Interesting. Especially since the older microwave ovens operated on 800
and
900 Mhz.


I think the confusion here comes from certain articles.

while 900 mhz was considered microwaves, hence the name "microwave ovens" when
they were invented,

most of the articles I read that mentioned the microwave band starting at
around 1 ghz actually say thst microwaves "start at around 1 ghz",

instead of saying that they do start around 1 ghz.

I consider 900 mhz to be "around" 1 ghz.

I think that a lot of people took the word "around" to mean "does".

and then they might have even printed up websites theirselves that say they do
start at 1 ghz.
