O-RAN disaggregation brings a set of transformative advantages to any access technology in terms of scalability, flexibility, and vendor interoperability. The disaggregated architecture enables independent nodes to align with the nature of deployment resulting in a cost-effective high-performance network. The well-defined interfaces between the nodes with structured information elements, facilitate seamless AI integration for intelligent performance optimization, live diagnostics, energy efficiency and network resilience.

ATSC 3.0 and (B2X) access technologies are IP-native, and B2X aligns particularly well with O-RAN principles. This B2X solution would leverage the O-RAN ecosystem for optimized hardware with B2X software to customize the broadcast functionality. This paper highlights the benefits of disaggregating B2X infrastructure for broadcasting technologies in alignment with ORAN principles. The paper covers B2X description, Radio Access Network (RAN) architecture, RAN functional blocks, B2X eCPRI function split, B2X Radio types and broadcast specific network functionalities.

This paper proposes a flexible software-defined broadcast network that is future proof and scalable, with underlying hardware to support vendor-independent compatibility and maximize availability. This architecture promotes experimentation within limited geographics areas by modifying a few nodes without affecting the overall network performance.

B2X disaggregation aims to blend the technological advancement of the wireless infrastructure, with the simplicity and cost-effective nature of a broadcast network. Further information shall be presented to showcase the working and advantages of ORAN-aligned B2X technology.
