The G of course means generation. Cell phones and systems are classified by the generation they belong to. Third generation (3G) phones were developed in the late 1990s and 2000s. 3G phone standards have been expanded and enhanced to further expand data speed and capacity. With minimum consistent Internet speeds of 144Kbps, they were supposed to bring "mobile broadband." There are now so many varieties of 3G, though, that a "3G" connection can get you Internet speeds anywhere from 400Kbps to more than ten times that. 4G suppose to be even faster, but that's not always the case. There are so many technologies called "4G and so many ways to implement them, that the term is almost meaningless. The International Telecommunications Union, a standards body, tried to issue requirements to call a network 4G but they were ignored by carriers, and eventually the ITU backed down. 4G technologies include HSPA+ 21/42, WiMAX, and LTE (although some consider LTE the only true 4G of that bunch, and some people say none of them are fast enough to qualify.) If you like to surf the Web and especially stream video, 4G can be heaven. If you connect a laptop to your mobile link, 4G makes a huge difference. In general, anything involving transferring large amounts of data gets a big boost from 4G. Watch out for the data limits on your service plan, though; it's easy to use up a lot of data very quickly with 4G.
