...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...

...4G Wireless Networks Walter Clay Strayer University Abstract Today many of the wireless telephone companies from Verizon to AT&T to Sprint tries to persuade consumers that their networks are better than the other companies. 3G technologies ushered in the era of smart-phones and they have been the driving factor of many of the advances in wireless technologies today. As smart-phones and wireless technologies improve technologically savvy consumers are demanding more and more from wireless companies. Today, there are two wireless standards; 3G and 4G. 4G Wireless Networks When you look at 3G and 4G wireless networks you can compare and contrast them in four areas: service and application, network architecture, data throughput and user perceptions. “Compare and contrast 3G wireless networks to 4G networks in terms of services and applications” Applications are the primary reason consumers use smart-phones today. They get hooked on the convenience the applications bring to their lives. 3G is the first wireless network to provide these capabilities for consumers. For the first time they were able to have a video call with a family member on the go, they were able to stream movies and video, and even able to video conference on the go with the office. 4G picked up where 3G left off, it provided the capability to access information at the same speeds that you could on your computer at home. Consumers are now playing video games on the go, watching live sports events...

...4G Fourth-Generation Cellular Communication System AGENDA y y y y y Introduction Evolution of Data Standards WiMAX The Road Ahead Closing Thoughts 4G DEFINITION 4G 3G 2G 1G 0G Fourth Generation Cellular Communication (4G) 4G is not one defined technology or standard, but rather a collection of technologies and protocols aimed at creating fully packet-switched networks optimized for data. 4G networks are projected to provide speeds of 100 Mbps while moving and 1 Gbps while stationary. EVOLUTION OF DATA STANDARDS 4G 3G 2G 1G 0G Zero Generation Mobile Systems (0G) The radio telephone system preceded modern cellular mobile telephony technology (1G). The radio telephone system contained one central antenna tower per region. The central antenna required radio phones to have a powerful transmitter, capable of transmitting up to 50 miles. The number of radio telephones per region was limited by the number of available channels. Unlike closed radio systems, radio telephones were connected to the public telephone network and were typically mounted in cars, trucks, and briefcases. EVOLUTION OF DATA STANDARDS 4G 3G 2G 1G 0G First Generation Cellular Communication (1G) The 1G cellular telephone system divided cities into small cells. This division allowed extensive frequency reuse across a city, allowing millions to use cell phones simultaneously. 1G cell phone technology encompassed analog standards introduced in the 1980s and continued...

With changing technology, almost everybody has a smart phone which enables them to check their emails or surf the web. Currently, there are two different wireless networks: 3G and 4G. 3G or 3rd generation mobile telecommunication is pretty much an application service that includes wide-area wireless voice telephone, mobile internet access, video calls, and mobile TV, all in a mobile environment. 4G is pretty much the same concept as 3G except it’s ten times faster than 3G. (Lee, 2011). Smartphone users are now consuming more data than ever before on a per-user basis (Kellogg, 2011). With the availability of new apps, services, and cloud storage, users are now utilizing their internet connection more than before (Nguyen, 2012). The current architecture of the 3G network starts with a base station what is referred as a Node B. The radio network controller (RNC) will provide various types of radio-related functionality such as: resource allocation, link layer encryption, and paging and fine-grained location tracking for mobiles in idle mode. It will also provide mobility anchoring for mobiles` data flow as they move from node to node. Meaning...

...3G vs. 4G Wireless - What is the difference? First off, the "G" stands for a generation of mobile technology. Each "G" generally requires you to get a new phone, and for networks to make expensive upgrades. The first two were analog cell phones (1G) and digital phones (2G). Then it got complicated. Third-generation mobile networks, or 3G, came to the U.S. in 2003. With minimum consistent Internet speeds of 144Kbps, they were considered mobile broadband. There are now so many varieties of 3G, though, that a 3G connection can get you Internet speeds anywhere from 400Kbps to more than ten times that. New generations usually bring new base technologies, more network capacity for more data per user, and the potential for better voice quality, too. 4G phones are supposed to be even faster, but that's not always the case. There are so many technologies called "4G," and so many ways to implement them, that the term is almost meaningless. The International Telecommunications Union (ITU) tried to issue requirements to call a network 4G but they were ignored by carriers, and eventually the ITU gave up. 4G technologies include HSPA+ 21/42 (HSPA was for 3.5G), WiMAX, and LTE (although some consider LTE the only true 4G of that bunch, and some people say none of them are fast enough to qualify.) There's one thing for sure though, each generation offers faster Internet speeds than the last, on the same carrier. Sprint's WiMAX 4G is almost always faster than its CDMA 3G. But AT&T's...

...Technology has shaped the world into what it is today. We have gone from plugging mobile phones into the car, to wireless service over the years. As consumers become more demanding in what they want and need in a wireless network, the more technology evolves through faster service, connectivity, and mobility. 3G and 4G networks are the technology of today, but tomorrow will yield another network much better. 3G and 4G are similar but different when taking the services and applications, their architecture, data throughput, and users perceptions of these networks into consideration when choosing the right network. 3G is the 3rd generation of cellular telecommunications technology that offers broadband services in CDMA, EDGE, EV-DO, and HSDPA, while 4G offers LTE, WiBro, and WiMax (Turbin, 2011. Table 4.1. pg. 97). The Applications a network offers, brings the consumers closer choosing the right network. 3G allows streaming and listening to music, watching movies, playing games, taking better pictures, and video calling. 4G offers the same applications as 3G with additions of its own; Hi Def TV through the cellular service and multiplayer capable games, and downloading social media. The architecture of 3G lies within its Wide Area Cell based circuit switched system, providing voice and data. This means when a user makes a call, its signal is transmitted through a dedicated circuit that can only be used by that call until the session has ended (Turbin, 2011. pg. 94-95.)...

...4G Wireless Networks Elizabeth McDowell Strayer University CIS 500, Summer Semester Professor Robert Culver August 20, 2012 (for week 4) 4G Wireless Networks Standards for communication have come a long way in the world of mobile devices. It starts as early as the 1980’s with the 1G, or first generation, that was a totally analog service (Brown, 2012). The nineties stepped up technology with the 2G, or second generation, network and this service was fully digital and the beginnings of wireless data being supported by mobile devices (Brown, 2012). The two most current used services are 3G (3rd generation) and 4G (4th generation). 3G was introduced in the 2000’s and offered faster service than the 2G did previously. It offers data throughput of up to 3.1 mbps, with a peak upload rate of 50 Mbit/s and a peak download rate of 100 Mbit/s (NA, 2012). It uses packet switching and a Wide Area cell Based network (NA, 2012). Although, truly, there is no clear definition of what data rate a user can expect with 3G service (Segan, 2012). There is, however an increased transmission rate with the 3G service of 2 Mbit/s for someone who is stationary and 384 Kbit/s in a moving vehicle (Goodman, 2005). Current services that can be offered on a 3G network are mobile TV, video conferencing, telemedicine, location based services and GPS. This was the first service that allowed for streaming of audio, video and video calling (NA, 2012)...

...4G Wireless Network | Compare and Contrast 3G Wireless Networks to 4G Networks 3G networks allow people to have high speed access to data and voice services, they are essentially a high-speed mobile Internet, that can offer speeds of up to 3.1 megabits per second (Mbps) or more. This speed is around the same speeds offered by earlier sellers of cable modems. However, depending on where you are and how many users there are, the actual speed of 3G networks will fluctuate. Even though 3G is still more commonly used, the recently introduced 4G networks have quickly become the standard for wireless communication. The 4G networks are 4-10 times faster than 3G protocols and are ideal for watching streaming videos or movies, and offer more security, unlike a Wi-Fi connection. We can compare and contrast 3G wireless networks and 4G networks in four areas: service and application, network architecture, data throughput and user perceptions. The following standards are typically branded 3G: CDMA2000, UMTS, and EDGE. Whereas 4G wireless is the term used to describe the fourth-generation of wireless service such as WiMax and LTE. Although 4G is a step up from 3G, the limited coverage that is the present 4G market keeps 3G as the frontrunner in wireless protocols being used by the public. While all 4G service is called "4G," the underlying technology is different. Sprint, for example, uses WiMax technology for its 4G network, while Verizon Wireless uses a technology called Long Term...
