Homework 7 3G/4G

3G refers to the 3rd generation of mobile technology that brings forth an international mobile telecommunication. 4G refers to the 4th generation of mobile technology. As we all know the new and latest 4G technology was released not some long ago. However, can we really call it 4G? Looking at your mobile 4G device does it really have 4G every place you go? The answer is no. This is because the "4G" carriers also carry 3G. When the 4G access isn't around the mobile device will use 3G instead. In most cases your mobile device is using 3G which is significantly slower. Major cities are just about the only spot where one can access full 4G. I feel after the whole nation wide 4G comes around finally we will be hooked on to another great invention such as nation wide wifi.
