Are Wi-Fi Repeaters and Extenders Beneficial?

February 23, 2016

Subscribers today often supplement their existing Wi-Fi Access Points (AP) with wireless repeaters and extenders to enhance Wi-Fi coverage within the home network. Frequently, we are asked if these devices provide any real benefit. To answer these questions, we ran some tests in a house to measure and compare the relative performance of a couple […]

Coming Up for Air on LTE-U Coexistence: An Update

February 12, 2016

If you have been tracking CableLabs’ work to ensure that the introduction of LTE into unlicensed spectrum does not do disproportionate harm to Wi-Fi consumers, you may have noticed that it has been a while since we wrote in this blog on the topic. That’s not because we’ve moved on, however. To the contrary, we’ve […]

5G — The Beginning of an Exhilarating Journey

December 2, 2015

“5G” is the next step for the evolution of wireless technology beyond “4G-LTE” with the 2018 and 2020 Olympics acting as powerful Incentives for vendors to accelerate their product development. A few weeks ago, I travelled to San Francisco to chair a session at the new IEEE SDN-NFV conference and to participate in a panel […]

Fair LTE-U Coexistence Far From Proven In CableLabs / Qualcomm Testing

November 11, 2015

CableLabs has been working hard to ensure that the introduction of LTE into unlicensed spectrum is a win for wireless broadband, and that it does not disrupt the Wi-Fi services that consumers have come to rely on. We have covered in prior posts why that is a challenge, since LTE-U can take advantage of Wi-Fi’s […]

Wi-Fi vs. Duty Cycled LTE-U: In-Home Testing Reveals Coexistence Challenges

November 5, 2015

Rob Alderfer, VP Technology Policy, CableLabs and Nadia Yoza-Mitsuishi, Wireless Architect Intern, CableLabs also contributed to this article. In our last blog on Wi-Fi / LTE coexistence, we laid out the dangers attending the apparent decision of a few large carriers to go forward with the carrier scale deployment of a non-standard form of unlicensed […]

Can LTE-U Forum Specification Provide Fair Coexistence?

September 22, 2015

At CableLabs, we have been deeply engaged in ensuring that Wi-Fi and other technologies continue to thrive as LTE mobile technology is newly brought in to unlicensed spectrum. We have participated in the international standards process at 3GPP, and we are glad to say that there has been some progress by that body to lay […]

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’ […]
