  At the 2019 China Information and Communication Conference held a few days ago, Jingyang Cao, an expert from China Mobile Research Institute, said that after the 5G commercial license was issued, China Mobile announced that it would implement 5G commercial services in more than 50 cities by the end of the year. In 2020, the network coverage will be further expanded to provide 5G commercial services in all cities above the prefecture level. SA will become the target architecture of 5G network and will be commercially available to smartphone users and industry users in 2020.

5G已成为基站天面建设的主要驱动因素

  Jingyang Cao pointed out that 5G has become the main driving factor for the construction of base stations. For a period of time, 4G network traffic will continue to grow rapidly, but the follow-up will mainly rely on 5G reverse opening to meet the demand. In order to support the construction of 5G antennas, China Mobile has been increasing its efforts to integrate the sky and the earth in recent years. Multi-frequency antennas such as 4488 antenna and 4+4 antenna have been widely used. Correspondingly, the application of broadband non-electric antenna has been greatly reduced, and the process of antenna multi-frequency and electric adjustment has been significantly accelerated.

  The integration and replacement of the sky will be an important application mode of the subsequent traditional base station antenna. FPC supplie found that,A large number of single-frequency antennas, such as FAD smart antennas, in the existing network provide conditions for the integration of the sky and the earth. With the construction of NB/FDD, the 900/1800 frequency band has also rapidly formed its application scale. In addition, the integration strategy of the sky is closely related to the tower rent policy, and operators need to choose the optimal integration method based on the actual needs of the network.

  In the direction of 5G antenna demand, Jingyang Cao highlighted the following points:

More Frequency, Higher Convergence

  The D-band (2.6G) has been extended to 160MHz. At present, the industrial capability has been supported, and the antenna cost is basically unchanged or slightly increased. The new frequency band 4.9G can be used for capacity supplement, etc. When independent construction is not possible due to space constraints, it can be considered to be integrated with other AAU or passive antennas for deployment. AAU can be further integrated with traditional passive antennas, but how to meet the limitation of windward area and weight will face no small challenge. The existing sky surface will continue to be integrated, with the goal of building 5G without increasing the number of sky surfaces. For multi-frequency antennas such as 4488, it is necessary to improve the integration level and shorten the antenna length to facilitate engineering installation while maintaining the performance index.

More scenes, deeper coverage

  For urban areas that need both coverage and capacity, MassiveMIMO will be adopted in the initial stage, and its innovation direction is mainly to reduce weight and cost. Traditional multi-channel antennas can still be used for rural scenes with wide coverage and low capacity. For the newly-built high-speed rail, an 8-channel antenna can be introduced to solve the horizontal or vertical zero point problem through scanning capability. For roads, wide beam antennas can be used to improve line coverage by solving the vertical zero problem. For subway tunnels, leakage of cables, circumferential and wall-attached antennas can be considered to meet the capacity requirements.

More functions, more intelligence

  For macro station scenarios, AAU can support worker parameter measurement, creating conditions for intelligent network optimization. For large-scale public places and other indoor scenes, the antenna can be combined with Bluetooth technology to provide accurate positioning and IoT-related business capabilities while meeting the coverage requirements, thus meeting the development strategy of 5G+X. Jingyang Cao further pointed out that 5G high-performance indoor products are expensive at present, and operators can consider planning a series of station types to carry out fine indoor construction based on 4G construction experience and industrial reality.
