What Capacity Problem?! A View on the Small Cell Market.

By | July 22, 2016

Small cells have existed and been talked about for about a decade now. The technology and market went through different phases tracking 3G, LTE and now 5G technologies. Yet, the deployment of small cells has been timid and numbers fall below expectations. The fundamental thesis behind small cells is that demand for capacity exceeds supply. The… Read More »

Edging Closer Towards Disruption in Radio Access Networks

By | August 31, 2015

In past articles [1, 2], I stressed that Cloud RAN is a disruptive technology. There are a few reasons for this, but I think that most critical reason is that Cloud RAN breaks open a pricing structure that’s been in use ever since the wireless industry was created. The current pricing model for base stations is… 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 »

Small Cells Progress Report – Challenges and Opportunities.

By | June 6, 2014

I have just released a new research report on the progress of small cell deployments in collaboration with ExelixistNet:  “Small Cell Ecosystem: Challenges and Opportunities.” The report examines mobile operators’ plans and deployment strategies of small cells and backhaul solutions along with vendor and technology preferences. The research is based on experience gathered by operators… Read More »

Further Enhanced ICIC (FeICIC)

By | May 7, 2014

Guest post by Faris Alfarhan* In an earlier post, R10-LTE enhanced inter-cell interference coordination (eICIC) techniques for heterogeneous networks were discussed, along with the concept of small cell range expansion. The purpose of cell range expansion is to offload more traffic from macro cells to small cells and hence achieve larger cell splitting gains. By… Read More »

Trends in Wireless Network Densification

By | April 28, 2014

One of the main trends in radio access network (RAN) is the bifurcation of systems that enable network densification. Today, mobile network operators have more options than ever before for the means of providing service to their subscribers. Alongside the evolution of wireless standards to provide higher spectral efficiency, vendors have unleashed a wide variety… 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 »

The Coming of Cloud RAN

By | January 6, 2014

The evolution of wireless communications has spawned many innovations but the cellular concept where base stations are dispersed to meet coverage and capacity requirements remains constant. This is about to change, sort of, if Cloud Radio Access Network (CRAN) architecture lives up to its vision. What makes CRAN such an interesting development is that it… 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 »

LTE-Advanced, 3.5 GHz, Small Cells and Neutral Host Services: A Powerful Mix to Abundantly Increase Network Capacity

By | September 16, 2013

At a recent GTI event in Japan, Huawei demonstrated 770 Mbps peak throughput in a market trial of LTE-Advanced in 3.5 GHz spectrum. This was achieved with TD-LTE access mode with carrier aggregation. The trial showed 500 Mbps average throughput over multiple sites. Furthermore, Softbank demonstrated the ability to provide 1.2 Gbps peak throughput using… Read More »
