To use CBRS (Citizens Broadband Radio Service), you need the following components:

1. CBRS Spectrum Access:

   • Access to the 3.5 GHz CBRS band, which operates under a shared, three-tier spectrum access system (SAS).
   • You can obtain a Priority Access License (PAL) or use it as a General Authorized Access (GAA) user if spectrum is available.

2. Spectrum Access System (SAS):

   • This cloud-based service coordinates spectrum use between different users. You'll need to register with an SAS provider to manage frequency allocations dynamically and avoid interference with higher-tier users (incumbents and PAL holders).

3. CBRS Devices (CBSDs):

   • CBSDs are the radios or base stations that transmit and receive signals in the CBRS band. These devices must be certified by the FCC and registered with the SAS for proper operation.

4. Core Network:

   • For enterprises or ISPs, you need a core network that can manage the CBRS network traffic. This can be either private or linked to a mobile carrier’s network.

5. CBRS-enabled End Devices:

   • Devices such as smartphones, IoT sensors, or routers need to support CBRS bands (band 48) to connect to the CBRS network.

6. Professional Installation (optional):

   • For some types of CBSDs, a certified professional may be required to install and configure the equipment according to FCC rules.
7. Backhaul:
   • A reliable backhaul connection, like fiber or satellite, is often needed to connect the CBRS system to the broader internet or a private network.

With these components, you can set up a CBRS-based wireless network for applications like private LTE/5G, IoT, or broadband internet.
