I love this wording:  "strong evidence (i.e. from spectrum monitoring) that
shows that the current use of WiFi in this band is causing serious
interference into the other services"

I would be tempted to re-phrase this to more accurately say that there is
"strong evidence that show that the current use of WiFi in this band is
causing serious connectivity and also causing serious 'interference' with
the comfortable oligopoly enjoyed by incumbent operators"

Clearly it should be stopped.  Seriously.
:-P
