Shenzhen YD Electronics was reported by the “New Focus” Program of Guangdong Economic Channel

Along with the development of whole country, our Guangdong province, which is in the forefront of reformation and opening, has went through 70 years hardships and difficulties, and wrote a brilliant chapter for development. On this occasion, our program launched a special series of interview - “Technology leads the future, industry pioneers” - to celebrate China’s 70th anniversary, by focusing on a batch of leading enterprises in scientific and technological innovation. Today, let’s work into Shenzhen YD Electronics Information Co., Ltd., which is listed in the first batch of enterprises to set up Guangdong provincial academician workstation (enterprise) in 2019, which is also the top company in the competition of 5G applications in vertical industries organized by MIIT (the Ministry of Industry and Information Technology of the People's Republic of China), and let’s learn how this company stands out in the competition of the huge market.

Shenzhen YD Electronics was founded in 2001, it is a national high-tech enterprise that has been focusing on the research and development of computing system and computing method, and the industry applications. At present, the company has branches and offices in most of the major cities, and its sales and service system covers all the country. As a pioneer of software-defined concept in China, Shenzhen YD Electronics has made great contributions to the country’s security equipment and the industry development, and based on strong computing capabilities, it has created many No.1 in the industry. The “Network security system for ‘China Railway Ticketing and Reservation System’ (12306)” independently developed by Shenzhen YD Electronics in 2002 was successfully listed as the demonstration project for the National 863 Program and qualified as the first Level-4 system that fulfill national information technology classified protection, the “National Engineering Laboratory for the Safety Technology of Urban Rail Transit System” established in the company is the first special project for innovation in urban rail transit industry. The company completed the first demonstration project for millimeter wave in the high mobility environment of rail transit in our country. So, what is millimeter wave? 

Mr. Peng Hua, the senior vice president of Shenzhen YD Electronics, said: “Millimeter waves are the electromagnetic waves with wavelengths from ten to one millimeters, and corresponding to the radio frequencies of 30 to 300 gigahertz. The millimeter wave products were independently developed by our company, and the line-of-sight transmission distance can reach 10km, the transmission rate can reach 10G.”

Recently, the “Millimeter Wave Private Network Communication System for Rail Transit" jointly developed by Shenzhen YD Electronics and the Information Technology Institute of Southwest Jiaotong University has been successfully tested in the National Railway Test Base, and has achieved excellent test results, and this system realizes high-speed wireless train-to-ground communication in high mobility environment. Mr. Peng Hua further introduced the difficulties and the breakthroughs of this test.

Mr. Peng Hua introduced: “16 base stations were used in the test, and the train was installed with millimeter wave equipment, private wireless communication network was constructed for train-to-ground communication, it realized coverage for all kinds of railway scenarios, including ramps, curved track, tunnels, etc. The whole test environment was very hash and the railroad in the test field was very bumpy, this provided sufficient validation for our products, and proved the stability of our products. The slope of the railroad reaches 35/1000, and according to national high-speed railway standards, the turning radius needs to exceed 1km, in this test, the maximum turning radius reaches 1.426km. In this extremely harsh test environment, the peak rate of our communication system reaches 3G, and the normal communication rate is >2G, the latency is 0.2ms, and the handover time between base stations is 130μs, all the indicators are superior to the international 5G standard, the test results were verified by a third party.

“Based on the present, and looking into the future. Millimeter wave technology as one of key technologies of 5G, it deeply affects the development of industry-oriented applications in vertical industries.” Mr. Song Jing, the senior director of Shenzhen YD Electronics made a comprehensive analysis for the application prospect of millimeter wave communication in 5G rail transit vertical industry: “The private network communication system for rail transit based on millimeter wave technology will be widely applied in high-speed train, main line locomotive, and urban rail train, it can effectively solve the bottleneck problems of train-to-ground transmission in current big data operation scenarios, and provide reliable communication for obtaining the real-time status of train, line and network, and providing network access services for passengers. It provides strength reserve for China to seize the high-end international rail transit market in the 5G era, and provides guarantee for the strategic implementation of One Belt One Road, promotion of Chinese high-speed train to the world, intelligent manufacturing, and Sichuan-Tibet Railway construction.”

Technology innovation cannot be achieved without an excellent team. Shenzhen YD Electronics has a young technical team who is brave in innovation and breakthrough, and also has a group of leading experts who master the world's top technology. In the future, Shenzhen YD Electronics will continue to improve the quality of service, promote the application of innovative technology in the industry, and make contributions for building our country as a strong manufacturing country and strong network country. Network security guarantees national security, and consequently guarantees people’s safety. Shenzhen YD Electronics provides protection for you.
