. In particular, Article 28 and 29 of the European Union Treaty (1993) supports free movement of goods and prohibits import and export restrictions within the Member States. Moreover, in May 2011, the antidumping laws applied to leather shoes coming from Vietnam and China has terminated. One of the typical phenomena of mature markets, the shakeout, has been strong and the number of firms within the footwear sector has decreased. Appendix 1.1.A shows that the birth rate of European manufacturing firms is inferior to the death rate, and the spread is higher than in other sectors. Many firms left the market not only because of its saturation, but also because they have not been able to match the cost advantage of international competitors. The economic and financial crisis has been particularly strong in Italy, which is experiencing a recession2. The new Prime Minister Mario Monti has started a series of strict policies in order to decrease the debt and increase internal competition. However, the new......

... 1.0 Introduction According to Leslie and Philip (2012), innovation is the commercial exploitation of new knowledge, in other words, developing new ideas into products and production processes and selling them on to customers. Innovation is also the process of translating an idea or invention into a good or service that creates value or for which customers will pay. The term innovation can be defined as something that are original and, as consequence, new that ‘breaks into’ the market. Innovation is needed for businesses to produce new products. Multinational Companies (MNC) can be defined as corporations which have their home in one country but operate and live under the laws and customs of other countries as well according to Ruth and Michael (2000). Generally, any company or group that derives a quarter of its revenue from operations outside of its home country is considered multinational companies. It can also be referred to as an international corporation. One of the examples of MNC is Starbucks. Starbucks Corporation is an American global coffee company and coffeehouse chain based in Seattle, Washington. Starbucks is the largest coffeehouse company in the world, with 20891 stores in 64 countries (Wikipedia, 2013). According to Leslie and Philip (2012), the global business environment can be defined as the environment in different sovereign countries, with factors exogenous to the home environment of the organization, influencing decision making on......

The good news for the governments and manufacturers backing a driverless car revolution, however, is that 46% of us would appear to have no qualms about being driven around by a computer. With testing due to start this year in Bristol, Coventry, Greenwich and Milton Keynes, it’s now vital for the UK government to win over opponents and “don’t knows” alike. These cars are intelligent transport mix is important element of a smart city and that is what the government is aiming to build. These cars will be able to access targeted, fast and efficient transport systems as well as will have the biggest impact on the wellbeing of the citizens and economic growth. One of the major effects of driverless cars is that a reduction will be seen in car ownership. Mostly cars will be used for specific journey types and shall be hired for short periods. Another change would be fuel consumption will be reduced along with carbon and particular emissions. The other benefits include increasing mobility and safety of the elders, blind and disabled. There’s also the potential for stress reduction and the eradication of road rage. Driverless cars could be a huge force for good, but buying into the concept is a huge leap for many.......

...Communication and Technology Carlos LR CJA 304 September 9, 2013 Michael O'C   Communication and Technology Specialized databases in the criminal justice system According to "History of Fingerprints" (n.d.), in 1901, Sir Edward Henry, an Inspector General of Police in Bengal, India, develops the first system of classifying fingerprints. This system of classifying fingerprints was first adopted as the official system in England, and eventually spread throughout the world. Since then there has been an enormous leap forward on the process used for identifying a person through finger prints. The process went from a lengthy detail examination of a finger print under a magnifying glass; to taking a person finger prints through a Live Scan machine and waiting for the results to return in the matter of seconds. It was not until 1905 that the United States Armed Forces adopted the finger print as a valid form of identification. It was subsequently use by police agencies. By 1980, the first computer database of fingerprints was developed in the United States. It was known as the Automated Fingerprint Identification System, (AFIS). In the present day, there are nearly 70 million cards, or nearly 700 million individual fingerprints entered in AFIS (AFIS. n.d.). Specialized Databases Firefighters, emergency medical services, and law enforcement personnel depend on receiving accurate and prompt information to perform their duties.

However, with the lack of knowledge that Walton did not have didn’t stop him one bit in building his dream company. Walton began building his company into a global leader of technology that it will soon become (Wail gum, T. 2007) Wal-Mart first opened the doors in 1962 in Roger Arkansas and that’s where Walton’s technology began to take off. The company officially incorporated as Wal-Mart Stores Inc. on October 31, 1969. By 1975, Walton had more than 125 stores and mass computers to control huge inventory and company information. Wal-Mart began putting registers in stores to better ensure the track of inventory for all of the companies that Walton owned. Now long after the store began using registers Walton came up with the ideal to use bar – codes on all products that are sold in Wal-Mart to follow the inventory and ensure that each product will be re-ordered as the products run low in the stores. By 1987 Wal-Mart had extended to the world’s largest private communication system in the United States (Wail gum, T., 2007). This communication linked all the Wal-Mart stores back to the central headquarters in Bentonville Arkansas to store all of the company information. Having this communication link in place it would ensure a better track of inventory and profits of all locations of Wal-Mart. Walton wanted to ensure that everyone......
