Raspberry Pi 3 B+ 5Ghz Onboard Wifi Interference?

[Ben]

Hey folks,

Any ideas if the 5ghz WiFi on the B+ would not cause interference?

I see there is a warning posted at the top of the page here warning about using the previous model (Pi 3) 2.4ghz onboard Wifi, I'm wondering if the 5ghz on the B+ would work around that issue?

Details:

I've got a Shake 4D kit with a Pi 3 B+ installed. :)

Cheers

Good morning.

We are also curious! We bought two a few days ago. When they arrive to Panamá, we will test.

Stay tuned :)

I don't know anything about these wifi chips. It is possible 5 GHz might have less impact if you were able to turn 2.4GHz completely off, can you? I'm sure you could reduce the impact if it was possible to reduce the transmit power, but most people would want the maximum possible range, so I don't know if they even offer a power output adjustment.

I've had some luck reducing RFI in the past (different project) putting a wifi dongle on the end of a 3-foot USB extension cable.

     It would be nice if an external aerial socket was provided on the R-Pi and there was 

the option of using some co-ax cable and a dipole aerial / directional array to get the RF 

signal away from the rest of the electronics. 

    Regards,

True, and a lot of people have mentioned that, but my understanding is that they would not have been able to do the FCC certification they did with an external connector.

If you need lower RF noise, it's probably better to move the entire transmitter circuit offboard anyway (eg. external USB-wifi dongle on a cable of suitable length).
