Just a (final) word:
This is what I sent to Apple:
Please add more options in the advanced setting in the airport utility, like the possibility to adjust the transmit power. Best to add separately adjustment for the 2,4GHz and the 5GHZ band since the later has less coverage and may need a higher transmit power settings.
From the former Airport utility user guide:
"Security for AirPort Networks in Businesses and Classrooms:
Businesses and schools need to restrict network communications to authorized users
and keep data safe from prying eyes. To meet this need, Apple wireless devices and
software provide a robust suite of security mechanisms. Use AirPort Utility to set up
these advanced security features.
Transmitter Power Control:
Because radio waves travel in all directions, they can extend outside the confines of a
specific building. The Transmit Power setting in AirPort Utility lets you adjust the
transmission range of your device’s network. Only users within the network vicinity
have access to the network".
I think that Apple don't care much about security when they now has removed the possibility to adjust the transmitter power as well as other advanced settings.
And yes, I have no illusion that they will listen to me...
