5G is generally seen as the fifth generation cellular network technology that provides broadband access. The industry association 3GPP defines any system using "5G NR" (5G New Radio) software as "5G", a definition that came into general use by late 2018. Others may reserve the term for systems that meet the requirements of the ITU IMT-2020, which represents more nations. 3GPP will submit their 5G NR to the ITU. It follows 2G, 3G and 4G and their respective associated technologies (such as GSM, UMTS, LTE, LTE Advanced Pro, etc.). The 5G is popular now in the world, it is a very remarkable technology.
Although this mobile telecommunications technology has not yet been officially popularized, some details are get out, such as remarkable speed and latency
5G NR speed in sub-6 GHz bands can be slightly higher than the 4G with a similar amount of spectrum and antennas.But some 3GPP 5G networks will be slower than some advanced 4G networks, such as T-Mobile's LTE/LAA network, which achieves 500+ Mbit/s in Manhattan.
The 5G specification allows LAA (License Assisted Access) as well but LAA in 5G has not yet been demonstrated. Adding LAA to an existing 4G configuration can add hundreds of megabits per second to the speed, but this is an extension of 4G, not a new part of the 5G standard.
Speeds in the less common millimeter wave spectrum can be substantially higher.
In 5G, the "air latency" target is 1-4 milliseconds, although the equipment shipping in 2019 has tested air latency of 8-12 milliseconds. The latency to the server must be added to the "air latency." Verizon reports the latency on its 5G early deployment is 30 ms.
5G communication frequency is very high, many people say, can I upgrade the firmware of my 4G phone to use 5G network? The answer is absolutely no! Most mobile phones on the market today cannot support 5G networks, including the mobile phone industry leader iPhone X.
Whether 4G mobile phones can use 5G and the system is irrelevant, because 5G is based on hardware view. 5G terminals are different from 4G. The antenna also needs to support the 5G frequency antenna. The network demodulator of the mobile phone processor also needs to support 5G. Perhaps the mobile phone card will welcome a card change, which will enable us to use the 5G network.
The use of 5G must rely on the chip of the mobile phone. Everyone knows that Snapdragon and Kirin are now equipped with 5G modules, such as Snapdragon 855 and Kirin 980. Kirin's current application range is only in Huawei mobile phones, and the opteron processor can be said to be the chip that all major manufacturers have been relying on. The current solution for 5G is the Snapdragon 855 plus the world's first 5G modem X50, which supports multiple 5G bands. At present, the three major operators have also announced that they will pre-commercially use 5G networks in 2019 for small-scale testing and use, and large-scale commercialization will wait until 2020.
At the China Mobile Partner Conference, Huawei, ZTE, OPPO, Xiaomi, and vivo, five domestic mobile phone companies have already demonstrated 5G terminal prototypes. This is no longer a simple model machine. Xiaomi's 5G version of Xiaomi MIX3 has been able to connect directly to 5G network, and shows the use of 5G Internet browsing and online video live broadcast.
Another demonstration of vivo is based on the Nex upgraded 5G prototype. The machine has also realized the function of HD live broadcast application. At the same time, the machine supports 100mhz broadband, and the peak speed is up to 1.7Gbits/s. This rate is already 4G. The network is 17 times faster, so when it is officially commercialized, the rate will definitely increase.
With the arrival of 5G, it is undeniable that the progress of science and technology and the development of society, everyone is full of expectations for 5G, but for the use of 5G, everyone is most concerned about the price of 5G mobile phones, and the details of 5G Internet access fees.
According to the news of the conference, the price of 5G mobile phones will be generally 725-1500 dollars next year. The cellular fees may stay ordinarily.
Do you await the time of 5G? It's not just mobile communication, our daily life will change more!
