As I have worked in cellular design long ago I might have something to add to what you find on google. But the basic answer is on google. What more did you need to know?
I know that downloading and uploading speeds available in 2G technologies are up to 236 Kbps. While in 3G technology speeds are up to 21 Mbps and 5.7 Mbps respectively. But how?
I need this for my research. Thanks in advance.
