What is 4G mobile technology?

Fourth generation mobile technology (4G) is a set of standards for the provision of broadband Internet access to devices such as mobile phones and tablets. Although it was first available in the US in 2009, no specific technologies were officially labeled 4G until 2011. Nevertheless, many devices have been marked as "4G", although they have not met the Standards of the International Telecommunications Union (ITU) for this technology. The main difference between IT and previous standards is the large increase in data transfer speed and the types of media people have access to it.

Function

General features for mobile 4G mobile technology are set at international standards of mobile telecommunications in Advanced (IMT-A) written ITU. According to IMT-A, 4G mobile devices must be based on IP and capable of providing data speeds of up to 100 megabits per second (MBPS) when the device is used when moving and up to 1 gigabit per second (GBPS) when it is stationary. All devices must also be able to be usedT for digital voice and rich media, which includes things such as websites with video streaming or expandable banners. In addition, it must provide certain types of security for transmissions.

There are also a number of technical specifications, including things such as wireless standard, the use of frequency and frequency spectrum. Since 2011, there have been only two technologies officially marked as 4G Mobile: LTE-Advanced and Wimax Release 2. Although devices using these technologies can theoretically achieve data and requirements for the functionality of the established ITU, the actual function differs according to network coverage, infrastructure and location.

Other versions

The former version of LTE and Wimax and other technologies called HSPA+are also commonly referred to as 4G; Despite the name, no one actually meets the standards set out in IMT-a.Tetechnology have been launched as often as "4G" that ITU upossible to require the designation. Most of the main carriers in the US work with at least one of these standards, some support both. In general, LTE services are faster than Wimax, but Wimax can often support a long -distance signal than LTE, which means that the user could use mobile devices further from hotspot. In addition, LTE is primarily used for mobile phones and similar mobile devices, while Wimax is sometimes used to ensure home internet connection.

Compared to 3G

The main difference between mobile 4G mobile technology and the previous standard, 3G technology in terms of final use, provided data transfer speeds are provided. This means that users have access to much more sophisticated data that requires a large bandwidth very quickly. Depending on the service provider, however, the 4G mobile device may be limited to specific zones for making phone calls that are generally smaller in areas covered with 3G. It means that people whoare trying to call, they would drop from their call if they went outside the covered area. Some 4G phones also have much shorter battery life than most 3G phones.
