It is well know that microwaves, bluetooth, cordless phones are the
major
interference sources in 2.4Ghz.
But what devices (with non WiFi standards) are using 5Ghz band used by
802.11n devices?
Specifically for 5180-5350, 5745-5805Mhz.
I checked the US spectrum allocation chart, there are some devices like
radar and satellite communication in the 5GHz bands.
Based on the comment of Cisco,
“It is generally true that fewer devices currently operating at 5 GHz
are
causing interference as compared to 2.4-GHz devices. But this will
change
over time. Just as everyone moved from 900 MHz to 2.4 GHz to avoid
interference, the “band jumping” effect will catch up with 5 GHz. Some
devices that already exist at 5 GHz include cordless phones, radar,
perimeter sensors, and digital satellite.”

There are a handful of point-to-point and point-to-multipoint devices
that exist that transmit at 5 GHz. How much of that is deployed, I
can’t say.
The FCC’s new Spectrum Dashboard is actually a nice tool for looking
into who owns licenses in different frequencies and for different
services in your area.
