...(1G) Vodafone analog phone which launched in 1985() to what is now known as the smart phones (3G and above). After the creation of the cellular devices, people who owned these devices were considered to be one of wealth. In today society, the cell phone has become a new toy. Today’s cell phone, it is what one would consider a hand held computer. These cellular devices can store data, send data, have virtual conference calls and other amenities like never before. With the creation of the 3G, 4G and the 4G, LTE, the speed, space and performance of the cellular devices has become the marketing tool for devices. In 2001, the 3rd generational Partnership Project (3G) network was introduced in Japan by NTT DOCOMO under the brand name of FOMA (freedom of Multimedia Access). The 3G network that is known today by Verizon customers is one of which that has been adopted globally. The CDMA2000 EV-DO is the latest version of the 3G network. The creation of the 3G network has created a multifaceted avenue upon which uploads, downloads are faster than the ordinary computer. A report created by Qualcomm stated that, “Handheld mobile Internet access is very popular in emerging markets because handsets are much more prevalent than PC (Qualcomm 2009)”. People are now able to access the internet and its contents by the touch of a button on their cellphone as compared to finding a lap top or desk top. 3G devices can be used on the go while in a vehicle, at work, or on public transportation.

...phone service across the United States with a wide selection of different phones. Today smartphones seem to be the most widely used by the American population. The smartphones of today are like mini hand held computers, possessing the capability to perform many different functions. When it comes to cell phones there are two major networks available, 3G and 4G. The "G" stands for a generation of mobile technology, installed in phones and on cellular networks. 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).(Segan, 2013) Third-generation mobile networks, or 3G, came to the U.S. in 2003. With minimum consistent Internet speeds of 144Kbps, 3G was supposed to bring "mobile broadband." There are now so many varieties of 3G that a 3G connection can get you Internet speeds anywhere from 400Kbps to more than ten times that. (Segan, 2013) While most of us are used to getting high speed Internet connections at home, the office or even the local coffee shop, once we are on the road those high speeds have to stay behind. With 4G the promise is that you can get real mobile broadband to go. (Vilches, 2010) There are two fundamental aspects of LTE. The first is that the technology finally leaves behind the circuit switched network of its GSM roots and moves to an all-IP flat networking architecture. This is a significant shift which in very simple terms means that LTE will treat...

...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...

...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...

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...

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...
