4G is simply a network used by mobile phones. It is upcoming for release in Europe in the foreseeable future and is intended to be the next step up in speed over the current 3G.
By 4g technology, I am assuming wireless internet access. MacBook's come with Wifi built in but not with 4G. Since there are several 4G service providers and each has a proprietary USB adapter, it is better not to have the 4G technology built in to the MacBook.
Cellular phone companies are advertising 4G as the next biggest thing in technology. Although you may have purchased a 4G phone, it may not necessarily run on a 4G network. Ensure that your area does in fact have 4G coverage (many areas do not yet, especially rural areas). Also, be sure not to go over your data plan usage limits, or your 4G will be slowed down to 3G.
what company develop 4g
The 4G network has not been completed and cellular service areas must switch to the 3G, however upgrades necessary are in progress and Verizon is one of the cellular service providers that has been leading the way in conversion to 4G.
No. A 4G phone typically is compatible with 3G networks, especially since 4G networks are not entirely established. 3G however is a lower generation technology that was created prior to the 4G so there just isn't a way to have the technology already in place for the newer.
4G technology refers to WiMAX and LTE Wireless Broadband technologies.
latest technology in communication slide should be 4G and 6th sense technology.
iPod 4G is better
There are many companies that offer the 4G network. It is offered by Verizon, AT&T and Sprint. 4G is the fourth generation of mobile communication technology standards.
4G is just the next step in cell phone technology standards after 3G. 3G came after 4G. It's the cell phone companys' way of coming out with the bigger and better thing to keep consumers wanting and buying.
usage of 3G and 4G technology..
It depends on what area you live in. For my area, AT & T offers the best coverage, but for some it is Verizon. Sprint is the only one who has a 4G netwrok, so if you are looking for internet browsing that would be best for you.
