1. Base station and terminal
The 5G network is a densely distributed base station network, and the base station distribution density is higher than that of previous generations of mobile systems.
Among them, the 28Ghz millimeter wave frequency band is used for communication between base station mobile terminals. The base station antenna system uses a phased array antenna system. The beam is cross-polarized in both vertical and horizontal directions to achieve higher user density and increase system user capacity.
The 5G terminal has the ability to the beginning to make it easy to optimize. In the current mobile phone terminal, the most suitable 5G antenna positions are at both ends, especially the upper end (near the earpiece position). Other 4G internal antennas must give way to them, which means that they have the right to preferential positions, and other antennas are moved elsewhere.
