Usually the equipment vendor will do the path calculations for you and
can tell you what's feasible for a given link. And they'll set you up
with a frequency coordinator who will find what channels are available.
6ghz not particularly harder.

What does it take to get licensed in 6 GHz? Is it more difficult to get
that license that it is 11 GHz?
Thank you,

In heavier rain zones, being able to use dishes as small as 3 ft in 6
GHz has been a game changer. Back when FCC minimum was 6 ft dish,
that was not feasible on many sites, due to structural issues or tower
rent. Rain fade much less of an issue at 6 GHz, but need to watch out
for multipath similar to 5 GHz.

What do you mean, not a chance at 18? If you can design for ACM and
rain fade, yes. I know the typical afmug purchase considers them too
pricey but there are lots of high quality, dual polarity 4' and 6'
size 18 GHz dishes.
I would not be excessively scared of 15 miles at 18 GHz with big
dishes.

huge dishes.
Play with Mimosa's designer, Cambium's LinkPlanner, etc.

Hi,
I've never yet done a licensed link and there is plenty of these two
frequencies available in my area. I need to be able to get 500Mbps at
about 15 miles. Is that possible with either of these?
What kind of real world speeds can I expect out of these and what
channel size do I need to license to get those speeds?
Is there something else I should consider? What brand/model radios
and dishes, what other frequencies for easier licensing, etc?
It would be great to be able to get a gig that distance, but I'm
trying to be realistic and get just what I really need to start with.
No legal advice please, just your experience with it and any
knowledge you'd be able/willing to share with the licensing of these
frequencies.
Thank you,
Brett A Mansfield
