With the rise of 4G network construction in the world, multi-network operation has become the main melody of the network development of operators. Qingdao Unicom's current network status is 2/3/4g coexistence. In the optimization and adjustment, the ideal situation is that 2/3/4G network can have its own independent antenna, so that RF adjustment is convenient and flexible. However, due to the constraints of antenna installation site resources, space shortage, construction cost and other factors, common antenna strategy can only be adopted in network construction in many cases, which not only saves resources, but also brings difficulties to RF adjustment and multi-network coordination optimization. In view of this situation, the Network Optimization Center of Qingdao Unicom combined with the actual situation of the network, made a statistical study of various common antennas, and made an analysis and adjustment plan according to the network demand. There are a large number of 2/3/4G common antenna sites in the current construction. According to statistics, the proportion of common antenna in the current network is over 60%, which is higher than the national average level. Three, the current total antenna situation classification 1. 2/4 g share a common antenna by 2/4 g RRU type of antenna and antenna panel. 2. 3/4G common antenna is divided into: the beautification antenna cannot be adjusted independently, the circuit board antenna cannot be adjusted independently, and the common antenna can be electrically adjusted independently. 3. 2/3/4/G common antenna is divided into: 2/3/4/G common antenna cannot be independently adjusted, and 2/3/4/G common antenna can be independently electrically adjusted. Four, common antenna formation reasons and advantages and disadvantages
