Many senior executives, including Zhang Jilin, Yan Yuanchao, Liu Zhenhua, Lin Qifeng, Zhong Dewei, Deng Yuning, Xu Xinhua, Li Hengtao, Zhou Hongwei, Zhou Daming and Li Ting, all graduated from Huazhong University. In January 1994, as outstanding alumni and outstanding teachers, Donated 10 million yuan to build the Shuguang Communication Technology Experimental Building at Huazhong University. It has already been put into use and has become a landmark building of Huazhong University.
Taobao Holdings arranges about 100 interns from Huazhong University every year and selects the best graduates. Today, the company has more than 800 graduates from Huazhong University.
Sun Jian is also an old acquaintance with Principal Zhou and Vice Principal Fan.
The Ministry of Education and Hubei Province hope that Huazhong Medical University will merge with Jiangcheng University to build Jiangcheng University into a world-class university. However, a group of leaders of Huazhong Medical University quickly "marriaged" with Huazhong University without extensive consultation. ”.
There are rumors that Jiangcheng University’s refusal to retain the “Huaji” brand and its independent management rights in terms of people, finances, materials, foreign affairs, etc. is an important reason why Hua Medical University is unwilling to merge with Jiangcheng University. The province came forward and Jiangcheng The university later chose to merge with the Hubei Medical University.
Huazhong University and Jiangcheng University are famous universities in Hubei Province that rank among the top 10 universities in the country. Huazhong University is famous for science, and Jiangcheng University is famous for liberal arts. Taobao Holdings has more than 400 graduates of Jiangcheng University.
Company executives such as Liu Yue, Xiang Dongping, Zhu Junsong, Li Weimin, Zhong Guohua, Ye Yongjun, Yan Qiuhong, and Guo Yuchen are all from Jiangcheng University.

Hong Zucheng, director of Sugon Smartphone Research Institute, held a black mobile phone in his hand and introduced it to Sun Jian. He could not restrain his inner joy. Compared with this mobile phone, the 3G mobile phones successfully developed on the market are not only better in performance, but also in appearance. On the other hand, he is far from his opponent.
On May 19, the first-generation Sugon 3G mobile phone with cdA technical standards was successfully developed at Sugon Mobile Phone Research Institute. Sun Jian received the good news from Wang Xienian and took the opportunity to fly to the headquarters of Shanghai Shuguang Communication Group to congratulate him.
"Congratulations to Director Hong. On behalf of Sugon Communications Group, I award Sugon Smartphone Research Institute 5 million yuan."
Bang bang...
"Thank you, Mr. Sun!"
…
On May 11, the International Telecommunications Union (ItU) determined the three mainstream wireless interface standards - cdA, cdA2000 and td-ScdA, and wrote them into the 3G technical guidance document "International Mobile Telecommunications Plan 2000" (referred to as It-2000).
-cdA, also known as cdA, is a 3G technical specification developed based on the GS network. It is a broadband cdA technology proposed by Europe. It is basically the same as the broadband cdA technology proposed by Japan. Its supporters are mainly European manufacturers based on the GS system. Japanese companies are also more or less involved, including European and American Ericsson, Alcatel, Nokia, Lucent, and Nortel, as well as Japanese manufacturers such as Ntt, Fujitsu, and Sharp. This system can be set up on the existing GS network. It will be easier for system providers to transition, and Asia, where the GS system is quite popular, is expected to be highly receptive to this new technology. Therefore, -cdA has an inherent market advantage.
cdA2000 is a broadband cdA technology developed from narrowband cdA (cdAIS95) technology. It was proposed by Qualcomm North America, with Motorola, Lucent and Samsung participating. This system can be directly upgraded from the original cdAone structure to 3G, with low construction costs. It is cheap. The regions that will use the cdA standard are Japan, South Korea and North America. There are not as many supporters as -cdA. However, the research and development technology of cdA2000 is the fastest among the current standards. Many 3G mobile phones have already been launched.
The td-ScdA standard is independently developed by mainland China3
G standard was jointly proposed to ItU on June 29, 1999 by Sugon Communications Group, Wireless Communication Technology Research Center of China K Academy, Datang Telecom Company and Julong Information Company. This standard integrates today's leading international technologies such as intelligent wireless, synchronous cdA and software radio. It has unique advantages in spectrum utilization, flexibility in business support, frequency flexibility and cost. Due to China's huge communication market , this standard has attracted the attention of major telecommunications equipment manufacturers, and more than half of the world's equipment manufacturers have announced that they can support the td-ScdA standard. This standard proposes a direct transition to 3G without the intermediate link of 2.5 generation, which is very suitable for the upgrade of GS system to 3G.
td-ScdA 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 organized Shuguang Communications Group, the Wireless Communication Technology Research Center of the Chinese Academy of Sciences, Datang Telecom Company and Julong Information Company to successfully develop innovative 3G with independent intellectual property rights. Communication technical specifications and standards.
In July 1997, Sugon Communications Group took the lead in successfully developing td-ScdA (including hardware and software). After some bargaining, the leader of the 3G leadership group and former Vice Minister Song of the Ministry of Posts and Telecommunications finally decided that Sugon Communications Group was the first to develop td-ScdA. The inventing unit, Wireless Communication Technology Research Center of the Chinese Academy of Sciences, is the second inventing unit, and Datang Telecom Company and Julong Information Company are tied for the third inventing unit.
Through a written agreement, the four units own 60%, 20%, 10%, and 10% of the rights and interests of td-ScdA Company's invention patent respectively. The four units produce products related to td-ScdA Company's invention patent and do not need to pay patent royalties. Other units producing related patented products need to pay patent royalties 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 July 1997, after Sugon Communication Group successfully developed the td-ScdA technical standard, in order to speed up the research and development of third-generation communication standard mobile phones, Sugon Communication Technology Research Institute established Sugon Smartphone Research based on the team that developed the SG-3303GS mobile phone. The institute consists of a smartphone design department, a smartphone marketing department and a smartphone quality inspection department. Researcher Hong Zucheng serves as the director, and researcher Deng Qing serves as the deputy director.
The research and development of Sugon's third-generation communication standard mobile phone is a systematic project, which also includes Guozhi Semiconductor Research Institute, Guozhi Mobile CPU Research Institute, Guozhi Mobile Motherboard Research Institute and Kunpeng Software Research Institute, Kunpeng Mobile 0S Research Institute, respectively responsible for Development of hardware and software for Sugon smartphones.
In April 1998, Sugon Smartphone Research Institute successfully developed the first generation Sugon 3G mobile phone with td-ScdA technical standard. It was equipped with Guozhi 3G mobile phone CPU and Kunpeng 3G mobile phone operating system. It used Seiko brand 3.5-inch LCD touch screen and the back was made of plastic material. , has a Zeiss brand 2 million pixel rear camera, a built-in Chaoyang brand 1150 mAh removable lithium battery, 4G, 8G memory, 75 mm width, 115 mm length, 15 mm thickness, and weighs about 180 grams.
At that time, because the 3G international standard was still under discussion, there was no 3G network in the world, and 3G mobile phones had no place to use it. The first-generation td-ScdA technical standard Sugon 3G mobile phone was not put into production and became the first generation cdA technical standard to be developed. The membrane board of Sugon 3G mobile phone.
Sun Jian knew that Japan was the first country in the world to commercialize 3G networks and that Japan adopted the cdA technology standard. He suggested that Japan continue to develop the first generation of 3G mobile phones with cdA technology standards.
