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.
