Microcapacity: Unbinding Wireless Capacity Through Trading Exchanges

Microgeneration allows one to generate electricity for own use, typically using renewable resources such as wind or solar energy. Excess energy can be sold to the power company. The arrangement helps in evening out the variability in energy consumption. It reduces the peak load requirements for the main grid while energy generated during non-peak hours can be diverted… Read More »

It’s All Too Good To Keep Talking About The Capacity Problem

The capacity problem is at the heart of everything said about the wireless industry. Everybody loves to talk about this problem. To start, it is easy to give examples of exploding data consumption forecasts or quote numbers on mobile applications such as Facebook, Twitter , Instagram and many others. I suspect that the capacity problem makes for a… Read More »

Twisted Waves: A New Dimension in Wireless Communication – Part 1.

In some of my recent postings, I wrote about the limits of the physical layer and what that means for the future of wireless communications systems. Here, I like to mention new research that has promise of increasing the capacity of the physical layer. This new work is based on exploiting a property of electromagnetic waves heavily investigated… Read More »

Mobile Data Traffic Forecasts: A Comparative View

When it comes to planning radio access networks, mobile traffic data forecast become very important: Operators need to properly size their networks, and the ecosystem needs to predict potential bottlenecks and come up with creative solutions.

Dichotomy of Access and Backhaul Capacity Planning

I have listened to a few webinars recently by some of the major microwave backhaul vendors, all with the message that microwave has enough capacity to support required LTE data rates. It is evident that network operators have been pushing these vendors for higher data rates. Microwave after all cannot compete with fiber on capacity and MNOs (Mobile Network Operator) have been laying lots of fiber in anticipation of LTE network roll out.

LTE Data Rate: What Can We Expect?

I have already address peak LTE data rates and showed how they’re calculated. But what type of data rates would a user actually experience? This is what really matters from a quality of experience perspective.

LTE Peak Capacity Explained: How to Calculate it?

I like to focus on LTE capacity in the next few blog entries and present what can realistically be obtained. I have seen wild figures, mainly pushed by system vendors and consumed by many operators, journalist and writers who like to wow readers of the promise of new technologies. For network operators, erring on capacity expectations has negative consequences as capacity fundamentally impact the cost of the network both on the access side and the backhaul side. Inflated capacity figures would lead to under-dimensioning on the access side and over-dimensioning on the backhaul side.
