What is 4G?
4G is the fourth generation of mobile telecommunications technology, commonly abbreviated as 4G, which are given by the Radiocommunication Standardization Sector of the International Telecommunication Union (ITU), whose task is to regulate most of the radio spectrum.
The 4G is populared now in North American, so GearBest sell the a lot of top brands 4G unlocked phone. However, some customers weren’t truly getting 4G unless they were in an area covered by a 4G network. Most places offer 4G now but when users with 4G devices are in areas offering only 3G, the device will switch over to 3G. Don’t worry, the smartphone will accept the 4G when you arrival the areas where 4G is strong.
4G data transmission speeds is better than 3G. 4G LTE wireless broadband is 10 times faster than 3G— whose download maximum speeds can reach 12 Mbps (Megabits per second) and upload speeds can reach 5 Mbps, with peak download speeds approaching 50 Mbps. In the other word, referring to 4G speeds, it is specified that the speed in motion must be at least 100Mb/s (approximately 12MB/s), while the speed when one is at a fixed point should be reach 1Gb/s (128MB/s).

What is LTE?
The acronym LTE stands for Long Term Evolution and is generally published as 4G LTE.
Although LTE is popularly considered as 4G, this technology is only one of this group, however, it is the most common when we talk about the latest generation of mobile internet.
This technology was created by the 3GPP (3rd Generation Partnership Project), which is a collaboration between associated telecommunication groups.
The LTE is the evolution of the GSM/UMTS standards, something with which we are a little more related and its purpose is to increase the capacity and speed of wireless data networks by using a new digital signal processing (DSP).
LTE is not 4G
Although generally the relationship of the LTE and the 4G works almost as synonyms. However the LTE is not 4G.
The first version of the LTE is commonly sold as "4G-LTE", but the problem comes because the specification of LTE does not meet the guidelines of 4G technology.
The LTE is known as pre-4G, since it offers more benefits than the characteristics of 3G, but does not fully meet the specification of 4G. One of the specifications most noticeable is in the speed, since theoretically it only reaches a peak speed of 100Mb/s.
Given the above, the LTE is a big change with respect to 3G, but for not meeting the standards of 4G is better defined as 3.9G, since it is neither 3G nor 4G, but is close to the 4G. In order to combat this weakness, 3GPP launched the new specification known as LTE-Advanced.
What is LTE Advance
LTE Advanced is the actual 4G candidate from 3GPP. This improvement for the LTE comes at the end of 2009. Unfortunately, the LTE in its eighth version was adopted as the international standard, while the Advanced has not yet had a great application.
The LTE Advanced, is version 10 of the LTE and complies with the speed characteristic proposed for the 4G, reaching 1Gb/s of descent speed.
