3G and 4 G: what's different?
نوشته شده توسط : cheapweddingdresses

3G and 4G occur often in our lives, For average consumers, '3G' and '4G' are two of the most mysterious terms in the mobile technology dictionary, but they're used relentlessly to sell phones and tablets.

First things first, the "G" stands for a generation of mobile technology, installed in phones and on cellular networks. Each "G" generally requires you to get a new phone, and for networks to make expensive upgrades. The first two were analog cell phones (1G) and digital phones (2G). Then it got complicated.

Third-generation mobile networks, or 3G, came to the U.S. in 2003. With minimum consistent Internet speeds of 144Kbps, 3G was 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 phones are supposed 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.

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.

If you have a 3g smart phones and you've been frustrated with slow data, 4G may be the solution. 4G won't solve any dropped call problems, though, as all calls will be made over older networks until carriers switch to voice-over-LTE during the next few years.

If your smartphone is mostly for voice use, you have no need for 4G data. Save money and save battery life by choosing a device without the high-speed network.
