Interoperability testing helps you ensure that a Citizens Broadband Radio Service Device (CBSD) model
and its software version work well with Spectrum Access System (SAS). We recommend
that you, as a CBSD vendor, complete interoperability testing
on the test SAS environment before proceeding with the production
SAS environment.
Test and production SAS environments
The test environment is free to use. You can use the test environment for the
following types of testing:
CBSD interoperability
API integration
Simulated or pre-production deployments by customers, vendors, and integrators
To access the test environment, contactSAS Support.
The test environment does not moderate live traffic in the
Citizens Broadband Radio Service (CBRS) spectrum, but the production environment does.
However, the production environment is only available to SAS
customers.
The following table highlights thedifferencesbetween the test and production
SAS environments.
If SAS rejects your CPI credentials, then contact your TPA
to confirm that your credentials are valid and have been uploaded to the WInnForum
CPI database.
Grant authorization
Grants are authorized for test purposes only. Protected entities are
enforced based on the specifications for termination and
suspension zones in the test plan.
Entities such as simulated termination and suspension zones are
protected according to FCC regulations.
All entities are protected according to FCC regulations. However, grant requests
are rejected inside exclusion zones and might require grant adjustments or
suspensions.
DPAsare inactiveexceptfor Guam, Hawaii, and Puerto Rico.
They might be activated periodically and without notice to facilitate device
testing.
DPAs are activated based on incumbent activity detected byEnvironmental Sensing Capability (ESC)sensors.
In areas where ESC sensors are not deployed, DPAs remain active.
