Time for a Comprehensive Strategy for License-Exempt Spectrum

By | July 20, 2015

Calls for regulators to release more unlicensed spectrum for Wi-Fi are getting louder: the 2.4 GHz band is heavily used and the 5 GHz band suffers from many restrictions that limit its applicability. LTE’s entry into unlicensed spectrum is further amplifying these calls and adding an acute sense of urgency. But what is required is… Read More »

LTE Flavors in Unlicensed Spectrum

By | June 25, 2015

Guest post by Faris Alfarhan* The unprecedented increase in demand for high-speed broadband requires a bundle of solutions to satisfy the demanded capacity. Unlicensed spectrum is increasingly considered by cellular operators, internet service providers, and businesses as part of solution set. Unlicensed spectrum cannot match the quality of licensed spectrum, as the interference profile is… Read More »

Are Small Cells for 5G?

By | June 10, 2015

As the Small Cell Summit winds down I can’t help but wonder whether small cells are a technology awaiting 5G networks. There were many discussions on architecture at the conference which cannot but lead me to ask whether the market and technology drivers are in place for mass adoption. My reading of the situation points… Read More »

Cellular IoT Connectivity: Threats and Opportunities

By | April 20, 2015

There has been a flurry of activities related to wide-area Internet of Things (IoT) connectivity. The market recognizes that existing technologies, and more importantly business models and cost structures do not scale to meet IoT application requirements. A number of competing solutions have emerged and are today vying for commercial validation which scales through standardization.… Read More »

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

By | October 11, 2014

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… Read More »

From LTE-U to LTE-DSA: Solving The Capacity Crunch

By | March 31, 2014

The proposal by Qualcomm to enable LTE operation in unlicensed band (LTE-U) received a warm response from some (e.g. Ericsson, Verizon) and not so warm from others especially incumbents with strong legacy in Wi-Fi in both the vendor and operator communities. The contentious issue center on co-existence of LTE and Wi-Fi in the same band… Read More »

Observations on MWC 2014 – My Takeaways

By | February 28, 2014

In a nutshell, the wireless industry keeps on getting broader and more bifurcated. This is the main trend that has been around for years and that will not stop. Communication is becoming truly pervasive. Opportunities and confusion are intermingled. To understand it all, one needs to cut across wider breadth and dive into greater depth… Read More »

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 »

What the Future Bodes for Small Cells: An Operator Perspective

By | November 17, 2013

The 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… Read More »
