China's 5G construction is in the leading position in the world. In the distribution of 5G industrial chain, wireless main equipment and transmission equipment occupy most of the value of the industrial chain. However, the threshold of network planning and design is high, and private design institutes need to be upgraded. In terms of wireless main equipment, antennas and PCBs are rising in volume and price, and the demand for small base stations is exploding. At the same time, 5G construction will continue to benefit transmission network equipment.
