A Milestone in Wi-Fi / LTE-U Coexistence
September 21, 2016
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 […]
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 […]
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 […]
