Raspberry Pi 3B+ WiFi adapter Range

Wed Oct 09, 2019 6:52 pm

Hi Group,

I am curious if there is any data on this. I have a Pi that works fine indoors 20 feet away from WiFi as expected. I take the Pi outside maybe 100 feet away and it fails to catch a signal. What is the range the WiFi adapter can still hold/detect a signal? Is there a chart on performance by distance from access point?

I don't know official numbers.
Pi0W Wifi is likely less capable than that of Pi3B+.

I achieved 55m inhouse 38/70 link quality between Lolin ESP32 programmed via Arduino IDE and Pi Zero W:

Later in basement of IBM Böblingen lab I found that even 170m inhouse in line of sight with quality 30/70 are no problem!

Yes I notice in house I hardly if ever have issues. For some reason outdoors is not stable. I am starting to wonder if it could just be a power issue instead of a signal issue (since my phone outdoors records 2Mbps WiFi connection where the unit is).
