The boundaries between advanced 4G and early 5G are quite thin. Case in point: the shared spectrum Citizens Broadband Radio Service, originally created to support private and public services using Long Term Evolution 4G, is being adapted for 5G as well.
The CBRS Alliance says it will start work on new specifications that will support “OnGo” CBRS services using 5G. CBRS Alliance Release 3 will address support for 5G deployments using shared spectrum in the 3.5 GHz band.
The new specifications from the CBRS Alliance will complement 5G New Radio (5G NR), the new air interface developed by the 3rd Generation Partnership Project (3GPP) to support 5G.
Both indoor and outdoor use cases are envisioned, but fixed wireless could well emerge as the leading deployment case, despite the expected use to support indoor communications.
