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

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

for the large wireless mobile providers you’ll most likely hear about how their networks run on 4G and the ads make it sound like 4G is the greatest thing to happen to mobile devices‚ including cell phones and tablets. But is 4G really better then 3G or is it a lot of hype to get you to sign a new contract? Let’s examine the two systems. The G in 3G and 4G (and earlier versions) stands for "Generation"‚ which is really the generation of tech installed on your phone and at the wireless towers. As new
