Are cellular repeaters legal?
Only in a stationary application can a wireless cellular repeater be used as the perfect solution to improve wireless coverage, but is it legal? Well, depending on where you are located in the world, most service providers request that you get their permission before you install a wireless repeater kit in your home or office since the frequency band your mobile phone or PC Card is operating on is licensed to that service provider by the applicable regulatory agency in that country, and therefore the service provider now has rights to that bandwidth. In the USA, that agency is called the Federal Communications Commission. (FCC) Now, whether that service provider decides to exercise that right against the end user is another matter. Most service providers overlook excerising this right unless they have determined the equipment you are using is causing interference to their network. In that case, they will track you down using test equipment to trace where the interference is coming from
