Previous discussion of a similar project, by [evidently] the same person: <a href="http:&#x2F;&#x2F;hforsten.com&#x2F;6-ghz-frequency-modulated-radar.html" rel="nofollow">http:&#x2F;&#x2F;hforsten.com&#x2F;6-ghz-frequency-modulated-radar.html</a><p>As before, this is totally awesome---until the FCC (or other national spectrum regulator) shows up at your door...<p>Here is an assortment of things that the author might be interfering with in the neighborhood of his 5.5 GHz carrier frequency: <a href="https:&#x2F;&#x2F;wirednot.wordpress.com&#x2F;2014&#x2F;01&#x2F;07&#x2F;what-else-is-in-the-5-ghz-spectrum-hint-its-not-just-weather-radar&#x2F;" rel="nofollow">https:&#x2F;&#x2F;wirednot.wordpress.com&#x2F;2014&#x2F;01&#x2F;07&#x2F;what-else-is-in-th...</a><p>Some of this is the sort of stuff you really don&#x27;t want to interfere with--both for safety reasons, and because of the likelihood of enforcement.<p>Next time I suggest that the author look into whether his jurisdiction will grant him an experimental license so he can do this legally. In many jurisdictions that is cheap and easy (unless, of course, you want to operate in a band where the interference risk is just too high).<p>Edit: I see the author is in Finland. Unfortunately for the author, I&#x27;m guessing this changes nothing since these frequencies are regulated both nationally and internationally. But it does mean that there is probably some local variation in the exact services that might be subject to interference. And who knows: maybe in Finland the 5.5 GHz band is a &quot;do whatever you want at any power level you want&quot; band. But I doubt it...
