This page describes how to set up a Citizens Broadband Radio Service Device (CBSD) configuration.
Before a new CBSD starts transmitting, it needs to register with Spectrum Access System (SAS) and send information about its physical installation such as the radio model, location, and antenna parameters.
Registration prerequisites
Some CBSDs only support multistep registration and therefore must be pre-configured in the Google SAS Portal or by using the Google SAS Portal API.
Single-step registration is when a Certified Professional Installer (CPI) provides device registration information to SAS in the registration request from the CBSD. For registration instructions that are specific to your CBSD, see your CBSD vendor documentation.
Only Federal Communications Commission (FCC)-approved CBSDs in compliance with FCC Part 96 can be registered with SAS. Most Category A and all Category B CBSDs require a CPI to verify the device's installation.
Category A CBSDs that meet at least one of the following conditions require a CPI validation:
- The CBSD does not automatically determine its location.
- The CBSD operates outdoors with an antenna height above average terrain (HAAT) of more than six meters. This type of CBSD must be registered as a Category B device.
Use multistep registration
The following sections describe how to use multistep registration to register a CBSD.
Configure installation parameters
To configure the installation parameters, follow these steps:
- Create a CBSD configuration by using the SAS Portal or the SAS Portal API.
- Import a CBSD by using the SAS Portal to create, sign, and update multiple CBSD configurations. For more information, see Import the CBSD configuration.
- Configure the installation parameters:
- Editors or admins only: On the right, enter the installation parameters.
- CPIs: Click Sign device directly or, to save as a draft, click Save.
Sign the installation parameters
To sign off on the installation parameters, you must be a CPI and have verified your CPI identity in the SAS Portal. To get CPI privileges, contact your administrator.
Register the CBSD to SAS
The steps to connect a CBSD with SAS might be different for each CBSD model. Check with your device vendor for documentation or instructions. Google SAS combines the information from the Google SAS Portal to process the registration request from the CBSD. If the registration request is successful, SAS responds with a CBSD ID. The CBSD is registered and can now request a grant.
If SAS rejects the registration request, it responds with an error message. The CBSD needs to correct the error and send another registration request.
The SAS portal rejects registration requests for any CBSD configurations that are already signed. You must enter CBSD parameters into the SAS Portal including the user ID, FCC ID, and the serial number.
Register your CBSD
You can register your CBSD by using the Google SAS Portal or, if you are using Baicells equipment, by using Baicells.
Use the SAS Portal
If you are using the SAS Portal to configure installation parameters, follow these steps:
- Enter the installation parameters for a CBSD configuration.
- Optional: If you aren't a CPI, click Save to save the draft of the CBSD configuration.
- Click Ready for CPI to indicate that you're finished with the configuration.
- After the CBSD configuration is signed by the CPI, a registration request can be sent from the device to Google SAS.
- If the registration request is successful, the CBSD is registered.
Use Baicells
If you are using Baicells equipment to configure installation parameters, follow these steps:
- Configure the CBSD in Baicells.
- Export the CBSD configuration from Baicells as a CSV file.
- To complete Step 1, configure the installation parameters and import this CSV file into the Google SAS Portal.
- To complete Step 2 of the multistep registration, go back to Baicells, select the CBSD, and then send the registration request.
