Orbi - why can't we change channels on satellites?
Wireless design best practice when installing multiple access points in an area is to have non-overlapping channels. So if you have 3 APs (RBR50, 2-RBS50) in an area, for 2.4 GHz, one AP would be cha...

Not entirely true. Max transmit power of wireless devices is strongly regulated, you can get FCC/CRTC fines if you exceed it. For the US, the 4x4 radio on the Orbi is transmitting at 1000mW or 30dbM, exactly the same power level as the 802.11n on the 2x2 radio.
Hm, pretty much convinced Orbi does use 802.11ac on the 2x2 radio, too. Of course it's regulated:
- Originally, U-NII Low (U-NII-1) was on 50 mW indoors only, current is 1 W power and max 4 W EIRP (max antenna gain 6 dB) for non-point-to-point.
- U-NII Mid (U-NII-2A) is max power 250 mW and max 1 W EIRP.
- U-NII Upper (U-NII-3) is max power 1 W and EIRP up to 200 W.
Further limitations apply without TPC.
Hope this clarifies why Netgear does use the high channel set for the wireless mesh.

And yet the power output on the 5G backhaul is the same as the 5G wifi channels: 36 dBm.
