Open Radio Access Network (Open RAN)** #### **2. Open Radio Access Network (O-RAN) Alliance** #### **3. Open Source Projects RAN Transformation** ### **Summary** O-RAN (Open RAN) is a term used for industry-wide standards for RAN (Radio Access Network) interfaces that support interoperation between vendors’ equipment and offer network flexibility at a lower cost. The Open RAN standards aim to change the siloed nature of the RAN market, where a bunch of RAN vendors only offer equipment and software that is totally proprietary. This reduces flexibility and interoperability 5G Network Operation Modes are: * Non-Stand-Alone (NSA) Operation: Use 4G core network * Stand-Alone (NSA) Operation: Use 5G core network O-RAN Alliance was founded in February 2018 with the intention of promoting open and intelligent RAN. It was formed by a merger namely the C-RAN Alliance and the XRAN Forum. The C-RAN Alliance consisted of China Mobile and a lot of other Chinese vendors. On the other hand, the XRAN Forum consisted of US, European, Japanese and South Korean vendors and operators. AT&T, China Mobile, Deutsche Telekom, NTT Docomo and Orange were the initial founding operators. Benefits of O-RAN Architecture: * Reducing network CAPEX and OPEX * Improving network efficiency and performance * Importing new capability with great agility Challanges of Open Source Projects: * Keep pace with the standad * Latency and scalability issues * Limited contributions for RAN open source software * Lack of robust, deployable, and well-documented software * Need for secure open software software Open source projects by O-RAN Alliance and Linux Foundation: O-RAN Software Community (OSC) & O-RAN Specification Code Project (OSCP) ### Comment Technological developments like this can make greater progress, especially for users and providers. ## <center> **Discussion with team** </center> :::info ### 1.
