Before a new CBSD can transmit, it needs to register with the SAS:
- The CBSD sends a registration request to the SAS containing information about its installation parameters, like the owner, location, and transmit characteristics.
- The SAS responds with a registration response.
If SAS approves the registration request, the SAS will respond with a CBSD ID. The CBSD is registered.
If the SAS rejects the registration request, it will respond with an error message. The CBSD needs to correct the error and send another registration request.
Register a CBSD that needs CPI validation
CBSDs that don’t require CPI validation can send a registration request directly to the SAS. However, most CBSDs require CPI validation:
- Category A CBSDs that meet any of the following conditions:
- Cannot automatically determine their location.
- Are operating outdoors with an antenna HAAT of more than 6 meters. The CBSD should be classified as a Category B device.
- All Category B CBSDs
There are 2 ways to register a CBSD that needs CPI installation:
- Single-step registration: The CPI provides the installation parameters of the CBSD, signed with their own CPI certificate, to the CBSD. Then, the CBSD sends a registration request to the SAS including the signed installation parameters in the
cpiSignatureDatafield. - Multi-step registration: The CPI uses the SAS Portal (or another user interface that’s integrated with the SAS Portal API) to send the installation parameters to the SAS. Then, the CBSD sends a registration request to the SAS without installation parameters.The SAS combines the information from the SAS Portal and the CBSD to process the registration request.
- Important: To register the CBSD, do not include the
installationParamfield in the registration request, even if the information matches exactly with the information the CPI provides.
- Important: To register the CBSD, do not include the
If the CPI uses a combination of single and multi-step registration procedures, it's important to know which information the SAS will use:
| CPI signed CBSD configuration exists in SAS Portal | No CPI signed CBSD configuration exists in SAS Portal | |
|---|---|---|
| cpiSignatureData sent by CBSD | cpiSignatureData information is used | cpiSignatureData information is used |
| No cpiSignatureData sent by CBSD | CBSD configuration in SAS Portal is used | Registration fails |
Data from 2 different sources will not merge. Whichever source is being used must be complete or the registration will fail.

Deregistration
If a CBSD needs to be decommissioned or simply moved, it will first send a deregistration request to the SAS. This indicates that the CBSD no longer wishes to be listed in the SAS with the parameters that it sent in its registration request.
If a CBSD needs to transmit again, the CBSD might send a registration request with updated parameters later.
