4G is 4th generation abbreviation and is the fourth generation of mobile telecommunications standards. It is the successor to the 3G standard that reached its peak in 2010 with 3.9G, also known as Pre-4G. 3G was the first communication protocol where one began to speak of "generations", a term that has become a convention in the meanwhile.
The speed of 4G is 100 Mbit / s (converted 12.5 MB / s) by train or car and 1,000 Mbit / s (converted 125 MB / s) during walking or stopping. Among other things, due to these high demands on speed, there is currently only one standard that, according to ITU, meets the requirements for 4G: LTE Advanced. Mid-2013 only a commercial 4G network was active in South Korea. The currently active 4G networks currently in the rest of the world are actually 3.9G, see below.
However, many manufacturers have marketed their 3.9G products with names suggesting that they are 4G products. For example, 3GPP has acquired Long Term Evolution as a "4G-LTE" brand name and prices for Dutch telecom providers who have a network based on this standard are often called a "4G network." However,
4G is not completely uncontroversial. Due to fear of health risks, the Brussels region had strict radiation standards until the beginning of 2014, which prevented 4G from being operational.
Download Speed 4G (LTE Advanced) FrequenciesFrequently used frequencies for 4G are in: LTE-Advanced
(Long Term Evolution Advanced) is a standard for mobile communication. The standard is an extension of 3GPP Long Term Evolution. LTE-Advanced's technology is the same basic technology as LTE, making LTE-Advanced like LTE a 4G Technology. The thoughts behind LTE-Advanced are to add more spectrum to an LTE signal or to combine spectrum from two different tires, making more transport speeds available to the UE. Additionally, with a larger number of antennas, it improves the propagation of the radio signal. These two techniques are called Carrier Aggregation and MIMO. These two techniques are the main drivers for LTE-Advanced. Radio technology and Corr networks do not change because this would be an overestimated investment for network operators after the LTE rollout. Hence the name LTE-Advanced is nothing more than an upgrade from LTE, which clearly makes this a 4th Generation technology, like LTE.
It is expected that, in the course of 2015, Terminals will be available generically and that around these time networks LTE Advanced will begin to roll out over larger areas than just large cities or pilot projects. On this basis, you could expect LTE Advanced to commence in 2016. The most important driving force for LTE Advanced will be the hunger for Mobile video streams by end users, for most other types of content, LTE is sufficient and does not offer LTE Advanced any award for operators.
LTE-Advanced can therefore reach speeds up to 3 Gbit / s. This is 30 times as fast as the original LTE. The development of LTE-Advanced is not silent in the Netherlands. LTE Advanced is available at KPN, Vodafone and Ziggo at a speed of 225 Mbit / s. KPN, Vodafone and Ziggo have no national coverage with LTE Advanced. T-Mobile has a nationwide LTE Advanced network since 16 June 2016. Goals Important technologies Future
LTE-Advanced can be used as an enhanced version of the 3GPP standard LTE in 4G. Compared to other wireless communication standards, LTE-Advanced is an important step forward. It certainly sets high technical indicators. There is no doubt that LTE-Advanced will become one of the most important forms of mobile communication in the coming years, it will certainly promote further development for the next generation of mobile communications.
