I have been following this technology since FCC first call for response. Here is the other side of the story:

For all I know, the result used by Google is mostly simulation based (NOT TRUE).<p>Qualcomm did their due diligence on simulations AND lab trials to show different results. IMHO, Qualcomm clearly has a better arguments.<p>Note that the link provided in the top comment by rupellohn is old. The latest one, referred in the news link, is probably (there are multiple filings) this one: <a href="http:&#x2F;&#x2F;apps.fcc.gov&#x2F;ecfs&#x2F;document&#x2F;view?id=60001331188" rel="nofollow">http:&#x2F;&#x2F;apps.fcc.gov&#x2F;ecfs&#x2F;document&#x2F;view?id=60001331188</a><p>Full list of recent filing here:

1. LTE-U has been proven to be a better neighbor to a WF AP than another WiFi AP. In other words, two WiFi APs in the same room perform worse than One WiFi AP and One LTE-U station.<p>2. Fairness: 2 WiFi APs should each share each have 5% airtime according to the standard, right? Wrong. Lab trials show one AP could take up to 80% +. Refer to <a href="http:&#x2F;&#x2F;apps.fcc.gov&#x2F;ecfs&#x2F;document&#x2F;view?id=60001104452" rel="nofollow">http:&#x2F;&#x2F;apps.fcc.gov&#x2F;ecfs&#x2F;document&#x2F;view?id=60001104452</a> &quot;Wi-Fi&#x2F;LTE-U Airtime Fairness&quot;. LTE-U always gives 50% Air time to its WiFi neighbor.<p>3. It is more of a political argument than a technological argument now. Note that at this point LTE-U spec does not violate the regulation on unlicensed spectrum.<p>DISCLAIMER: I don&#x27;t work for Qualcomm. But it is easy to see who has a better argument.
