![]() ![]() The Open RAN represents a shift from traditional RAN architectures dominated by a small ecosystem toward a disaggregated, multi-vendor environment with modular elements, open interfaces, and programmable infrastructure. Strong relationships between RIC vendors and application vendors enhances rapid innovation propelled by an open ecosystem.The RIC’s ability to host RAN-centric applications enables new application vendors to enter the RAN market, bringing new innovation to CSPs.Disaggregation of management and control planes from the vRAN functions (basically handling the data plane) allows the RAN intelligence to be managed and controlled, more centrally, by a new entity introduced in the O-RAN standards called RAN Intelligent Controller (RIC), making the RAN programable.The multivendor environment encourages competition and innovation with best-of-breed solutions from different RAN vendors.The highly programmable infrastructure enables dynamic responses to fluctuating demand and eliminates inefficient use of spare capacity.vRAN also provides investment protection by allowing CSPs to run vRAN functions now and evolve to O-RAN using the same platform when O-RAN standards and technologies become mature.Additionally, vRAN delivers superior protection from security threats than the conventional parameter-based and reactive security approaches.vRAN enables consistent operability across various vRAN functions as well as network functions deployed throughout 5G networks, from the core, edge, to RAN.This increases performance, coverage and capacity without linearly scaling the entire RAN while improving the quality of experience (QoE). vRAN provides the ability to deploy various industry-leading vRAN functions at the best locations to serve their functional purposes, creating 5G networks with much more flexible design than the traditional RAN.
