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

By | April 6, 2012

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… Read More »

Use Cases for the 2.5/2.6 GHz Spectrum: Macro or Micro/Pico Cells?

By | February 13, 2012

Should operators deploy a macro or micro cellular architecture in 2.5 GHz band? This is not a trivial question particularly for an incumbent wireless operator that already holds spectrum in lower spectrum bands. The same can be said of Greenfields looking to capitalize on the exponential demand for wireless data services.

Meeting IMT-Advanced Requirements: A Look Under the Hood of Next Generation Wireless Networks.

By | January 23, 2012

The International Telecommunication Union (ITU) has just approved LTE-Advanced and WiMAX-Advanced (aka WiMAX 2.0) as part of the IMT-Advanced standards. Aside of marketing catch phrases like “putting fiber optical speed on your mobile phone,” the statements about efficiency – being able to transfer higher data rates in lesser bandwidth – are what the industry will… Read More »

Use Cases for the 2.5/2.6 GHz Spectrum: Options for TDD Band 38

By | January 16, 2012

Large amounts of spectrum in the 2.5-2.7 GHz band are available now for mobile network deployments. Spectrum auctions in Europe in the past two years made much of the 190 MHz available to network operators. This band sold at a significant discount to the 800 MHz band (between 5 – 35x). While in the United States Clearwire used this band to deploy WiMAX, in Europe, operators are unanimous of LTE. So, what are the deployment options?
