A lot of cell phones advertise that they provide 3G, or third generation, wireless network connections. The 3G connection offers a faster, wider range of wireless and Internet services than earlier generation cell phones.
Download/Upload
With a 3G network, you can download 14.4 megabits of data per second and upload 5.8 megabits of data per second on average.
Layers
The 3G network runs a layered system of information. The first layer is the general service, the middle layer controls data transmission, and the third layer contains basic connectivity information.
Wi-Fi vs. 3G
A Wi-Fi connection is a short-range wireless Internet connection, while 3G is designed specifically for cell phone technology and Internet access.
First 3G
A Japanese company developed the first 3G network in May 2001, followed by a South Korean company in 2002.
Frequency
The 3G network uses a different radio frequency than the previously used 2G network, so many countries had to build a new infrastructure before 3G became basically worldwide by 2007.
