A 4G wireless network has a much faster internet speed than what 3G is capable of. Smartphone and laptop operators in such countries as South Korea and India that have a 4G network have noticed a huge difference between them. 3G wireless already has a faster download speed than 2G but 4G is even quicker. 4G wireless can download videos up to ten times quicker than 3G. When a large video is streamed online, such as a film, it won’t take as long on 4G when compared to 3G.
