Massive MIMO and beamforming technologies solve the interference limitations related to the densification of small cells by increasing the number of antennas at the site, allowing operators to optimize the radio frequency signal directed to the target user while minimizing the interference level to the remaining users.
Therefore, from a technical point of view, Massive MIMO and beamforming are the next most effective solutions in the capacity toolkit. In addition, more targeted beams are increasing the cell range of base stations, allowing operators to achieve equivalent 2GHz LTE coverage on higher mid-bands, thereby reducing the need to add more sites to compensate for higher operating frequency bands. The need for higher path loss.
