4G Wireless Networks: Data and Bandwidth Improvements 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

A 4G primer WhAt is 4G? 4G stands for fourth generation‚ the wireless technology standard that’s considered the successor to the 3G‚ or third-generation‚ high-speed‚ mobile telecom standard. The key difference is that it’s designed for wireless or mobile data services using spectrum or airwaves more efficiently‚ enabling speeds of as much as 100 mbps (megabits per second) theoretically. Typically‚ 4G technologies don’t work on the switching systems used in mobile telephony but are deployed on Internet

3G vs. 4G: Real-world speed tests Just how much faster is 4G‚ anyway? We compare Sprint’s 3G and 4G networks. By Brian Nadel December 15‚ 2010 06:00 AM ET22 Comments. What’s this?.Computerworld - Mobile workers who need always-on Internet access -- and who don’t want to rely on public Wi-Fi hot spots -- often turn to a cellular network for connectivity‚ using either a 3G-equipped notebook or an external 3G modem. Now carriers are touting faster fourth-generation wireless networks as the next phase

ABSTRACT 4G TECHNOLOGIES Wireless technology has transformed our lives in many ways. Until very recently‚ we needed a computer wired to a port‚ to get online. Even wired telephones are becoming a thing of past. Nowadays‚ we use our mobile phones for banking‚ to check ticket availability at a Cinema Hall‚ and many more. Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires”. And‚ Wireless networking refers to any kind

3G vs 4G There has been more talk about 4G (fourth generation) mobile broadband recently and Nokia Siemens Networks (NSN’s) has announced that the first 4G field trials have been completed in Berlin. As 4G seems to have taken a step closer to reality‚ I decided to do some research and find out what advantages 4G may offer over 3G. The specifications for 4G are not standardized yet but the following 3G vs 4G table gives an idea of what 4G is likely to provide. Technology | 3G | 4G | Frequency

accessed and analyzed by concerned users. Managers simply need to know what the customers prefer‚ how much to store in the warehouse‚ how long should the assembly line be kept running; investors have to know whether their company’s stocks are doing well; and most people just want to keep updated about everyday events. So‚ clearly‚ there is the necessity for a technology that could make the world even smaller. And much better if all information needed by the user can be accessed easily and quickly

What is an OLED? • OLED (Organic Light-Emitting Diode) is a self lightemitting technology composed of a thin‚ multi-layered organic film placed between an anode and cathode. In contrast to LCD/TFT technology‚ OLED does not require a backlight. How does an OLED emit light? • OLED’s basic structure consists of organic materials positioned between the cathode and the anode‚ which is composed of electric conductive transparent Indium Tin Oxide (ITO). The organic materials compose a multi-layered
