Why doesn't Huawei p50 have 5g?

After the release of Huawei p50, it caused a lot of discussion. The focus is still 5 g. Many people don't understand why Huawei's leading 5g is not working now, so we can only use 4 G. Huawei, the first company to release integrated 5g baseband chips, can only make mobile phones without 5g after four rounds of sanctions.

The whole 5g network is a huge industrial chain, and no company owns all the industrial chains. The carrier network is the focus of Huawei, and the patents of 5g technical standards are also on the network. Microwave transmission is Huawei's strength. At present, what is stuck is mobile phone parts, manufacturing technology and operator network. Not only does Huawei not master RF and chip manufacturing, but other domestic companies have no substitutes, such as mobile phone memory chips and mobile phone processors. Screen. There are some substitutes in China, mainly the manufacture of mobile phone processors and 5g RF chips. The antenna used to send and receive information was stuck by foreign countries and there was no breakthrough. There was a chance. However, on May 15, Zhang Hao, the head of Si Nuo, went to the United States to attend an academic conference at the invitation of the United States. Zhang Hao is a leading figure in the field of MEMS filter chips, and has obtained seven patents in the United States.

Just landed, Zhang Hao was detained, and Zhang Hao fell to the United States for six years. During Zhang Hao's detention, Northrop discovered that the filter chips that Anhuagao sold to Apple used patented technologies developed by Pang Wei and Zhang Hao. At present, due to the lack of leaders, the development of Northwind is in trouble. The United States spares no effort to safeguard its technological hegemony. The means are lower.

It is very difficult to need a breakthrough in the whole industrial chain in a short time. No company can do it. Huawei is very willing to support domestic companies to make breakthroughs, so the screen is BOE instead of Samsung, and the storage is Changjiang Storage. It's hard enough to release p50. After Duolun sanctions, there are not many options. No company in the world can withstand such sanctions.
