1. Network modernization continues to be critical
LTE is the latest evolution of commercial cellular systems and boasts the greatest spectral efficiency yet. Efficiency improvements, however, are not limited to spectrum, but also to the ecosystem as a whole.
2. Cloud architectures will be debated and discussed
In the pursuit of efficiency, one of the biggest long-term benefits may come from cloud radio access network or network function virtualization, as it is also known.
3. Spectral re-use still matters
Efficiently improving spectrum usage is also key to a long-term, successful network. Capacity on a cellular network comes from the re-use of spectrum, not just its efficient use.
4. The metro layer matters more
Another way to add capacity and one that continues to gain popularity is the creation of a metro layer, new cells that are lower to the ground, placed not for initial coverage, but rather to add capacity to the system.
5. Indoor is increasingly important
When considering indoor coverage, this new layer of coverage adds massive capacity very close to the user and is under an enormous change in both architecture and efficiency.
6. Quality is the key to capacity
Simplification helps create network quality. As architectures have changed and evolved through the various generations, they have consistently been simplified.
