This report takes a deep dive into the virtualization and disaggregation of radio access networks and analyzes the various schools of thoughts ranging from basic virtualization of RAN functions (vRAN) to new open architectures such as open RAN, following the TIP initiative and the O-RAN Alliance specifications, designed to cut the dependency on proprietary RAN equipment supplied by the traditional vendors. The vRAN segment is taken from our existing RAN size and forecasts and broken down by 2G/3G/4G versus 5G, as well as by vCU/vDU and RU for each region, and also looks at the potential for indoor DAS replacement. The report covers a wide emerging ecosystem of vendors. Lastly, as more than 95% of open RAN deployments are vRAN, we call this market open vRAN.

TABLE OF CONTENTS
ABSTRACT
KEY TAKEAWAYS
IN 2023, THE OPEN RAN/VRAN MARKET STAYED FLAT YOY
- WHILE TRIALS, TESTING AND CERTIFICATION EFFORTS KEEP SWELLING, COMMERCIAL ROLLOUTS HAVE PAUSED
- We found that the focus shifted from open RAN to 5G SA
- DONE WITH DISH AND RAKUTEN MOBILE; RAKUTEN SYMPHONY'S PIPELINE DID NOT MATERIALIZE BUT 1&1 FINALLY DELIVERED!
- JAPAN CONTINUES TO SHOW THE WORLD WHAT AN OPEN RAN/VRAN ISLAND LOOKS LIKE
- Japan has propelled Fujitsu and NEC to the open RAN/vRAN leadership board...
- ...But in 2023, Samsung caught up and dethroned Fujitsu
- Samsung and Fujitsu are the top RU suppliers while Rakuten Symphony and Mavenir lead CU/DU
THE MARKET LULL EXTENDS FOR ANOTHER YEAR AND 2025 WILL BE THE TRIGGER YEAR, READY FOR TAKEOFF?
- 1Q24 FOLLOWS A STRONG 4Q23 FULL OF SUBSTANTIAL OPEN RAN PROJECTS
- WE DO NOT EXPECT AT&T ROLLOUT TO KICK IN BEFORE 4Q24
- 2025 WILL BE THE GLOBAL SWITCH YEAR
- The open vRAN penetration of the global traditional RAN sales is expected to hit 29% in 2029, up from 4.6% in 2024
- So far, Asia Pacific is the world's largest open vRAN market but the U.S. is awakening in a big way
- Among the countries ploughing money into open RAN, the U.S. is pushing for gLobal dominance
- Consequently, North America is poised to hit the 20% RAN sales penetration bar in 2025 and reach 58% by 2029
- We believe nearly all commercial open RAN networks will be running RAN functions on software
- vRAN and open RAN are 2 different configurations
- DISH and Rakuten Mobile bring cloud RAN to prime time
- As NTT docomo showed the world, an open RAN does not need to be virtual
WHILE THE OPEN VRAN RENAISSANCE BEGINS, THE SUSTAINABILITY OF THE ECOSYSTEM IS UNDER PRESSURE
- AS SOME OLD CHALLENGES REMAIN, THE NAYSAYERS STICK TO THEIR GUNS
- IN THE MEANTIME, A VAST OPEN RAN ECOSYSTEM KEEPS DEVELOPING, CONSOLIDATING AND RESTRUCTURING
- The early greenfield open RAN adopters embraced the multi-vendor approach...
- ...which is now under attack by the brownfield adopters and actors of this renaissance
- In this post 5G peak era, Tier 1 CSPs are locked in with abundant 5G footprints from Ericsson and Nokia
- At this stage, large Tier 1 CSPs seem inclined to do what AT&T is doing and lean heavily on a single big supplier for their open vRAN deployments
- Consequently, consolidation and restructuring are chugging along
- Lastly, the Japanese open RAN ecosystem is not immune either
- OREX: the creation of a Rakuten Symphony clone
- ALL OF THE ABOVE IS THE DIRECT CONSEQUENCE OF THE HUAWEI BAN
- For most of the world, the mission to ban the Chinese vendors is accomplished...
- ...And international cooperation is at its best
- This also drove the creation of a flurry of regional and national initiatives
OPEN VRAN IS A STRONG CANDIDATE FOR INDOOR USE CASES IN GENERAL AND AS A DAS REPLACEMENT IN PARTICULAR
- CURRENT C-RAN-BASED DAS ARCHITECTURES OFFER PLENTY OF OPPORTUNITIES FOR OPEN VRAN UPGRADES
- In 2026, the indoor open vRAN/open DAS market will surpass indoor DAS
- The neutral host capability has been protecting the DAS market so far but open vRAN can kill it all together
- Private wireless networks remain an open vRAN niche for now but 90% of large enterprise installations
- traditional RAN
- However, as DAS replacement shifts to smaller venues, open vRAN will eventually penetrate the SME space at some point
- Indoor 5G coverage is the vRAN driving force
- In this DAS bucket, JMA Wireless is unique
