Re: [Discuss-gnuradio] What interference signals exist in 5Ghz ?

[Guanbo ZHENG]

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."

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.
