approved regulations on boosters that improve the strength of a signal to and from a handset. The FCC is concerned with the possibility of interference from souped-up signals. The new regulations now force the boosters to operate on the same band of spectrum it is boosting. With that in mind, all four major U.S. carriers, and some smaller operators, have agreed to share their spectrum if the booster manufacturers agree to protecting the carrier's networks. Many cellphone boosters already on the market can interfere with signals from other devices trying to reach network cell towers.
Some boosters can measure proximity to a cell tower and if too close to one, will reduce the gain or shut down. With safeguards in place, it was hoped by manufacturers of the devices that the FCC would not simply ban them. A statement from the FCC made it clear that the agency considers the boosters an intregal part of the wireless experience in areas where cell signals are weak.
As a result of the FCC's decision to set regulations on boosters, users will have to get permission from their carrier to use a booster, and will have to register the device with them.
