Summary
Open RAN is reshaping how mobile operators build radio access networks, replacing proprietary, single-vendor systems with disaggregated, interoperable components. Altiostar, now part of Rakuten Symphony following a billion-dollar acquisition, stands out as one of the sector's front runners, having built its open virtualized RAN software from a 2011 startup into a technology powering the world's first cloud-native commercial-scale mobile network in Japan.
Altiostar's product portfolio spans virtual centralised and distributed units, network management software, and system integration services designed to help operators cut total cost of ownership while retaining flexibility across macro cells, small cells, and massive MIMO configurations. Its expanding R&D footprint across the UK and India underpins a growing partner ecosystem built around 3GPP-compliant, multi-vendor RAN interoperability.
Deployments and trials with operators including Bharti Airtel, Dish Networks, Etisalat, Telefonica, and STC illustrate how Open RAN is moving from proof-of-concept into commercial rollout across multiple regions. Its trajectory offers a window into how vendor consolidation, spectrum strategy, and automation are converging to reshape the radio access network supply chain, and how a customer-centric approach built around regional hubs is helping open RAN vendors expand their footprint.
- Comprehensive product portfolio spanning vCU, vDU, and O-RU components
- Global deployment and trial footprint across Asia, Europe, the Middle East, and the Americas
