A year later
In 2021, the smartphone manufacturer that the public is most sorry for is Huawei, because it has the most advanced 5G technology, and also has the world's most 5G patented technology, and it is the world's first manufacturer to successfully release 5G smartphones, but due to the impact of related restrictions, Huawei has 5G technology but cannot release 5G mobile phones.
In this link, the participation of 5G RF chips is missing, and it should be known that the existence of RF chips is to "interact" with the base station, by sending and receiving 5G signals on smart phone products, and finally realizing the connection of 5G networks.
However, because the innovation of each generation of communication networks will use a new frequency band, so the corresponding RF chip must also be iteratively upgraded, otherwise it will not be possible to send and receive a new communication network, the current Huawei mobile phone is only 4G RF chip, so the transceiver is also 4G signal, and 5G RF chip because domestic mobile phone manufacturers have mostly relied on imports before, so there is a certain gap in the domestic market, which is why Huawei can not launch 5G smart phones through the domestic industry chain.
However, just when the outside world is worried that Huawei will lose its competitiveness simply by relying on 4G mobile phones, the arrival of a new news on March 2 seems to mean that the key moment of domestic RF chips has come.
Because, according to relevant media reports, Huawei recently officially announced a "RADIO frequency chip, baseband chip and WLAN device" patent, the emergence of this patent seems to mean that Huawei has achieved a technological breakthrough in the field of related RF chips, and from the perspective of the patent applied by Huawei, this RF chip patent is a brand new patent, there is no possibility of including American technology, Huawei will be able to use it with confidence, and it should be noted that In the field of RF chips, Huawei has only been in a year since scratch, which shows the strength of Huawei's research and development capabilities.
It's finally here
Originally, the outside world thought that Huawei's way to solve the 5G RF chip would be achieved by cultivating manufacturers in related fields in China, after all, Huawei's Hubble investment has been investing in manufacturers in the domestic chip field, but did not expect that this time it was Huawei himself.
With the release of this news, for the development of Huawei's 5G smart phone is also a great positive, although at this stage Huawei has not specifically announced whether the relevant patent of this RF chip is a 5G RF chip, but, not surprisingly, it can basically be determined that it is the RF chip of the benchmark 5G, because the current Huawei released smart phone products have been equipped with RF chips that can send and receive 2G, 3G, 4G, there is no need to engage in an exactly the same product out. Therefore, this time the patent is most likely to go to the 5G RADIO frequency chip.
Of course, the technology is still in the patent stage, as for when it can be officially commercialized, it still needs Huawei to personally answer, but in any case, Huawei's breakthrough in the field of RF chips means that it is finally coming.
At present, Huawei is solving the supply chain vulnerabilities on Huawei's mobile phones step by step, as long as these vulnerabilities are replaced by localization, then Huawei's smartphone business will also start to take off again, and it will realize the scene of the return of the king, which is also emphasized by Yu Chengdong, CEO of Huawei's consumer business, in an internal meeting last month.
summary
Although since 2019, Huawei has been encountering business difficulties, but Huawei has never bowed its head, but under the leadership of Mr. Ren Zhengfei, it has continuously launched the "spare tire plan", step by step to make up for the shortcomings in the supply chain, and migrate the supply chain to the domestic market on a large scale.
And in this process, Huawei has gradually established a new set of framework system, from the operating system to hardware products have gradually removed the "European and American standards", and established a new standard system that belongs to the mainland market, which is good news for the global market.
After all, only the standard of European and American standards is definitely not a good standard.
