October, 2019: Branch Communications installs the first commercial OnGo (CBRS) wireless system in Oklahoma.

WHAT IS CBRS?

CBRS, short for Citizens Broadband Radio Service, is a new scheme developed by the FCC allowing shared commercial use of the 3550-3700MHz band (3.5GHz band). Commercially, CBRS technology solutions are being marketed as OnGo.

CBRS operates in a three tiered access and authorization framework: Incumbent, Priority Access License (PAL), and General Authorized Access (GAA). The access and operations are managed by an automated frequency coordinator, called a Spectrum Access System (SAS). More on Tiers

CBRS is technology-neutral and can be shared by multiple technologies at a single location. And CBRS networks bring LTE capabilities with Wi-Fi ease of deployment.

CBRS – 5G FOUNDATION

It is being said that 5G is the Cornerstone in building a “Connected World”. If that is the case, we believe that CBRS technology is a foundation that 5G will be built upon.

Branch Communications is at the forefront of CBRS technology and deployment. We have invested in-house expertise and forged early industry partnerships to provide effective solutions; from design thru installation.

WHAT CAN CBRS DO?

With wireless usage and mobile data demands growing continuously, current network architecture cannot keep up with these coverage and capacity demands. This is particularly true indoors.

Traditional Wi-Fi cannot keep up with these demands and current indoor solutions are both complex and expensive. This is where CBRS comes in to play. CBRS allows private LTE networks to be deployed that create a deep, wide connectivity fabric, in which multiple applications and services coexist side by side.

CBRS Tiers

Tier 1 – Incumbent Access

Incumbent Access users include authorized federal users in the 3550-3700 MHz band, Fixed Satellite Service (space-to-Earth) earth stations in the 3600-3650 MHz band, and, for a finite period, grandfathered wireless broadband licensees in the 3650-3700 MHz band.  Incumbent Access users receive protection against harmful interference from Priority Access Licensees and General Authorized Access users.

Tier 2 – Priority Access

The Priority Access tier consists of Priority Access Licenses (PALs) that will be licensed on a county-by-county basis. Each PAL consists of a 10 megahertz channel and up to seven PALs may be licensed in any given county, subject to a four PAL channel aggregation cap for any licensee. PALs must protect and accept interference from Incumbent Access users but receive protection from General Authorized Access users.

Tier 3
General Authorized Access (GAA)

The GAA tier is licensed-by-rule to permit open, flexible access to the band for the widest possible group of potential users. GAA users must not cause harmful interference to Incumbent Access users or Priority Access Licensees and must accept interference from these users. GAA users also have no expectation of interference protection from other GAA users.
