What's the difference between 4G and 4G + networks
Sihai network: now 4G network of mobile phone has been basically popularized, sometimes faster than WiFi. Careful people will find that the area of mobile phone display network is sometimes 4G, sometimes 4G +, so what's the difference between 4G and 4G +? Let's take a look at what 4G + means.
The difference between 4G + and 4G on mobile phone
As 5g network is coming to the market, 3GPP, which is responsible for standard setting, has also recently made a high presence - not only 5g, but also 4G / 3G network standards. The first version of LTE (long term evolution) was compiled by 3GPP in 2008, but its maximum bandwidth, uplink peak rate and other performance parameters did not fully meet the requirements of 4G standard. It was not until December 6, 2010 that the International Telecommunication Union put LTE-A (LTE-A Advanced) is officially defined as 4G, and LTE-A is fully backward compatible with LTE, which can be upgraded through software, so it has become the only mainstream 4G standard now. (PS: another 4G standard is WiMAX advanced. LTE's early debut is largely to cope with WiMAX, but Intel's withdrawal in 2010 was almost abandoned by operators.)
From the above development process, LTE and 4G (LTE-A) are slightly different, and according to international standards, there is no 4G +. However, when domestic operators publicize LTE, they have already occupied the "4G" logo; therefore, after operators and mobile phone manufacturers officially support 4G, it is understandable to use "4G +" to distinguish them in order to show their own technology and equipment superiority.
[4G on mobile phone] - & gt; [LTE] - & gt; [3.9G]
[4G +] on mobile phone - & gt; [LTE-A] - & gt; [4G]
Although 4G + is only a small difference in logo, its performance improvement is quite obvious. Among them, carrier aggregation technology is of great help. Carrier aggregation is equivalent to the integration of continuous or discrete spectrum (bandwidth), and the integration of multiple 'small water pipes' into' large water pipes' for users to use (the actual technology is much more complex), so that the network speed is multiplied. In strict accordance with 3GPP standard, 4G is indeed better than LTE network in a narrow sense; however, in daily use, users generally can't enjoy the extreme network speed advertised by operators. Just know that when the mobile phone displays 4G +, the network speed will be better than when 4G is displayed. Don't pay too much attention to other details
