The open radio access network (RAN) aims to bring openness and intelligence to the traditional closed and proprietary RAN technology and offer flexibility, performance improvement, and cost-efficiency in the RAN deployment and operation. This paper provides a comprehensive survey of the open RAN development. We briefly summarized the RAN evolution history and the state-of-the-art technologies applied in open RAN. The open RAN-related projects, activities, and standardization is then discussed.
