At this time, the two cells have The same frequency, but the AAS antennas use different downtilt angles, covering the near and far points respectively.
- the AAS antenna vertical splitting technology splits a cell into two cells, which doubles the spectrum resources, which may lead to capacity increase. At the same time, spectrum efficiency is likely to be greatly reduced due to the problem that the cell will increase interference and the potential power is halved (coverage degradation) after one minute. Therefore, if the crack is not properly selected, the capacity of the two cells after the splitting may not even reach the capacity of the original cell.
