The FCC adopted new rules for wireless signal boosters on February 20, 2013. These rules are described below, but do not go into full effect until March 1, 2014.
Read the Consumer Advisory for consumers who own signal boosters.


What are signal boosters?

Signal boosters are devices that can help cell phone users improve their coverage in areas where they do not get a good signal. For example, signal boosters can be placed in homes or cars to provide increased signal strength for cell phones, which may let the user complete a call in areas where they previously couldn’t. When these devices are properly installed, they can help consumers, wireless service providers, and public safety first responders by extending cell phone coverage to areas that would otherwise have weak signals such as tunnels, subways, inside buildings, and in rural areas.

Although signal boosters can improve cell phone coverage, malfunctioning, poorly designed, or improperly installed signal boosters can interfere with wireless networks and cause interference to a range of calls, including emergency and 911 calls.

Did the FCC recently adopt new rules for signal boosters?

Yes. The FCC recently adopted new rules to improve signal booster design so these devices won’t cause interference to wireless networks. The FCC also adopted new rules about what cell phone users need to do before using a signal booster.

I already have a signal booster; do I need to do anything?

If a wireless provider or the FCC asks you to turn off your signal booster because it is causing interference to a wireless network, you must turn off your booster and leave it off until the interference problem can be resolved. When the new rules go into effect, you will be able to purchase a booster with additional safeguards that protect wireless networks from interference.

I’d like to buy a signal booster today, what should I do?

Signal boosters with additional safeguards that meet the new rules are not available for sale yet. We expect new signal boosters will be available by the end of the 2013. Most wireless providers, including AT&T, Sprint, T–Mobile, and Verizon, have indicated they will authorize the use of these new signal boosters. New signal boosters will have this label:

It is possible that the warning label looks different than the sample label below. However, the warning label must include the same information.
Customer Label

Before you purchase a signal booster that does not have this label (or if you are unsure whether a particular model of signal booster will comply with the new rules), contact your wireless provider or the booster manufacturer. In addition, when your wireless provider develops a registration process, you must register your booster with your provider. There is no fee to register your booster.

Someone contacted me and said I have to shut down my booster because it’s causing interference. What should I do?

The FCC’s rules prohibit signal booster users from causing interference to wireless networks, even if the user has complied with all the other rules. If you are contacted by the FCC or any wireless provider – yours or any other – and told your signal booster is causing interference, you must shut it down until you can fix the interference problem.

The label on the booster says “E911 location information may not be provided or may be inaccurate for calls served by using this device.” What does that mean?

E911 systems automatically provide a 911 caller’s call back number to emergency service personnel and, in most cases, location information. When you use a signal booster to complete a call to 911, this location information may not be provided or may be inaccurate. This may affect the ability of emergency personnel to locate you if necessary. It is important to remember that signal boosters may help you complete calls, including calls to 911, in areas where you previously couldn’t. Each person should decide whether to use a signal booster given their individual circumstances.

It is possible that the warning label looks different than the sample label below. However, the warning label must include the same information.
Industrial Label

Can I purchase and use a signal booster with an “Industrial Use” label?

No. The FCC has established special rules for Consumer Signal Boosters to make sure they are simple to install and use, and won't harm wireless networks. Consumers should make sure they only purchase and use boosters with a Consumer Use label. Other boosters labeled for “Industrial Use” require special installation expertise and may only be used by FCC licensees or those given special permission.
