CBRS Small Cell Radios
Instead of a LoRa antenna, Helium 5G Hotspots use Citizens Broadband Radio Service (CBRS) Radios to provide cellular coverage. CBRS is a wide broadcast 3.5Ghz band in the United States that does not require a 5G Hotspot Host to acquire spectrum licenses.
You can find more information about CBRS on the Federal Communications Commission Website
5G Hotspots can provide 5G cellular coverage when connected to Indoor or Outdoor CBRS Small Cell Radios while also providing LoRaWAN coverage.
Only certified CBRS Radios provisioned with the FreedomFi firmware will operate when connected to a 5G Hotspot.
CBRS Radios that are not certified and do not use the FreedomFi firmware will not provide 5G coverage and will not mine MOBILE.
The Helium Discord is the best place to get real-time support from the community. The #5g-cbrs channel is most relevant for using 5G on the Network.
Installation and Setup Guides
Instructions on installing a CBRS Small Cell Radio and registration with the SAS are provided by the individual 5G Hotspot Makers.
For FreedomFi Gateways, refer to the installation guides here:
For Bobcat500 Gateways, refer to the Bobcat Knowledge Center:
Misrepresentation of CBRS Radio installation information, including GPS location, height, antenna orientation, or other characteristics in a SAS, violates FCC regulations and may result in fines and possible criminal penalties.
Access Gateway and Radio Dashboards
Once the 5G Hotspot is onboarded and a Small Cell Radio installation is complete, the Small Cell Radio will automatically initialize and acquire a GPS lock. Once that is complete, the Small Cell Radio dashboard appears under the "Radio Dashboard" tab on the local IP address of the 5G Hotspot.
If you are using a FreedomFi gateway, you can access the miner and radio dashboard via the URL: http://freedomfi-gateway.local/
If you are using a Bobber 500 gateway, you can access the miner and radio dashboard via this URL: http://bobber-gateway.local/
5G Hotspot will appear on explorer.helium.com within five days, depending on how quickly it is registered in the SAS.
Outdoor Small Cell Radios
Outdoor Small Cell Radios are weatherized to endure the elements and are more powerful than Indoor Small Cell Radios. However, Outdoor Small Cell Radios create a larger area of 5G coverage while requiring more planning when installing and maintaining.
Outdoor Small Cell Radios require installation above ground level and require registration with the Spectrum Access System (SAS) to operate. Please evaluate your site location and ability to install these Small Cell Radios, and consider hiring a professional to ensure your installation is secure and meets all regulatory requirements.
SAS registration is expected to be completed within five days of submission. Hotspot Owners will be contacted via email with a confirmation of successful registration or with a rejection reply and an explanation of what needs to be corrected.
Indoor Small Cell Radios
Indoor Small Cell Radios are less powerful and are ideal for installations such as coffee shops, bars, grocery stores, etc. Indoor Small Cell Radios are generally easier to install and create a smaller, localized area of 5G coverage.
Indoor Small Cell Radios are physically smaller radios and can be installed at any height. Installing an Indoor Small Cell Radio outdoors is not recommended as they are not weather resistant.
Using Multiple Small Cell Radios
A single 5G Hotspot can support multiple Small Cell Radios but requires an additional network switch. A soft limit to consider is 7 Small Cell Radios to one 5G Hotspot; however, this limit is only theoretical as the real limiting factor is bandwidth saturation. All 5G Hotspots are built with a 1 Gbps Network Interface Card (NIC); the throughput of all the radios combined is limited to 1 Gbps or your internet speed, whichever is lower.
Confirm the Network is Working
Visit the FreedomFi Status page.
This status page will provide the latest updates on important issues that impact users, like Device Onboarding, SAS services, or other significant events.
Spectrum Access on the 5G Hotspot Dashboard
The Spectrum Access status will be in one of four states. It is not uncommon to see this status change frequently.
The Small Cell Radio has been granted Spectrum Access by the SAS and is providing 5G coverage.
The Spectrum Access was recently
None and is coming back online, this status should be transitory.
The Spectrum Access is disabled to the Small Cell Radio.
See below for more information.
The Spectrum Access Grant to the Small Cell Radio has Failed.
See below for more information.
A Dynamic Protection Area (DPA) is a geographic region where incumbents (Tier 1 users) get protection from PAL and GAA interference.
During a DPA Activation event, all Small Cell Radios in the given DPA Neighborhood are disabled by the SAS. There is nothing that you need or can do in these scenarios. The SAS will automatically re-grant Spectrum Access once the DPA Activation event has concluded.
A message similar to the following may also be present:
Spectrum Access status returned to "Connected" after it had been working. Wait and don't reboot. Suspension can last from hours to days for DPA Events. Contact support if you have been suspended for more than 48hrs. This is more prevalent if your location is within 150km of the DPA Regions.
This status is alarming, but do not let it scare you.
This "Failure" status is likely because the registration process has not been completed and submitted to the SAS for newly installed Small Cell Radios.
You may see an information pop-up similar to this:
SAS status code: 200 SAS response message: Response data: installationParam
Contact FreedomFi Support for any other warning messages.
DPA Neighborhood Regions
DPA regions can be viewed on the map below. Remember, these coordinates are not exact, and the affected areas for each DPA Activation event can reach as far as 150km inland.
Further information and maps of the DPA Neighborhoods in the United States and territories can be found here: CBRS Encumbrances Overview

Small Cell Radio GPS Requirement
All compatible CBRS Small Cell Radios use GPS for network timing data and to assert the Small Cell Radio's location when requesting approval to transmit from the FCC-regulated Spectrum Access System (SAS).
Small Cell Radios will need to be placed somewhere that allows the GPS antenna to be in a location with good GPS reception (i.e., near a window). Indoor Small Cell Radios are shipped with an external GPS antenna which can be positioned independently, while Outdoor Small Cell Radios have the GPS antenna integrated into the body directly.
