Hello everyone!
I will be attempting AQ static calibration in the coming days and need some help with determining the best location to gather the data. Wiki says that I need to avoid EM fields that change over time, so it's pretty clear that a microwave oven is not a good thing to stand next to AQ board when gathering data. Lack of vibration is pretty clear too.
What's not clear to me is weather things like WiFi or electric wires going inside the walls should be any concern. Can electric wires be considered an EM field changing over time? What I mean is - the EM field changes 50 times per second, but other than that it's pretty constant. What about WiFi? It's pretty hard to find a place without WiFi nowadays. I could switch off WiFi in my place while gathering calibration data, but I won;t be able to tell all my neighbors to do the same.
Another piece of info that could be useful is the fact that when I turn on a compass app in my phone in my apartment it doesn't really show the correct direction, mainly due to electric wires inside apartment walls and WiFi influence. The direction it shows is wrong, but it's always the same (the magnetometer inside the phone doesn't freak out).
Thanks in advance for any help regarding this topic!
