5g technology is very powerful, so now 5g technology is unique to Huawei?

With the advent of the 5G era, countries all over the world are competing for the right to formulate 5G standards. According to the current development, China is likely to lose the rights of the 5G standard. This paper discusses the formulation of standard rights in the future 5G era from the development of mobile network standards. There are many related standard terms in the article, which can be simply considered as network standards of different times and will not affect reading. For a detailed explanation, please refer to: Why are we all using castrated mobile phones?

When the 3G standard was formulated, the United States and South Korea dominated the development of CDMA technology, defining the 3G standard as CDMA2000, and Europe revised CDMA to introduce WCDMA. However, because the core technology is CDMA, Qualcomm still has a strong patent advantage in WCDMA standard. The dispute between Europe and America and the neglect of China's TD-SCDMA make China's TD-SCDMA one of the 3G standards.

Formulation of 4G standard. In 2004, Europe and China jointly developed 4G technology, named Long Term Evolution. In order to continue the technical advantages of WCDMA, Europe actively promotes LTE-FDD of frequency division technology to become the 4G standard; China promotes TD-LTE to become a 4G standard. In order to bypass Qualcomm's patent advantage, China and Europe cooperated closely and put Qualcomm aside in the LTE feasibility study stage from 2004 to 2006. Later, OFDM and SCFDMA were selected as the core technologies of 4G.

Qualcomm was arrogant at that time, and continued to develop its own CDMA Rev.B. In 2006, the feasibility study between China and Europe was completed. In order to continue the advantages of CDMA technology, Qualcomm launched its own 4G standard, named CDMA REV.C The core technologies are CDMA and OFDM. CDMA REV.C was later renamed as UMB, but it was forced to quit in 2008 due to technical defects. At the same time, another American high-tech giant, Intel, is pushing WIMAX with the same time division technology as TD-LTE. However, due to Intel's failure to coordinate the interests with Qualcomm, in 20 10, Qualcomm and Ericsson expressed their support for TD-LTE at the same time, which led to WIMAX's premature death!
