The FCC has released the long awaited new rules governing cellular amplification devices . You can read them here. Signal Boosters -
What is the main point of the new rules? That repeaters owned by private people now need to be approved and registered with their cellular provider?
Look under Manufacturers and you will see all the features the FCC expects to be built in to every amplifier . Rumor is they are releasing exact numbers to the manufacturers on March 1 . This has been brewing since November 2009 when they formed the committee to study all the issues with cellular amplifier . There are a lot of bad ones out there that totally screwed up networks and harm cellular other users . They then invited public comments for over 2 years . The bigger cellular amplifier companies spent millions of dollars on Lawyers and lobbyists to try and limit how far these new rules would go . Ultimately the carriers really had the final input as they pay the government billions and billions of dollars at auction to use the specific frequencies and asked for a lot more control over said frequencies. There is a lot of bad products out there , like all the offshore stuff people buy and Ebay and other sources . Ultimately the fail safes that are going to required in new amplifier will eliminate bad installations and such as the units are supposed to now shut themselves down when causing any problems to the frequencies
I look at it from the Amateur Radio perspective... These signal boosters must have those safety precautions in place because it needs to ensure that the signal won't bleed all over the frequency spectrum, what we in the Ham Radio world may call "inter-mod", that we sometimes hear on 2-meter repeaters. It can be annoying and irritating. If I were to obtain one of these, I would have no big issue registering the device, because like our 2-meter repeaters that must be registered... if someone's signal booster is causing interference, it needs to be shut down and the problem corrected, so that the offending unit won't irritate others. The only thing I can think of, for some not wanting to register their units, is because like some in the CB world... because they'll tweak their amplifiers so that they'd be heard all over the spectrum, some will find a way to tweak these boosters as well, just to be 'heard!'
