CBRS Deployment
CBRS (Citizens Broadband Radio Service) is a groundbreaking spectrum-sharing system in the US, enabling users to deploy 5G private networks using the 3,550-3,700MHz bandwidth. Unlike traditional spectrum management systems, which are either licensed or unlicensed, CBRS combines the advantages of both approaches while mitigating their drawbacks. It offers a simple and convenient process for users to access the bandwidth, similar to unlicensed bands, but with the added benefit of avoiding the risk of radio interference that is often associated with unlicensed spectrum. This unique approach makes CBRS an attractive option for deploying 5G private networks and supporting the growth of smart technologies, including AI and IoT applications.
To support CBRS deployment, the FCC has established stringent radio standards to minimize interference with neighboring bands. This promotes diverse network deployments and simultaneous application deployment within the CBRS band. Devices, including LIONS’ O-RU, must comply with FCC CBRS Part 96 requirements. LIONS’ O-RU has passed these tests, obtaining FCC certification for reliable and compliant 5G private network deployments.
Management
5G RAN serves as a network infrastructure supporting various applications. Therefore, it’s crucial for administrators to be able to configure and set up the RAN to meet the specific requirements of these applications.
CBRS features SAS (Spectrum Access System), a unique license-sharing management system. SAS simplifies spectrum application procedures while maintaining national spectrum control. RUs must communicate with SAS to ensure legal spectrum use and avoid interference. LIONS offers the SAS Domain Proxy program, enabling multiple O-RUs to communicate with SAS simultaneously. This program, validated by FCC Part 96, ensures compliance and facilitates legal spectrum access.
LIONS’ CBRS solution is tailored for 5G private networks. Built on ORAN RU foundations, it supports the n48 3,550-3,700MHz frequency band with an Open Fronthaul interface. It can interoperates with mainstream CUDUs and includes a Domain Proxy system for efficient SAS communication. LIONS’ solution is FCC certified for radio interference and SAS communication, ensuring compliance and reliability. Moreover, LIONS provides extensive support services, leveraging its experience in establishing CBRS 5G private networks for system integrators and branding customers.
Administrators can manage LIONS’ system through various methods:
● Element Management System (EMS): LIONS’ EMS enables administrators to monitor, configure, and control all LIONS products, including O-CU/O-DU, FHGW, and indoor/outdoor O-RU, through a web-based application running on the BBU server.
● O1 Configuration Management Interface: O1 serves as an O-RAN management interface for FCAPS management, Software management, and File management utilizing the NETCONF/YANG model. Users seeking an integrated management interface/dashboard or SMO (Service Management and Orchestration) can employ O1 to connect all elements of LIONS’ gNB components.
● M-Plane: In addition to the O1 interface, M-Plane represents another O-RAN interface for the management of O-RU and FHGW, in LIONS’ case using the NETCONF/YANG model. M-Plane can be utilized for the direct management of O-RU and FHGW, facilitating an integrated management interface/dashboard.
● Web Management: This tool supports direct management of O-RU and FHGW. Without specific applications, administrators can manage O-RU and FHGW via any web browser and IP address.
● RAN Intelligent Controller (RIC): LIONS supports RIC with O-RAN defined E2 and O1 interfaces.
