That's quite true. The RF pattern produced by a cell phone is
tailored primarily to meet SAR (specific absorption rate)
specifications. There's very little RF emitted in the direction of
the head, while much more out the back. Oddly, the peak for
smartphones is often straight down, where there are fewer obstructions
and the users hand is not likely to be holding the phone. Try
pointing the bottom of the phone at the nearest cell site and see if
the signal improves. It does on my Moto G phone.

The primary directions for mobile network antennas and WiFi antennas may
be different, so one would have to test them independently...

Lot's of influencing factors, that you want to take into consideration.

In this case, the issue is whether there is a difference in range and
performance (speed) between Apple wi-fi devices, and Android wi-fi
devices. This can be tested with both types of devices side-by-side

Side-by-side (taking this literally) might be yet another influencing
factor, where one device (might) severely interfere with the other.
Additionally (forgot to mention that in my previous post) there
shouldn't be anybody running around inside the test area (which is
larger than just the direct line of sight between the device(s) and the
AP), no cars should be passing in the vicinity, there should be no
neighboring WiFi networks even at the horizon, ...

and connecting to the same wireless router. I previously posted 2
good ways to perform the test, which so far nobody seems to have
performed. Also, nobody has asked me to perform any tests in order to
settle the issue, so I'm doing what I do best, which is nothing.

I won't do the tests, for several reasons:

- I don't have any Android device available, least several different ones.
- Where I live I can easily and at any time find several other WiFi
networks.
- I wouldn't have enough open range (without reflections from other
houses, passings cars, heck there are even electrified railroad tracks
at about 500m distance).
- ...

Way too bad conditions for performing such a test.

Best regards,
