Carrier Aggregation and the Road to Cognitive Radio and Superwide Spectrum

By | January 14, 2014

Often, the least hyped technologies are the most effective, get the widest adoption, and have the greatest impact. Carrier aggregation is one such technology that I don’t think it received its fair share of attention. LTE did bring a number of new features that were not available in 3G, such as MIMO. But MIMO was… Read More »

Should Small Cells Be Deployed In Their Own Spectrum Band?

By | April 9, 2013

Small cells raise a number of practical implementation questions which are yet to be resolved. One such question is whether small cells should operate in the same frequency band as the macrocell layer (co-channel deployment), or on a different frequency band. The question has profound implications to operators, vendors, and to regulators alike. To clarify,… Read More »

Unleashing the Power of HetNets: Interference Management Techniques for LTE-Advanced Networks

By | March 18, 2013

In my earlier blog post, The Hype & Reality of Small Cells Performance, I provided a qualitative review of small cell performance and discussed interference scenarios that limit performance. Perhaps the most defining problem of small cell deployments is the large transmit power imbalance between the macrocell and the small cell (~20-30 dB) which increases… Read More »
