The recent announcement by the Wi-Fi Alliance of the new certification designation, Wi-Fi CERTIFIED Vantage™, is a significant step for the industry. It is the culmination of years of collaboration within the Wi-Fi ecosystem and the result of incorporating industry established Carrier Wi-Fi requirements into industry certified Wi-Fi devices. Wi-Fi Vantage devices will provide improved performance […]

Today is an important milestone for unlicensed spectrum coexistence – the Wi-Fi Alliance (WFA) has released its plan for testing how well LTE-Unlicensed coexists with Wi-Fi. This culminates many months of work by many expert engineers within the WFA and its membership, including CableLabs staff. The outcome is that we now have a definitive set […]

For the majority of homeowners, a single Wi-Fi Access Point (AP) is enough to provide whole home coverage with reliable performance. However, there are homes where a single AP provides insufficient coverage or has unreliable performance in certain areas of the home. For example, as the size of the house increases (> 3000 square feet), […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

“Operators of all kinds – fixed, mobile, converged and pure-play Wi-Fi – are moving beyond using Wi-Fi just for convenient access, or data offload, and are making it a central part of their broader strategies to support a high quality broadband experience everywhere.” (Excerpt from WBA Industry Report 2013: Global Trends in Public Wi-Fi p3) Over […]
