Name – Job Role, Client Name

SCF's work program has been developed to support this new connectivity agenda, helping to promote and deliver the opportunities and overcome any barriers.

Neutral host requirements

Our work here aims to promote a better understanding of the role of neutral hosts, their relationship to MNOs and other service providers, and the advantages of this evolving service provision landscape in the delivery of digital transformation for governments, economies, enterprises and society at large.

5G products, splits and components

SCF is constantly evaluating products and splits against requirements to form a consensus view and concise definition of the types of 5G small cells and the key characteristics of the different types of commercially viable 5G small cell RAN products over the next five years.

FAPI specifications

FAPI is a central component of small cell specifications, responsible for open small cell products. SCF has pioneered these specifications and continues to evolve them to meet the needs of the industry, while keeping pace with the 3GPP specifications in the macro RAN area.

Network FAPI

Network-FAPI/Split6 are an extension of the FAPI specs, pioneered by SCF, to be applied in a network environment, such as disaggregated Split6 based small cell networks, consisting of Distributed Radio Units (S-RU), Distributed Lower-Baseband Units (S-DU) and Centralized Higher-Baseband Units (S- CU).

Private networks and edge

SCF is working to derive scalable models for lower complexity deployment scenarios – key areas of focus will be healthcare and manufacturing. Our work also looks at key policy issues including promoting better understanding of the role of private networks for cities and local authorities, as well as considering the role of roaming and spectrum allocation in the context of PCNs.

Advocacy and policy

SCF’s role extends to more than small cell technology and business cases, we also work with regulators, governments, and organizations. We act as advocates for small cells; on topics such as standardization, regulation, and health.

Our plan for 2023

  1. The right technology

    Driving standards that enable interoperability in the 5G era and support practical & effective open RAN implementation.

  2. Flexible business models

    Supporting an innovative and diverse service provider ecosystem.

  3. Scalable and repeatable deployment models

    Especially in the context of private networks.

  4. Fit-for-purpose regulation

    Lobbying for a more progressive and future-looking policy and regulatory landscape.
