3G
One of the hottest and revolutionary technology to hit the market in the 21st century in the mobile communication world is the 3G technology. 3G technology allows mobile users to surf internet share media files, check emails, and do video conferencing besides many other activities. The term 3G’ means ‘3rd Generation’ in mobile phone technology. 3G technology enables data transfers at high speed between wireless phones.
3G is the third generation of mobile technology, which dominates the other two generations. Generation one was simply just a channel that carried voice over an 800 MHz frequency band. It was revealed to the public around the 1980’s. Phones around this time were nicknamed “the brick” only because it resembled one. Being very heavy and very bulky. The second generation was a little more complex where cell phones could be used all over Europe and allow travelers to use their phone anywhere on the go. This was achieved by Global systems for mobile communications (GSM), and using time division multiple access. 2G worked well enough for voice and it provides data rates up to 9.6kbps. This data transfer could not support what we do now with our phone, like E-mail, picture messaging, file transfers. There wasn’t enough bandwidth to support this in the 2G network.
Now and days every phone is at least at the 3G level if not higher. Looking at any phone now we see that they are all 3g capable. They can get e-mail, send movie clips, surf the web and can do three way calls. The phone that uses this the most is Blackberry and the I phone. Through this technology these phones were able to utilize what 3G offered and made their phone with what everything that could be used.
