Urban Site Densification

There are three methods to boost network capacity: adding spectrum, improving spectral efficiency, and deploying new sites. Spectrum addition has its drawbacks due to resource scarcity and high cost. Multi-channel and multi-sector are among the key technologies that play a crucial role in improving spectral efficiency. As traffic usage rapidly increases, it is necessary to improve spectral efficiency and deploy new sites to help boost overall site capacity.
