Sun Jian directed Wang Xienian, Deng Zhongqiang, Zhu Zhijie, and Li Guoliang to invest funds, organize R&D personnel, and develop network communication equipment such as routers, modems, and network cards. Later, he established Shuguang Internet Equipment Company to produce Shuguang brand routers, modems, and network cards.
Today, Shuguang brand switches, routers, modems, network cards, hubs, bridges, routers, gateways, network interface cards (nic), wireless access points () and other network communication equipment with independent intellectual property rights are high-quality and low-priced due to their advanced technology. , with good after-sales service, it has occupied nearly 50% of the domestic market share, 40% of which is occupied by Cisco, Bell, Motorola, Ericsson, Samsung, IBM, Siemens and other companies.
Sugon Programmable Digital Switch Company, Sugon Communication Equipment Company and Sugon Internet Equipment Company under Sugon Communication Group have taken away the domestic market share of many Japanese and European and American communication equipment companies, and are regarded as a thorn in the side of Japanese, European and American communication equipment companies.
Sun Jian was not in a hurry when he received a call from Wang Xienian from the United States.
In his previous life, the Sun family was one of the first families in Jiangcheng to install ADSL broadband. In 1999, China Telecom launched a "Broadband Installation with Discounts to Welcome National Day" campaign. He forgot the initial installation fee and brought back an ADSL broadband router from the Telecom Sales Department. It is enough to replace the original isdn.
Adslmodem is installed in the telecommunications broadband box in the corridor. It uses digital encoding technology to obtain the maximum data transmission capacity from the existing copper telephone lines without interfering with the conventional voice services on the same line. It uses other than telephone voice transmission. The frequency transmits data, and users can make calls or send faxes while surfing the Internet without affecting call quality or slowing down the speed of downloading i content.
Starting from the National Day in 1999, as long as families could afford computers, they gradually installed adsl broadband. At that time, the Internet speed was as fast as lightning.
Zhu Zhijie and Li Guoliang were instructed to jointly develop the hardware system of adslmodem and broadband router, and Yan Yuanchao was instructed to develop the software system of adslmodem and broadband router.
Sugon Communications Group and Kunpeng Software Group are both listed companies. According to the tripartite cooperation agreement on adsl technology development, Sugon Communications Group will pay 1% of profits to Kunpeng Software Group and 10% of profits to Guozhi Semiconductor Group.
"Mr. Sun, after tcg obtains the company's invention patents for adslmodem and broadband router, the country will begin to promote adsl broadband business. tcg will transfer these two company invention patents to domestic and foreign network equipment companies at reasonable prices."
Minister Wu admired in his heart. According to industry estimates, the overall strength of Sugon Communication Technology Research Institute and Guozhi Semiconductor Research Institute has surpassed the Wireless Communication Technology Research Center under the Chinese Academy of Sciences and the Telecommunications Science and Technology Research Institute under the former Ministry of Posts and Telecommunications. Not only have they successfully developed Adsl technology with independent intellectual property rights, and also took the lead in successfully developing 3g mobile communication technology and tdscdma with independent intellectual property rights.
"Okay, Minister Wu!"
Everyone carries the sedan chair, and even with the company's invention patent for adsl, Dawn Communications Group cannot be left alone.
The installation of adsl broadband will be dominated by China Telecom and China Netcom, with Sugon Communications Group being just one of the network equipment providers.
"Mr. Sun, I have good news for you. The draft TDSCDMA recommendations organized by Academician Ye have been submitted to the International Telecommunications Union. We can only wait for good news."
"Congratulations to Minister Wu!"
With the passage of time and the development of mobile communications, e-technology can no longer meet users' needs for larger capacity and higher data rates. It can provide some packet data services, such as sending and receiving emails, TP, EB browsing, etc., but for services containing Contents such as images and sounds, such as vod, online audio-visual, and real-time video image transmission, require data services with wider bandwidth access and are difficult to provide.
In March 1998, the U.S. tiatr4. committee adopted a backward-compatible is9 broadband cdma framework called cdma2000, and submitted it to the International Telecommunications Union (itu) as the third-generation mobile communications air interface standard.
The goal of cdma2000 is to provide a higher data rate to meet the performance requirements of imt2000, that is, at least 144b/s in a driving environment, at least 384b/s in a walking environment, and at least 2048b/s in an indoor office environment.
The goals of imt2000 are: high consistency in design around the world; mutual compatibility with various fixed network services; high service quality; small terminals used globally; terminals with global roaming capabilities; terminals that support multimedia functions and a wide range of services .
In order to achieve the above goals, the third generation wireless transmission technology rtt puts forward basic requirements such as supporting high-speed multimedia services in high-speed mobile environment: 144bps, outdoor walking environment: 384bps, indoor environment: 2mbps, and having higher spectrum efficiency than existing systems.
At the end of 1996, under the leadership of the Ministry of Science and Technology, the Ministry of Posts and Telecommunications, and the Chinese Academy of Sciences, radio communication technology experts and professors from domestic scientific research institutes and enterprises were organized. After full demonstration and in accordance with the specifications and standards compiled by the International Telecommunication Union ITU in 1996, it was decided to develop independent The 3G communication technology standard for intellectual property rights is initially named dtscdma.
In early 1997, itu issued a circular letter requiring all countries to submit candidate imt2000 wireless interface technology solutions before June 1998.
tdscdma is the abbreviation of time division synchronous code division multiple access.
The state allocated a huge sum of 40 million yuan and handed over the task of developing a 3G communication system with independent intellectual property rights to the Communication Technology Research Center of the Chinese Academy of Sciences, the Telecommunications Science and Technology Research Institute of the former Ministry of Posts and Telecommunications, Datang Telecom, and Sugon, a subsidiary of Shuguang Communications Group. The Communications Technology Research Institute and Julong Information Company, each with 10 million yuan, organized their own R&D personnel to carry out research in accordance with the IMT2000 standards.
Sugon Communications Group invested another 0 million yuan, with Sugon Communications Group as the main body. Ye Mingxin, consultant of Sugon Communication Technology Research Institute and academician of the Academy of Engineering, was appointed as the consultant of the joint research group. Zhu Zhijie, president of the Sugon Communication Technology Research Institute and academician of the Academy of Engineering, was the team leader. Kunpeng Software Yan Yuanchao, dean of the institute and academician of the Academy of Engineering, is the deputy team leader, and Li Guoliang, dean and researcher of Guozhi Semiconductor Research Institute, is the deputy team leader. They organized the elites of the three institutes to carry out joint research and development to strive for the first successful research and development.
Living up to expectations, in July 1997, Sugon Communications Group took the lead in successfully developing tdscdma.
Through optimal adaptive resource allocation and optimal spectrum efficiency, tdscdma can support various 3G services such as voice, video phone, and Internet at rates ranging from 8b/s to 2mb/s and higher.
After demonstration by a joint expert group, the tdscdma successfully developed by Sugon Communications Group has smart antennas, synchronous code division multiple access, relay switching, and time division duplex as its main features. It complies with the IMT2000 standards and will serve as the blueprint for China's application for 3G communication standards.
Members of the expert group immediately drafted a tdscdma proposal that meets the requirements of imt2000, and the standard will be submitted to the International Telecommunications Union itu.
Academician Ye Mingxin serves as the leader of the expert group for drafting tdscdma recommendations. Zhu Zhijie and Li Guoliang are one of the experts on the drafting expert group.
