Turning the Page on 5G: Service Providers’ Vision for 6G

By | April 4, 2025

Service providers, vendors, cloud service providers, and other stakeholders gathered to define the vision, high-level requirements, and considerations for 6G networks during the 3GPP Workshop on 6G in Incheon, South Korea, from March 10–11, 2025. This Insight Note focuses on the most critical requirements voiced by service providers. While the views of other stakeholders are… Read More »

Will 5G Be Irrelevant?

By | May 25, 2015

Last week I had the privilege to discuss the latest wireless industry trends with colleagues at the RAN and Backhaul conference. We discussed 5G in addition to host of other topics ranging from architecture to virtualization and much in between: spectrum, Het Nets, IoT, etc. As I contemplate the proceedings, I came to wonder about… Read More »

How Small Cells Are Reshaping The Wireless Landscape

By | January 11, 2013

There’s much talk about small cells these days – on industry news sites, at conferences, in corporate announcements. This is not surprising given that mobile traffic doubles every year and, according to Cisco, will grow at a compound annual growth rate (CAGR) of 78 percent from 2011 to 2016. Wireless network architecture has relied greatly… Read More »

Small Cells and the Predictability Challenge

By | December 14, 2012

Anyone closely involved with small cells base station could not have failed to notice the contentious debate on backhaul capacity requirements. On the one hand, vendors of millimeter wave equipment advocate the need to support peak capacity figures, while on the other hand, vendors of other types of backhaul solution including point-to-multipoint systems point that… Read More »

In Focus: Interference in the 2.4 GHz ISM Band

By | October 23, 2012

In my previous blog entry, I set out to answer the question of how much WiFi is deployed. Here, I like to focus on the question of interference.  Unfortunately, I think there are fewer studies that characterize WiFi usage and interference than there ought to be. I will show here a few of the results… Read More »

How Much WiFi Is Out There?

By | October 9, 2012

The success of WiFi is nothing short of outstanding. Who would have thought that wireless network operators would adopt the technology and deploy WiFi access nodes in their tens of thousands to off-load their wide area networks? But with more carrier WiFi being rolled out in addition to your typical enterprise and personal access nodes,… Read More »

Under the Microscope: AT&T’s Nextwave Acquisition

By | August 13, 2012

In the most recent deal, AT&T filed to acquire Nextwave’s WCS (Wireless Communication Services) and AWS (Advanced Wireless Services) assets for $650 million. The bulk of this deal is about the WCS band, so what is this deal about and what does AT&T get for the money?

Aligning Mobile Services with Spectrum Properties: Information Showers

By | July 14, 2012

One essence of wireless communication does not change: the reliance on spectrum availability. The frequency spectrum is endowed with different features and characteristics that make trade-offs a necessity. One trade-off is that between data rate and mobility. The lower part of the frequency spectrum which is most amenable for mobile services due to economic reasons… Read More »

New Frontiers in Wireless Communications: Extremely High Frequency Communications.

By | July 1, 2012

The success of personal wireless communications may have been inevitable: communications is an essential tenant of human social structure. Coupled with the proliferation of wireless communication has been a drive to open up new bands of frequency spectrum. The most recent example is the millimeter wave band around 60 GHz which was assigned for unlicensed… Read More »

Evolution of the Air Interface: From 2G Through 4G and Beyond

By | May 3, 2012

Below is a link to a recent presentation I made to the local IEEE Ottawa Chapter and the Alliance of IEEE Consultants Network (AICN). I trace the evolution of the air interface of wireless systems from 2G (GSM, CDMA/IS95) through 3G and LTE to LTE-Advanced.

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 »
