Summary
Telecom networks are undergoing a structural shift from traditional radio access network hardware toward fully virtualised infrastructure, opening new possibilities for service creation, automation and cost transformation that legacy architectures could never support. This transition is reshaping how operators think about capital investment, vendor relationships and the pace at which they can launch new services.
A Japanese conglomerate with roots in e-commerce, digital infrastructure and technology entered the mobile market as a greenfield operator, building a network that is virtualised end to end, from the radio access layer through to the core, with automation embedded across both network functions and service delivery. Competing directly against long-established incumbents, the operator's approach has become a widely discussed case study in what a mobile network built without legacy constraints can achieve.
A significant acquisition in the Open RAN space, combined with the creation of a dedicated symphony of network software and services, has positioned the operator as a serious contender in the broader movement toward open, interoperable radio access networks. The strategy signals how disaggregated, software-driven network architecture is becoming a genuine alternative to traditional single-vendor deployments across the telecom industry.
Can a fully virtualised, greenfield network architecture outpace what decades-old incumbent infrastructure was built to deliver?
