Frequently Asked Questions (FAQ)

AT&T Cell Booster Pro is a device that acts as a miniature cell tower, and enables you to improve the quality of your organization’s indoor wireless service. If you have indoor wireless coverage that’s less than full strength, you can install a Cell Booster Pro device to help boost coverage.

If your agency is located in an area where AT&T provides cellular service, your indoor signal strength is two bars or less, and you are able to comply with all of the transport requirements outlined in the AT&T Cell Booster Pro User - Technical Requirements Guide, AT&T Cell Booster Pro may be the perfect solution for you. An AT&T Cell Booster Pro is designed for up to 64 simultaneous sessions and provides in-building coverage of up to 15,000 square feet per device, depending on building layout and construction. Up to 3 Cell Booster Pros can be used at a street address, bringing the total space to 45,000 square feet for up to 192 simultaneous sessions. An AT&T Cell Booster Pro may not be used as an RF source for a DAS.

The required bandwidth depends on the number of simultaneous users you want support and whether data-intensive applications will be used. The minimum required bandwidth recommended:

Cell Booster:

  • Broadband minimum downlink bandwidth - 5Mbps
  • Broadband minimum uplink bandwidth - 1Mbps

1 Cell Booster Pro:

  • Broadband minimum downlink bandwidth - 25Mbps
  • Broadband minimum uplink bandwidth - 5Mbps

2 Cell Booster Pros:

  • Broadband minimum downlink bandwidth - 30Mbps
  • Broadband minimum uplink bandwidth - 7Mbps

3 Cell Booster Pros

  • Broadband minimum downlink bandwidth - 35Mbps
  • Broadband Minimum uplink bandwidth - 9Mbps

Each AT&T Cell Booster Pro must have the GPS antenna attached so the device can lock location as required to support e911 emergency support teams.

The AT&T Cell Booster Pro creates a highly secure tunnel over an Internet connection back to the AT&T Core Network. You must comply with all the settings listed in the AT&T Cell Booster User – Technical Guide document for your device to activate and work properly.

  1. Download the AT&T Cell Booster app from your app store or go to Or scan the QR Code on your Cell Booster.

Yes, as long as it’s in an area where FirstNet is available.

Check Cell Booster service in your area.

Make sure you select FirstNet for your agency use to enable Band 14. If you choose AT&T by mistake, you should disconnect and reactivate your Cell Booster Pro, then select FirstNet.

Closed mode is one of two Cell Booster Pro device modes of operation (the other being Open mode). With Closed mode, only FirstNet wireless users specified on the User List can use the Cell Booster Pro device.

Phone numbers not on the User List will still attempt to connect to the Cell Booster Pro, but will not be able to access voice, data, or texting. These devices may appear to have no service, or service without access to the network. When these devices leave the area, airplane mode might need to be toggled for them to access the AT&T and FirstNet network. To prevent this from happening, set the Cell Booster Pro to Open mode.
