A 4G system is expected to provide a communication technology based on Internet Protocol. Internet protocol or IP is generally used in the computer networks for data communication among computers. All the devices are identified by a number called IP number. In 4G network this concept is extended to telephony with an intention to make data and voice communication integrated in the same architecture. The 4G network is supposed to facilitate a Gigabit speed i.e. a speed of 100+ Mega Bytes per second with a mobile node speed of up to 200km/hr. It will enable Internet access, IP…
Technological: In the past three decades, a major shift in technology has prevailed in the mobile handset industry. Through innovation and technological advances, the market shifted from analog transmissions (1G), to digital mobile communications in 1992 (also known as 2G), and ultimately to the Wideband Data Communications network (3G). With rapid changes in this dynamic marketplace only the most well-funded and well-managed companies have managed to emerge from generation to generation, whilst others have been unsuccessful.…
Mobile and fixed networks are now both extremely developed in today’s modern world. It is now completely possible to get blazing fast internet with wither a fixed line provider, or a mobile provider. The services provide more than internet though, also frequently providing phone and/or television services. These networks are far from perfect though.…
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. 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.…

- 802.11g: provides high speed wireless networking in the 2.4 GHz range. It will soon be replaced by 802.11n, so it too will be a legacy technology within a year or two. It provides three channels for indoor use in the United States. The 802.11g standards provides for more or fewer channels in other parts of the world whose radio frequency spectrum regulation is different. 802.11g was designed to take the best of both the 802.11a and 802.11b…
Since the introduction of the first mobile phone in 1924, there has been a steady climb in developing and enhancing, the mobile phone and its supporting technologies. The cellular network infrastructures as well as service providers have been hard at work; in making sure they are providing the best service as well as devices. The infrastructure alone has gone through several life cycles. Which is required in order providers to keep up with growth and technology changes. Wireless cellular providers, at one point offered services that ran off analog frequencies. Today the wireless networks are built off of an all-digital network, which is considered to be in its 3rd generation. 3rd generation technologies include GSM, GPRS, UMTS and CDMA.…
Although we as a people could not imagine life without our cell phones or laptops, fixed line networks were the standard up until cellular phones were introduced. “Fixed lines are in every home and building today so everyone has the ability to have a telephone and data service. To receive or transmit data over the fixed line a modem is needed on each end of the line. The modem takes the digital information and turns it into tones that have been specifically selected for the transmission over telephone network. The modem at the other end is responsible for turning the tones back into digital data. Data rates were limited until digital subscriber line (DSL) was introduced. DSL used the existing analog phone line so there was no need for new equipment other than modems that convert digital data into high-frequency tones along with a filter at the users end to keep DSL transmission from being heard on the telephone.”…
How much faster is 4G compared against 3G? The speed of 3G networks depends on how they are implemented. By 2010 Verizon (a CDMA network) had reached the limits of its 3G network speed in the United States. 4G networks allowed Verizon the ability to offer transmission speeds up to four times faster than its current 3G network. AT&T’s 3G network, however, is based on GSM. The GSM design left AT&T room to upgrade its current 3G speeds. “…it is anticipated that when AT&T upgrade[s] their 3G networks, their speeds will become comparable to 4G from…Verizon. (Diffen, 2011)”…
2g compared to a typical 3g speed is a huge difference. 2G transfers at 10 kbps and 3g can transfer at speeds between 300 and 500 kbps. This allows 3g to have web access as compared to 2g as well as high quality photos, and low quality video.…

The cellular phone industry has evolved over a period of 20 years, from first generation to third generation mobiles. The inventions by mobile industry incorporate:First Generation (1G) -The first generation mobile phone refers to the mobile phones that were developed in the 1980s. Second Generation (2G) -GSM, CDMA and TDMA are the different protocols that brought the mobile phone into the second generation stage. The 2G was introduced to the market basically in the early 1990s. Second And a Half Generation (2.5G) -Still under the same network protocol, but provided services such as WAP and GPRS enabling mobile phones to access on certain websites. Coloured screen with camera featured mobile phones were also introduced in this stage. Third Generation (3G) -A whole new network protocol launched in the twenty-first century. It is either under IMT-2000, UMTS or W-CDMA standards. The 3G protocol enables high speed connection (speed similar to broadband connection) to access through internet and also video calls.…
The 3G Wi-Fi network will provide the marketing advantage over the competitors by increasing the need to supply more connection opportunities for businesses, homes, recreational facilities, and airports. The objective is to provide connections to every organization and households, including netbooks and gaming systems within Canada and surrounding regions. “Connections to more than 200 countries will increase market needs with an added bonus of a built-in SIM card within the Wi-Fi network system” according to Lawson (2010).…
