An interesting example of Radio Frequency Interference.

I refer to a news report on CNN.com regarding a military radio frequency band are garage door openers.

Suddenly, the FCC Rules outlined on the backs of electronics mean a lot more to some people than they used to. Primarily the rule that states, “This device must accept any interference received, including interference that may cause undesired operation.”

So, what’s going on here? Basically, the garage door manufacturers took a gamble years ago and now they loose. The military reserved a band of frequencies with the FCC, meaning no one else could use the same frequencies unless they were extremely low power. Now that the military is using the frequency for whatever it is that they’re using it for, those transmissions are distorting the garage remote’s signal to the point that it’s unreadable by the garage door opener. A lot of these people are probably looking for someone to blame. The easy targets are the Marines and other military organizations that began using what they previously were not. They’re not at fault. They’re using a frequency band that they had reserved. It was the garage door companies that were getting away with being unlicensed for a short time. The gamble paid off for a while. It might pay off double too, since they might require that people pay them for upgrades for differing frequency band transmitter/receiver pairs. If it was me, I’d call up the company and complain like crazy until they fixed it for free.
