5G is commercially available, but because the goal of 5G network technology is to solve the problems of super-high capacity, low latency and large connection, there is no cost-effective advantage in network coverage and high-capacity scenarios. Moreover, the high-order 5G Massive MIMO base station system still has some shortcomings, such as large volume, high energy consumption, difficult site selection of new sites, high cost of network construction. Problems that are difficult to solve during the period. Therefore, in the next 5 to 8 years, the 4G network will still be the foundation, and the 5G network will be the superposition of the 4G network.

During this period, the best cost-effective solution for 5G network construction was in the ultra-high capacity and traffic layer. The outdoor Sub6 GHz will use 64 TR Massive MIMO antennas, and the indoor millimeter waves will also use Massive mimo antennas; in the middle and high capacity and overlay, The Sub 6GHz uses a 16 TR Massive MIMO antenna, an 8 TR Massive MImo antenna, and a 4G multi-system shared active/passive antenna. The indoor Sub 6 GHz uses an active/passive system.


The coexistence of 2G/3G/4G/5G network will also cause a series of Engineering difficulties. Base station location spectrum becomes scarce resources, and site selection is difficult; the load of tower infrastructure is difficult to support the increasing number, volume and weight of base station antennas. Based on the current situation of multi-network coexistence and multi-system integration, there is an urgent need for integrated, integrated, miniaturized active and passive antennas to solve these difficulties.

It is predicted that in the mainstream scenario, all non-5G requirements will be highly integrated into one antenna, and all 5G requirements will be highly integrated into the Gemini layout of the era of Jane's smart surface architecture; in special scenarios, all needs to be highly integrated into 1 antenna, forming the ALL-IN-ONE layout of the 5G era minimalist structure. In this sense, the antenna is an expert in network coverage, and scientific planning of the surface resources is an important part of network construction planning.


Driven by the dual factors of increased capacity and operating frequency band, the coverage radius of the cell will be significantly reduced, and the number of required base stations will be multiplied, so that the demand for the base station will be multiplied and the amount of active antenna used will increase. In the 5G era, the purchase amount of antennas used by operators has doubled. It is expected that the global annual purchase amount of antennas will exceed 20 billion US dollars during the peak period of 5G construction, which is four or five times that of current, bringing huge development opportunities to the mobile communication antenna industry.
