The Key Bridge CBRS Sandbox

Key Bridge CBRS Sandbox is live: Try before you buy

We’re excited to announce the Key Bridge CBRS Sandbox — a full-featured, non-production environment that lets you explore, test, and evaluate the complete Key Bridge experience with zero billing and zero impact on live operations.

The concept is simple: everything in production, but no billing. It’s a genuine “try before you buy” environment built for developers, integrators, and operators who want to validate workflows, connect real CBSDs, and prove out integrations before committing to production.

Getting Started

1. Create your account
   Go to the Account portal:
   https://sandbox.keybridgewireless.com/user

2. Sign in to the Sandbox CBRS Portal
   Once your account is ready, log in here:
   https://sandbox.keybridgewireless.com/cbrs

3. Connect your devices to the Sandbox SAS
   Use the following Spectrum Access System endpoint in your CBSDs:

   https://sas9.cbrs.keybridgewireless.com:9191
   

   • Scheme: HTTPS
   • Port: 9191
   • Authentication: Normal client certificate authentication is required

   Full connection details and your User ID are available under CBRS Profile inside the portal.

What the Sandbox Gives You

• No billing — Evaluate the complete product experience without placing an order or incurring any charges.
• No volume or service limits — Use the portal and SAS freely for testing and evaluation.
• Full portal parity — The sandbox portal matches the production interface and workflows.
• Relaxed device security verifications — Security checks are intentionally eased to make testing and development easier.

What You Can Do

• Provision, test, and evaluate every portal function
• Connect real CBSDs to the sandbox SAS and observe registration, authorization, and ongoing operation
• Exercise bulk transfer, registration, and fleet-management workflows end-to-end

Critical Restriction

Do not use any sandbox information to start a real transmission.

Sandbox is strictly for testing and evaluation. Grants, authorizations, and all other sandbox outputs are not valid for live on-air operations.

How Sandbox Differs from Production

The sandbox SAS is best-effort only and deliberately isolated from production. It does not fully replicate the live environment:

Additional operational differences:

• CBRS 2.0 is disabled — Heartbeat duty cycle is fixed at 60 seconds
• Grant leases are shortened — Leases expire after 1 hour (shorter than production)
• Device security verifications are relaxed to support testing and development workflows

Other production-only behaviors may also differ. Treat the sandbox as a faithful functional preview of the portal and SAS experience, not a substitute for production spectrum operations.

In Short

Use the Key Bridge CBRS Sandbox to learn the portal, validate your integrations, and prove real-world workflows with actual CBSDs against a dedicated non-production SAS.

When you’re ready for live operations, simply switch to the production portal and production SAS.
