Spectrum is the most precious resource that a wireless operator has, and being able to pack more bits into a smaller chunk of spectrum, leads to the following benefits:
- More spectrum left over for future capacity expansion.
- In license exempt bands, more flexibility in finding clean spectrum.
- Lower co-channel interference in a multi-cell deployment, due to greater separation between cells using the same channels.
