Open RAN is viewed as a game changer that could shift mobile radio access networks toward tailor‑made, architecture‑decomposed solutions, potentially altering deployment, supply chain, integration, and maintenance practices. The review aims to outline RAN evolution toward open models and highlight potential benefits and market trends. The authors examine ongoing proof‑of‑concept evaluations and theoretical studies conducted by academia and industry. Early O‑RAN deployments have already provided broadband services to end users.
Open RAN (radio access network) movement is perceived as a game changer, having robust potential to introduce shifts in mobile radio access networks towards tailor-made solutions based on the architecture decomposition. It is widely assumed that those changes will affect the approach to network deployments and supply chains of network elements and their further integration and maintenance. First deployments of O-RAN-based networks have already delivered broadband services to end users. In parallel, many proof-of-concept feature evaluations and theoretical studies are being conducted by academia and the industry. In this review, the authors describe the RAN evolution towards open models and make an attempt to indicate potential open RAN benefits and market trends.
