Can a Wi-Fi radio detect Duty Cycled LTE?
June 24, 2015
For my third blog I thought I’d give you preview of a side project I’ve been working on. The original question was pretty simple: Can I use a Wi-Fi radio to identify the presence of LTE? Before we go into what I’m finding, let’s recap: We know LTE is coming into the unlicensed spectrum in […]
Voice Service Over Wireless Networks
March 9, 2015
Voice traffic has consumed the airwaves of cellular and Wi-Fi networks for years now, being popular with subscribers and a revenue source for operators. Wi-Fi calling is rapidly expanding as a valued service for subscribers. Operators who offer Wi-Fi calling on their own Wi-Fi networks have a unique advantage to provide a superior Wi-Fi calling […]
Are all Wi-Fi Channels Created Equal?
January 22, 2015
Wi-Fi & RF Performance Over the years, Wi-Fi networks have evolved into planned, managed networks, delivering faster data rates and reliable service using outdoor Hotspots, Enterprise access points (AP), and Homespot gateways. As Wi-Fi Operators continue to rollout and expand Wi-Fi networks, ensuring reliable service and quality is a critical goal. ‘Carrier Grade Wi-Fi’ is […]
Wi-Fi vs. Duty Cycled LTE: A Balancing Act
December 3, 2014
In the second installment of my discussion on proposed LAA-LTE and Wi-Fi coexistence schemes, I am going to look at duty cycled solutions. Let’s recap: We know that this new technology for unlicensed spectrum will be available only to mobile operators since the mobile industry standards body (3GPP) has decided not to pursue the ‘standalone’ […]
Wi-Fi vs EU LBT: Houston, we have a problem
November 17, 2014
Licensed Assisted Access using LTE is the nascent LTE tech that puts cellular signals into the unlicensed spectrum. It goes by LAA-LTE or LTE-U for short. By all accounts the blitz is on to push this new tech into the field as fast as possible. NTT DoCoMo and Verizon have already announced their testing LTE-U. […]
Optimizing & Monetizing Wi-Fi Networks
October 23, 2014
The cable industry’s network has an opportunity to go beyond the home and enterprise to become a platform for a truly mobile service. Areas where CableLabs is focusing to optimize and standardize Cable Wi-Fi networks are discussed in my recent video interview with Alan Breznick of Light Reading. CableLabs’ role with expanding Wi-Fi network functionality […]
Community Wi-Fi – A Primer
September 11, 2014
When walking through a typical residential neighborhood today, all Wi-Fi access points in range are almost always locked, preventing access to anyone but the owner. Although subscribers pay for a certain high-speed broadband connection, bandwidth caps are not reached most of the time. An opportunity exists to optimize bandwidth resources for the benefit of the […]
In-home Wi-Fi Networks: Today, Tomorrow, and Beyond
July 22, 2014
Do you have broadband Internet service? If yes, most likely you also have a Wi-Fi Access Point (AP) for wireless connectivity in the home. Today, in-home Wi-Fi is almost ubiquitous in the countries with developed economies, and the penetration is only growing. A new iGR study forecasts that almost 98 percent of broadband data use […]
Will Wi-Fi Have to Share the Waves?
May 21, 2014
A New Competitor? Wi-Fi is alive and well and will be with us for a long time to come. But for the first time since it became the dominant wireless access technology, there is a potential competitor on the horizon. Few technologies today are as key to how we communicate as Wi-Fi. Worldwide about 50% […]
Approaches to Increasing Wireless Spectrum
May 13, 2014
At the 2014 Cable Show, one of the hottest topics was Wi-Fi. It doesn’t take long to realize how important access to this suddenly precious resource really is: Studies indicate that the number of wirelessly connected devices will triple by 2020, to a mind-blowing 30 billion devices. [Related: Wireless Spectrum Infographic] And with each new […]
