For a long time, although 5G as a new generation of communication technology has many advantages, including faster network speed, as well as a series of internet of everything such as smart home, telemedicine and a series of internet of everything ecology, the 5G era is also recognized in the industry as a new outlet leading the future. However, for the technical standards and specific solutions of 5G, telecom operators in different regions and places have always had their own opinions, at present, the mainstream two sets of solutions are divided into Huawei-led sub-6, and 5G millimeter wave that is recognized and promoted in the US market. So, which technical standard scheme between the two is better?
Now it seems that there is finally an answer.
Recently, according to foreign media reports, telecom operators in the United States that advocate the promotion of 5G millimeter wave have suffered serious losses. In fact, leading to serious losses in the promotion of 5G by local operators in the United States is a long-foreseeable result. After all, the characteristics of sub-6 and 5G millimeter wave two different standard 5G solutions are very distinct, unlike the sub-6 solution, 5G millimeter wave base station can only achieve a range of about 150 meters, which also means that if large-scale commercial, and to achieve full coverage of 5G signals, more numerous and denser 5G base stations are needed.
The result is obvious, the United States on the grounds of "information security" to resist the exclusion of Huawei, resulting in Huawei's 5G solutions and equipment can not enter the local market normally, and 5G millimeter wave, it is logical to become the preferred 5G solution for US operators. But now it seems that the United States telecom operators that fully promote 5G millimeter wave are not smooth in building a 5G ecology, due to the limited 5G millimeter wave base station signal coverage is small, the local operators in the United States have to invest more money to build more and more intensive 5G base stations, so that although it can improve the 5G signal coverage, but the number of 5G base stations increases, but also leads to a significant increase in the input cost of operators, coupled with the number of 5G users and ecology and liquidity at this stage is still in its infancy, high cost, less revenue With low profits, it is inevitable that US operators will lose money.
The United States 5G lost, the technical direction is deviated
It is undeniable that from the perspective of theoretical data, the 5G millimeter wave solution advocated by the United States does have the advantages of good performance and fast network speed. However, in contrast, the sub-6 cm wave scheme promoted by Huawei, although it is relatively conservative, the performance and network speed are weaker than the former, but the performance in actual application is diametrically opposite to the data.
5G millimeter wave, although the theoretical performance and network speed are faster, but the penetration, anti-interference ability is weak, the original signal coverage is small, in the building wall, rain and snow weather and other factors under the influence of more susceptible to affect, resulting in 5G signal greatly reduced. In contrast, Huawei's sub-6 cm wave scheme, which is not optimistic about the United States, is more stable in terms of penetration, anti-interference ability, performance and signal, and compared with 5G millimeter wave, the sub-6 cm wave scheme, which has absolute advantages in stability and signal coverage, can not only reduce the number and density of base stations, but also help operators reduce costs, and the signal coverage is larger, and the signal and network speed are more stable.
Huawei standards are the best solution
There is no harm without comparison, and at present, the sub-6 standard advocated by Huawei is the best solution. Although telecom operators around the world are generally rich, but the large-scale construction of 5G base stations is also a big expense, considering a series of follow-up costs such as technical maintenance, upgrades and labor, Huawei's sub-6 cm wave solution is obviously more suitable for large-scale 5G commercial use, in contrast, the higher cost, poor stability of 5G millimeter wave, obviously not the best solution.
Overall, the direction of the United States in the 5G strategy has deviated, which is a long-lost success for Huawei. After all, in recent years, Huawei has been limited by external force majeure factors, resulting in a situation in overseas markets that is not optimistic, and for 5G technology standard solutions, Ren Zhengfei has already given the best solution.
Previously, Ren Zhengfei made it clear in an interview with CCTV media that Huawei in 5G technology, others will certainly not be able to catch up in two or three years, 5G capacity is 20 times that of 4G, 10,000 times of 2G, power consumption is reduced by 10 times, volume is reduced by 70%, we have decades of materials that will not corrode, these characteristics are very suitable for Europe, and Europe communicates with us very closely. Unfortunately, although Ren Zhengfei's words have long been explained, but the US operators can't listen to it, now it seems that which plan is better, there is already an answer.
