>>Also there has been a lot of usage of 2.4GHz devices in recent years.

bluetooth? - low power, doesn't travel far

wifi - been around long before 2005

cell phones - don't use 2.4 unless BT or wi-fi, have also been in the 1800/1900 gsm bands long before LTE/data networks

microwave ovens - been around forever.

Doesn't seem to add up.

not saying RF doesn't hurt, just playing devils advocate.
