“Radio access network (RAN) equipment refers to equipment in a wireless telecommunications system that provides the wireless access link with the customer handset (e.g., smartphones), and also manages radio resources,” Metzler explains in the report’s introduction. “The high levels of concentration in the RAN supplier market led network operators in multiple regions around the world to investigate Open RAN as a means of nurturing alternatives to current suppliers.”
Metzler’s paper on Open RAN was inspired in part by the April 2023 release of the National Security Council’s “Principles for 6G,” which stated that the 6G standard should be “open and resilient by design.” Additionally, Metzler observed that the 5G standard had reached widespread adoption (suggesting that 6G would be forthcoming), the U.S. Government was promoting broadband access and increasing RAN supplier diversity, and the National Telecommunications and Information Agency published an Open RAN Security Report. “In aggregate, these developments indicated that a robust assessment of Open RAN was timely— for network operators, for policymakers, and for network equipment suppliers themselves,” Metzler writes.
