Antevia Networks, the telecoms equipment vendor changing the economics of 5G private networks, announced that it has successfully integrated with Nexus, the Neutral Host service gateway of Ontix, a leading UK Neutral Host operator. The achievement is a significant milestone in the companies’ collaboration to enable shared in-building 5G infrastructure using Multi-Operator Core Network (MOCN) technology to deliver Hybrid PMN and MNO services over a shared in-building RAN deployment.
During final testing, one device was connected to a private 5G core network, while a second device was connected to a public Mobile Network Operator (MNO) core network through the secure Ontix MOCN gateway. Both connections were carried over the same Antevia radio infrastructure.
The demonstration represents an important step towards a new model for Neutral Host In-Building (NHIB) connectivity in the UK, where a common radio layer can support both public mobile services and dedicated private 5G services.
It builds upon Antevia and Ontix’ partnership, announced in May 2026, to develop a solution using shared access spectrum in the n77 band, combining Antevia’s 5G RAN technology with Ontix’s Neutral Host Service Gateway, Nexus, and Service Enablement Model.
While traditional approaches to indoor mobile coverage require separate infrastructure for individual operators, private cellular networks are commonly deployed as another standalone system MOCN changes this model by allowing multiple networks to share a common radio infrastructure while maintaining connectivity to separate core networks.
For building owners, enterprises and venue operators, this creates the potential for one in-building 5G infrastructure investment to support multiple connectivity requirements. Meanwhile, for MNOs, the shared infrastructure model offers a route to improving indoor coverage without requiring a completely separate radio deployment for each operator.
“This is an important step from architecture to reality. We have now demonstrated a private 5G device and a public MNO device operating at the same time over a single Antevia RAN while connecting securely to two different core networks,” said Simon Cosgrove, CEO at Antevia Networks. “That is exactly what the MOCN model is intended to achieve. Rather than installing separate radio systems for public coverage and private enterprise services, we can use one shared radio layer and securely direct each subscriber to the appropriate network. Sharing infrastructure has the potential to fundamentally improve the economics of delivering high-quality 5G coverage inside buildings.”
“Our collaboration with Antevia is focused on making Neutral Host 5G simpler and more commercially viable for operators and building owners alike,” said Chris Newall, CEO at Ontix Ltd. “Successfully connecting public and private subscribers through the same RAN and into separate core networks via our secure MOCN gateway is a major step towards that goal. This architecture provides a practical foundation for venues, campuses and enterprises to combine high-quality public mobile coverage with private 5G services, without creating multiple overlapping infrastructure layers inside the same building.”
