Re: Still partying...
Yes. It's EIRP (I read the FCC Notice of Proposed Rulemaking in detail).
This band up to now is used by receive-only satellite earth stations. So the rules are written so that WISP's can use these frequencies, so long as they are not operating in the boresight of any of these earth stations. Since most of these are on the coasts, aimed at birds over the ocean, this isn't much of a restriction.
Yea, 3.7 Gig ain't great for NLOS, but for line of sight, 25W will go a long, long, way.
In order to use that much power, the sites must be fixed, and professionally installed. |

Excellent questions. As I mentioned there are still many questions to be answered. Fortunately, you're not alone in asking as similar questions are being asked within this thread with possible answers and speculation:

Of course, the FCC will ultimately have the final/official say but, fortunately, now they're definitely taking input from groups like WISPA.
HtH!

What hardware is available for this?
Are there band plans and channel assignments out for this already?
From the pdf... this part seems... amazing?
quote:
Fixed stations will be allowed to operate with a
peak power limit of 25 Watts per 25 megahertz bandwidth, and mobile stations with a peak power limit of
1 Watt per 25 megahertz bandwidth.
25 watts? I guess it's not the cook your eggs freq but this still seems a little excessive unless they are talking about the erp and not the measurement off the amp.
Also the "per 25 megahertz bandwidth" does that mean they are only assigning 2 channels or are they referring to something else?
