On the one hand, the number of 5G base stations in China has increased significantly. 5G communication spectrum is mainly distributed in high frequency bands. The higher the frequency, the faster the signal attenuation, and the smaller the coverage area at the same power.
In the 2G, 3G and 4G era, the spectrum of China's three major operators is mainly distributed below 2.6GHz, and the spectrum of China Unicom and mobile in the 5G stage is in the 3.4-3.6GHz range. With the increase of frequency, the number of 5G base stations will increase significantly and is expected to reach twice the number of 4G base stations.
On the other hand, the demand for 5G also brings the technological upgrade of connectors. Under the characteristics of 5G low-latency and high-bandwidth transmission, the data transmission volume has been greatly improved, and the traffic density of 5G has been increased to 100 times that of 4G. With the miniaturization and integration of 5G base stations, the space occupied by the connector is further increased. Compression, electromagnetic interference and heat dissipation have also become important issues.
Therefore, 5G has higher requirements for the density, transmission rate, heat dissipation, electromagnetic interference resistance and reliability of the connector, and the value of the connector has been further improved.
With the increase in the number of base stations and the increase in technical requirements, the connector market is expected to grow significantly and enter a high-boom cycle.
According to the forecast of the Ministry of Industry and Information Technology of China, domestic operators' investment in 5G will be 1.5 times that of 4G, and the total investment will reach 1.5 trillion yuan. As for the pace of demand, with the start of 5G construction in 2019, the scale of 5G base station construction will also grow rapidly.
Military connector manufacturers have deep technical accumulation and strong competitiveness, which will fully benefit from the growing demand for connectors in the communications field.
