As the environment becomes more and more crowded in the RF realm, interference
has become a major issue. Far more than simply an occasional nuisance, this phenomenon
has the potential to seriously interrupt the conducting of business, personal communications,
hobbies and even critical life support monitoring systems. As a radio control model
hobbyist myself (see my
Airplanes And Rockets Website), I have been aware for 30 years about the perils
of interference and the profoundly disastrous results that can occur is left unchecked.
Preventing interference is a big part of the cure, since it is not always possible
to simply design a receiver that can reject the interference.
