Open RAN Architectures Steadily Displace Proprietary Systems
Operators across major East Asian and North American markets are increasingly specifying Open RAN architectures positioned against legacy proprietary-only systems, responding to demand for multi-vendor flexibility that speeds network deployment without compromising interoperability across large coverage areas. This shift has required vendors to invest in interface engineering and interoperability validation capability, a process that can take eighteen to twenty-four months per architecture generation given required multi-vendor certification. Vendors are increasingly treating Open RAN specification as a competitive prerequisite for new network deployments, accelerating the transition well beyond proprietary retention. This shift is expected to strengthen further through 2027.
