CBRS (Citizen’s Broadband Radio Service) is a very large swath of license free 3.5 GHz spectrum newly released by FCC to promote the development of new applications. The FCC calls it an “Innovation band” with the intention that it will ignite the development of new use cases, like what WiFi did over 20 years ago. Because CBRS band’s shared access is managed, it provides interference protection.
Smart Radio provides resilient, low latency, long-range, high-throughput link to implement industrial-grade private wireless mobile mesh Networks in license free band.
Doodle Labs has extended it’s patented Mesh Rider technology to leverage its capabilities in the license free CBRS band. The Smart Radio enables organizations to deploy license free private wireless as easily as WiFi. For more information, please visit Smart Radio home page.
Fully certified with all regulatory certifications
The Smart Radios are per-certified to work with Google SAS and Federated Wireless SAS to make this a truly plug-and-play operation.
Supports both General Access and Priority Access licenses
Full portfolio of Short Range (CBSD-A), Rural Gateways (CBSD-B) and End User Devices (EUD)
The figure shows the Point to Multi-Point Network architecture for the license free CBRS band. At power up, every CBSD (Citizens Broadband Radio Service Device) is required to contact the shared Spectrum Access System (SAS) over the Internet and receive the operating parameters like channel and the RF power limit. The SAS provides this authorization in accordance with other CBSDs operating in the area. Once the CBSD receives the authorization from the SAS, it can then instruct the downstream EUD (End User Device) to begin the operation.
Doodle Labs has the complete portfolio of CBSD-A (self-installable) for urban use cases, high powered CBSD-B (professional installation) for rural-outdoor settings. Additionally the corresponding EUDs are available.
The CBRS topology is modeled after the cellular architecture. The SAS assigns non-overlapping/non-interfering channels to the adjacent cells. This greatly increase the ability to deploy large private networks without the worry of interference.

After almost 5 years of planning, the commercial CBRS deployments have just begun in Q1 2020. The industry is excited to take advantage of the opportunities presented by such a large swath of unlicensed spectrum becoming available (For reference, CBRS is 150 MHz while 2.4 GHz WiFi is only 70 MHz wide band). There are many things to learn and many experiences to share. Here we have curated some resources that we think may be useful in your research.
