Smart Radio for 3.5 GHz CBRS band is compliant to FCC Part 96 regulatory requirements. The RM-3625 CBRS Smart Radio provides all the building blocks to deploy high performance and cost effective private broadband networks. The dual role CBSD (Gateway) + EUD (transparent bridge) is available in use-case optimized form factors. The Smart Radio embeds Doodle Labs CBRS with Mesh Rider technology.
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.The device category CBSD-A is defined for urban use cases and high powered CBSD-B for rural-outdoor settings will be introduced in the future.
The FCC has authorized over 10 companies to operate the SAS. Doodle Labs has worked closely with Federated Wireless to ensure the interoperability of it’s CBSD-A and pre-configure it to make this a turn-key operation. Once the CBSD receives the authorization from the SAS, it can then instruct the downstream EUD (End User Device) to begin the operation.
The RM-3625 CBRS Band Smart Radio is an innovative dual role device. It can be software configured for either the CBSD-A role or the EUD role to simplify the network planning. The RM-3625 is available in various form factors to meet various stringent project requirements. The table below provides quick overview of the technical specifications.
