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 »

Reaching The Limits of The Physical Layer: The Slow Shift To Enhancing Efficiency.

There is a general view that we are rapidly approaching the capacity limits of the physical layer. But as demand for capacity continues to grow, the supply of capacity is tapering off. What to do about this and how to continue to inject capacity is being addressed at standardization meetings. Let’s take a quick look at some of… Read More »
