Cell Phone Signal Boosters

Signal boosters are devices that can help cell phone users improve their coverage in areas where they do not get good signals. For example, signal boosters can be placed in homes, small offices or even cars or commercial vehicles to provide increased signal strength for cell phones. As a result, users may complete calls in areas or places where they previously could not.

When these devices are properly installed, they can help consumers, businesses, 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, buildings and in rural areas.

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

On February 20, 2013, the Federal Communications Commission (FCC) issued Report and Order FCC 13-21 that stipulated new rules to improve wireless coverage through the use of signal boosters.

These new rules went into effect on March 1, 2014 for Industrial and Part 90 signal boosters and on April 30, 2014 for Consumer signal boosters. These rules require signal booster owners to:

  • Obtain wireless service provider consent to operate the device
  • Register the device with their serving wireless service provider prior to operation

These FAQs address the main questions regarding the new regulations. For up-to-date, accurate information regarding the regulations, visit the FCC's website at

Frequently Asked Questions

Consumer signal boosters are external devices that amplify cellular signals. These boosters enable individuals to improve wireless coverage within limited areas such as homes, cars, boats or RVs. These devices are designed to be installed and used "out of the box" – that is, without the operator having particular technical expertise or certification – and may be operated only with approved accessories as specified by the original signal booster manufacturer. (FCC 13-21, Paragraphs 13, 21, 46)

All FCC-approved signal boosters will have appropriate labeling.

The leading wireless services providers (Verizon Wireless, T-Mobile, Sprint, AT&T Mobility) and many rural cellular carriers that are members of the Rural Wireless Association (RWA) and the Competitive Carriers Association (CCA) have committed to provide blanket approval for signal boosters that meet the new protection standards. (FCC 13-21, Paragraph 25)

In the strictest sense, operators of all consumer signal boosters – whether new or existing, fixed or mobile – must obtain consent and register with their serving wireless service providers.

However, until a registration process is implemented by wireless service providers, existing signal booster operators can obtain consent from their serving wireless service providers in a variety of ways, such as by phone or email.

Upon being notified of the availability of the registration process, the operators must register signal boosters with their serving wireless service providers within 90 days. (FCC 13-21, Paragraphs 127-129)

Note that there is no requirement to replace existing signal boosters unless directed by the serving wireless service provider. In this instance, if a signal booster is found to be creating interference at a cell site, the operator may be directed by the serving wireless service provider or the FCC to turn off the signal booster and leave it off.

Operators of all consumer signal boosters that comply with the new performance specifications and are appropriately labeled need only to register with their serving wireless service providers.

No, there is no requirement to replace existing signal boosters with ones that have been approved under the new regulations.

However, the FCC has determined that the public interest will be best served by permitting consumers to operate existing signal boosters provided they (1) have the consent of their serving wireless service provider and (2) register their booster with that provider. (FCC 13-21, Paragraphs 127-129)

Wireless service providers are required to establish a free registration process by March 1, 2014, in accordance with FCC 13-21, Paragraphs 104-106.
Wireless service providers will communicate registration requirements to consumers at least 90 days before registration is required.

At a minimum, the operator will need to provide the following information:

  • Name of the consumer signal booster owner and/or operator, if different
  • Make, model and serial number of the device
  • Location of the device
  • Date of initial operation

It is possible that the warning label looks different than the sample label below. However, the warning label must include the same information (FCC 13-21, Paragraphs 115, 123) as follows:
