Hua Yanping and Liu Zhonghua, chief engineers of Hengxin Technology, were interviewed by C 1 14 at the 2020 China International Information and Communication Exhibition held recently. According to the two chief engineers, Hengxin Technology's 5G antennas, 5G leaky cables, high-performance connectors and other products have been widely used in the construction of 5G commercial networks, and pilot and scale applications have been carried out in 5G vertical applications and special scene coverage.
In the new era of 5G network construction, actively respond to the new demands of wireless terminals.
Hua Yanping introduced that the first phase of China's 5G network project was completed in 2020, and the second phase will be started on 202 1. The new 5G network construction period has put forward new requirements for the wireless terminal:
The first is 5G deep coverage, such as indoors, subways and tunnels. The demand for coverage will increase rapidly, and different indoor scenes need different solutions; The second is to further improve the 5G coverage in the core area, and at the same time achieve more coverage in suburbs and rural areas, giving full consideration to factors such as cost performance; Third, there will be more and more application requirements for 5G high, medium and low frequency hybrid networking, and more and more requirements for 5G and 4G converged networking; Fourth, vertical applications need more personalized and differentiated coverage solutions. For example, the car networking system needs ultra-high reliability, smart medical care needs ultra-high capacity and ultra-high speed, smart cities and smart ports need ultra-large connections, and smart factories need ultra-large connections and super anti-interference.
Liu Zhonghua said that Hengxin Technology has always believed that the deployment of 5G is selective and targeted, and it is carried out in the way of coexistence or combination of multiple schemes. Different deployment schemes will be applied for different coverage requirements of different scenarios.
In order to deepen the coverage of 5G networks, blind spots and hot spots will be the mainstream. Hengxin Technology has brought brand-new indoor 5G wireless coverage and tunnel 5G signal coverage products. For the 5G deployment of tunnel scene, Hengxin Technology independently developed 5G leaky cable with the same level and high-performance HPC leaky cable connector, and applied broadband leaky cable technology and leaky cable with the same level technology. With its characteristics of low loss, broadband and uniform field strength along the line, it provides a stable and reliable solution for the 5G signal coverage of tunnel scenes, and has been applied to the subway construction in major cities across the country.
In view of the miniaturization and integration requirements of 5G communication base stations and equipment, Hengxin Technology released HX 10 series, 2.2-5 series small connection components and MQ4/MQ5 series bundled components; Aiming at the problem of intermodulation stability caused by high frequency band, 5G connection components are brought to ensure intermodulation stability in the case of multi-system combination.
For the application of 5G vertical industry, Hengxin Technology launched the wireless access Internet of Things solution, and independently developed the leakage cable of the Internet of Things, which can achieve high-speed, stable and safe signal guarantee that antenna coverage cannot meet in specific scenarios. At present, it has been successfully applied to intelligent logistics sorting, integrated home and intelligent workshop construction, and will be deployed in intelligent warehousing, intelligent factories and automated ports in the future. In addition, special cable leakage products for mines have been developed for special industries such as coal mines, and passed the safety certification of mine products, providing assistance for the construction of smart mining areas.
Improve the product system and fully cover the wireless end of the communication network.
With the increasing popularity of 5G mobile phones, the demand for 5G signal coverage is more and more urgent in the indoor environment where 70% of the usage scenarios are used, and micro-base stations become the first choice. It is recognized in the industry that micro-base stations are an important way to solve the "last mile" of 5G network coverage. In addition to indoor sub-scenarios, 5G micro-base stations can also be used to solve the blind spots, hot spots and extended coverage of the network, especially the regional coverage of vertical applications. In the future, 5G micro-base stations will usher in hundreds of billions of application markets in smart cities, smart factories, intelligent transportation, smart port areas, smart mining areas, smart agriculture and other fields.
At present, there are many series of micro-base stations of Hengxin Technology, such as enterprise, distributed and home, which can meet the needs of different application scenarios. This series of products adopts innovative architecture design, which can connect hundreds of RUs and cover a wider area; The uplink noise can be effectively controlled, and the network performance is better; It has a forward bandwidth close to the user rate, and the transmission cost is low.
In addition, based on RIC smart network, Hengxin micro-base station automatically optimizes network parameters by using AI technology through network big data; You can flexibly merge and split cells to meet the needs of different scenarios; You can use star, chain, hybrid and other arbitrary ways to flexibly network, and provide energy-saving schemes based on scenarios.
Hua Yanping said that with the development of new service filters and micro-base station projects, the product line of Hengxin Technology has all covered the wireless end of the communication network. In the future, Hengxin will integrate existing RF products, antenna products and filters, as well as micro-base station technology, aim at 5G vertical applications, seek suitable positioning, and build a wireless access system in vertical applications.
As the focus of reform in the field of mobile communication and "new kinetic energy of economic development", 5G has become the key area of new infrastructure construction. Liu Zhonghua introduced that under the background of "new infrastructure", Hengxin Technology will continue to increase R&D investment, increase R&D efforts in products, technologies and solutions, do a good job in research reserves of 5G related technologies, and strive to provide products with excellent performance and quality and efficient and reliable solutions.
Hua Yanping further stated that in the face of the new development pattern proposed by the state, "the domestic big cycle is the main body, and the domestic and international double cycles promote each other", Hengxin Technology will focus on products in the field of 5G applications and products in the field of national defense and security, and contribute to the 5G construction in China.
