In the previous life, in 2000, the International Telecommunication Union ITU officially announced the third generation mobile communication standard. The tdscdma submitted by China officially became the 3G international standard. Together with the cdma submitted by Europe and cdma2000 submitted by the United States, it became one of the three most mainstream technologies in the 3g era. Written into the 3G technical guidance document "International Mobile Telecommunications Plan 2000, referred to as imt-2000."
In his previous life, Sun Jian didn't know who invented tdscdma? It should be related to the predecessor of Datang Telecom, Telecommunications Science and Technology Research Institute. I thought TD was the abbreviation of Datang.
In a previous life, I read articles about tdscdma on the Internet.
In a previous life, in 1997, at the Xiangshan Conference on China's 3G standards, the Ministry of Posts and Telecommunications, which presided over the meeting, came up with a 3G solution with tdscdma as the core and handed it over to the experts, professors and operators who attended the meeting for discussion.
Operator representatives have two opinions: One opinion is based on the operator's perspective, hoping that there will be only one 3G standard in the world. Now there are two major standards in the world, cdma and cdma2000. If China proposes another tdscdma standard, it will be detrimental to the 3g standard. Unite. Another opinion is mainly based on national interests, hoping to take advantage of the opportunity of 3G standardization to establish its own 3G standards, so as to promote the rapid development of China's communications industry.
Finally, the 3G group headed by Vice Minister Song of the Ministry of Posts and Telecommunications made a favorable opinion to encourage the submission of its own 3G standards.
The first standard of tdscdma was completed around January 1998, and then it took about a month to revise and improve it. Until June 30, the deadline for the International Telecommunications Union to submit the 3g standard was only one week away, the government still Still haven't made the final decision on whether to submit your standards? The day before the deadline, the Ministry of Information Industry submitted the tdscdma standard proposal to the International Telecommunications Union via email.
At the end of 1998, the International Telecommunications Union conducted a preliminary review of the 3G standard. Among the 10 alternatives, tdscdma was not eye-catching. Almost all international mobile phone manufacturers were not interested in this unfamiliar standard. However, after the Ministry of Information Industry sent a letter to various foreign companies in China, Faced with the huge potential of the Chinese market, these multinational companies changed their attitudes and tdscdma was able to pass the review.
Due to the rush of time and many loopholes, tdscdma had to turn to Siemens, which owns tdcdma standard technology, to continuously improve the tdscdma standard technology.
In the competition for the European 3G standard, the tdcdma camp headed by Siemens and France Telecom lost to the cdma camp headed by Ericsson and Nokia, and cdma became the European 3G standard.
Due to the setback of Siemens' tdcdma, I have always been worried about it.
Finally, when the Ministry of Industry and Information Technology allocated 3G licenses, China Unicom got the most mature cdma standard, China Mobile got the least mature tdscdma standard, China Telecom got the cdma2000 standard, and finally the tdscdma standard delayed domestic 3G commercial operations. hind legs.
Sun Jian is not worried at all. Can tdscdma become one of the three major international standards for 3G?
Sugon Communication Technology Research Institute and Guozhi Semiconductor Research Institute began to develop the 3G standard for cdma in 1994, and successfully developed tdscdma in June 1999, but it was not announced.
In March 1996, according to the IMT2000 technical standard compiled by the International Telecommunication Union ITU in 1996, it was revised to comply with international standards and was not announced to the outside world.
In the end, the Ministry of Posts and Telecommunications organized four units to develop China's 3G standards and tdscdma, and Sugon Communications Group was the "first" to successfully develop them.
3G communication chips, 3G base stations, 3G hardware testing equipment, etc. have been developed or are under development.
Shuguang brand 3g mobile phone has been successfully developed!
Sugon brand 2G mobile phones now account for 80% of the domestic high-end mobile phone market, 3.6% of the Southeast Asian mobile phone market, 11.3% of the US mobile phone market, 9.4% of the EU mobile phone market, 7.6% of the Japanese mobile phone market, and 6.8% of the Korean mobile phone market.
A weak country has no diplomacy!
Even those who are advanced will be beaten!
Get rich silently!
Even if Shuguang Communication Technology Research Institute is the first to successfully develop the 4G standard, Sun Jian is not allowed to announce it, otherwise he is seeking death!
Once the tdscdma technology with independent innovation and independent intellectual property rights is recognized by itu, China will occupy a place in the global third-generation mobile communication technology field and keep up with the pace of 4g development.
tdscdma was hosted by the former Ministry of Posts and Telecommunications, assisted by the Ministry of Science and Technology and the Chinese Academy of Sciences, and successfully developed an innovative 3G communication technology specification standard with independent intellectual property rights. However, the hardware and software technology of tdscdma were mainly developed by Shuguang Communications Group. The former Ministry of Posts and Telecommunications also Sorry, I just grabbed it.
After some haggling, the leader of the 3G leadership group and former Vice Minister Song of the Ministry of Posts and Telecommunications made the final decision.
tdscdma has become a company invention patent signed by many people. Sugon Communications Group is the first inventor, the Wireless Communication Technology Research Center of the Chinese Academy of Sciences is the second inventor, and Datang Telecom and Julong Information Company are tied for the third inventor.
Through a written agreement, the four units own 60%, 20%, 10%, and 10% of the rights and interests of tdscdma Company's invention patent respectively. The four units produce products related to tdscdma Company's invention patent and do not need to pay patent royalties. The other units produce related products. Patented products require patent royalties to be paid to Sugon Communications Group.
Sugon Communications Group pays patent royalties to the other three units every year based on the equity ratio of the four units.
In the previous life, in June 2000, three Japanese operators obtained the right to operate 3G services, becoming one of the first countries in the world to launch 3G services.
In China, due to various reasons such as the hardware, software and network required by tdscdma, it was not until April 1, 2008 that China Mobile launched the third-generation mobile communication 3g Chinese standard tdscdma social service in big cities such as Beijing and Shanghai. Testing and pre-commercial use.
In the previous life, 2009 was called the first year of China's 3G, which was eight years later than Japan and three years later than the United States.
In the previous life, at the end of 2008, China's 4G standard was released, only one year later than the United States.
"Minister Wu, the American AOL company rented a communication satellite from the American Hughes Company last year and launched aerial broadband services in the United States; even if the International Telecommunications Union agrees that dtscdma will become one of the 3G standards, I estimate that it will take at least about a year for domestic 3G to be officially commercialized. time, it is urgent to develop communication satellite networks! This is the long-term plan for satellite launch and operation formulated by Star Commercial Satellite Company and Star Satellite Operation Company, written by researcher Huang Zhicheng, chief scientist of Star Commercial Satellite Company. It is called the 'Symmetry Plan'. Please read it. , please help transfer it to the relevant leaders.”
Sun Jian took out the printed symmetrical plan from his briefcase and handed it to Minister Wu with both hands.
Launch 88 low-orbit satellites, composed of many stratospheric aircraft and ground service stations, to cover the earth and cover wireless networks at any point within 8 degrees north and south of the world for 3G communications and television program broadcasting.
The "Symmetry Plan" was handed over to him personally by Mou Dazhong and was designed by researcher Huang Zhicheng. Mou Dazhong organized experts and professors to conduct a feasibility study. The total investment was estimated to cost tens of billions of yuan, which was an astronomical figure at the time!
