Between DAS and Small Cells – A Practical Guide

Between DAS and Small CellsWhen small cells started appearing on the market, DAS was one of their targets. The thought was small cells would make DAS obsolete. After all, small cells are inexpensive and easy to deploy. This did not happen and not likely to happen for many reasons. DAS will be around as will small cells. While both serve similar functions, there are a few critical differences that ensure continuity for both types of technologies. Read more of this post


What the Future Bodes for Small Cells: An Operator Perspective

Small Cells New Order: Operator SurveyThe market awaits the arrival of outdoor small cells, but the wait continues. When small cell deployments will happen keeps sliding from one year to the next. I have always thought that some in the industry have been too optimistic on small cells deployment timelines and they have ignored important facts that define the deployment timelines and the shape they will take. In the last couple of months, I spent quite a bit of time looking at various aspects of small cells as part of two market reports that are now published talking in the process to a number of vendors and operators. In “Small Cells New Order” we surveyed leading operators on their plans for small cell deployments. What we found was clear indication that there will be no hockey stick curve yet for small cells. Instead, deployment will be organic and tactical to fill certain performance shortfalls. To put this in context, consider the following point: Read more of this post

Energy Consumption in Wireless Networks: The Big Picture

Green Energy

I recently came across a presentation on advanced antenna systems with the statement: “advanced antenna systems for power consumption savings not for capacity.” I was very intrigued for a couple of reasons. The first is how much of a problem is power consumption in wireless networks is. The second is that I recalled a conversation I had over 14 years ago with a colleague at Metawave prior to joining them. He said that they were approaching smart antenna systems from the perspective of capacity and not coverage. Back then, the nascent technology was traditionally targeted at improving coverage which was the reason why these systems failed to get traction in the market. So, today, we are changing the pitch for these systems from a capacity focus to a power savings focus. But will that make them more attractive? How much of a problem power consumption is?
