Problem
Deploying 5G and 4G radio access networks often relies on proprietary baseband hardware that ties carriers to a single vendor, inflates capital expenditures, and limits the ability to adopt emerging Open RAN specifications. This vendor lock‑in hampers network flexibility, slows rollout of new services, and increases operational complexity for operators seeking multi‑vendor solutions.
Solution
RANsemi delivers Open RAN‑compliant baseband System‑on‑Chips (SoCs) together with carrier‑grade software that implement the 7.2 split architecture for 5G and 4G radio access networks. The silicon integrates RF front‑end interfacing, digital baseband processing, and real‑time scheduling in a single low‑power die, reducing board‑level complexity and bill‑of‑materials costs. A modular software stack provides full protocol stack support, over‑the‑air (OTA) firmware upgrades, and seamless interoperability with O‑RAN Alliance‑certified components. By adhering to open standards, the solution enables operators and equipment vendors to mix and match hardware, accelerate network densification, and future‑proof deployments against evolving 3GPP releases. The offering is delivered as a turnkey package that can be integrated into macro, small‑cell, and edge‑compute platforms, supporting both greenfield builds and retrofit projects.
Target Audience
Primary customers are mobile network operators and telecom equipment manufacturers that require open, standards‑based baseband solutions for 5G and 4G radio access network deployments. The product also serves system integrators building private or enterprise RAN installations.
