Network Overlays And The Capacity Crunch

Phillip Sorrells - 11-5-13--thumb Philip Sorrells July 8, 2011

As I mentioned in my last blog post, by my count there are around 575 potential combinations of tower components at a tower site. That is just the basic configuration of antenna and amplifier, cable and connectors, and a BTS. Now imagine a situation where cell sites are over-crowded, getting permits to build new ones is often challenging, and yet customers are clamoring for more and more bandwidth.

Sound familiar?

That’s the situation in many wireless markets these days. Network overlays are a common architectural solution for managing such circumstances. Capacity management is a top concern in almost every part of the RF network world where 3G and smart phones have collided. There is a nice white paper from Amdocs called 10 Ways to Deal with Mobile Data Capacity Crunch that outlines 10 approaches that seem to be on track to me. CommScope offers many of the infrastructure solutions that enable implementing such techniques.

In general, some of the best tools I know for managing complicated situations are simplification and elimination of variables. How can a cell site be built to reduce the number of variables, creating the higher probability of a “problem free” site turn on?

That’s a question that I am here to help you answer.

I am excited that our Site Solutions team is working on creative ideas for power management, remote site monitoring, cell tower fiber, and site sharing applications. I hope to share more about such solutions in the near future.

Until then, what do you think about the techniques outlined in the Amdocs document?
