Tech-Talk 01 : How ORAN is different from Traditional RAN | Traditional RAN Vs ORAN

Hi all, Go through our TechTalk which cover the difference between traditional and open RAN. Key Components and Benefits: Open Interfaces: ORAN defines standardized interfaces between different RAN functionalities, like the Radio Unit (RU), Distributed Unit (DU), and Centralized Unit (CU). This allows equipment from various vendors to seamlessly interact. Disaggregation: ORAN disaggregates the traditional RAN into distinct functional blocks, enabling operators to choose different vendors for each, further increasing flexibility and choice. Intelligence and Automation: ORAN incorporates functionalities like AI and machine learning to improve network performance, optimize resource allocation, automate tasks, and troubleshoot issues more efficiently. Virtualization: ORAN allows virtualization of RAN functions, enabling them to run on standard IT hardware instead of proprietary equipment, improving efficiency, scalability, and potentially reducing costs. Collaboration: The ORAN Alliance, a consortium of industry players, is actively developing and deploying ORAN specifications. Early Adoption: Major network operators and equipment vendors are already involved in ORAN adoption and experimentation. Transformational Potential: ORAN has the potential to fundamentally change the mobile network landscape by: Reducing costs for operators. Fostering the development of innovative solutions. Enabling more efficient and effective deployment of 5G and future generations of mobile networks. Challenges and Considerations: Maturity: ORAN is still in its early stages and evolving, requiring continued development and refinement. Complexity: Implementing and managing an open RAN network can be more complex compared to traditional closed systems. Security: Ensuring robust security in an open and multi-vendor environment is crucial. Traditional cellular base stations were monolithic units, combining hardware and software from a single vendor. To make networks more flexible and open, Open RAN splits these base station functions into three primary units: CU: Centralized Unit The “brain” of the network, responsible for higher layers of network management and communication. CU-CP (Control Plane): Handles signaling (RRC), data flow management on the control plane (part of PDCP protocol). CU-UP (User Plane): Handles user data traffic (user plane part of PDCP and the SDAP protocol). DU: Distributed Unit Typically located closer to the edge of the network, the DU handles real-time processing and lower-level communication protocols. Functions include: RLC (Radio Link Control), MAC (Medium Access Control), and High-PHY (higher levels of physical layer processing) RU: Radio Unit The radio “workhorse”, the RU deals with the actual transmission and reception of signals. Functions include: Low-PHY (lower levels of physical layer processing like FFT/iFFT operations, PRACH extraction), and the actual radio frequency (RF) processing of signals.
