This course made for Telecom professional to understand about ORAN Concept and how it can implemented in latest and existing technology. Here we discuss about difference with virtualization and its openness which impact customer for deployments CAPEX/OPEX .Here it also describe about some vendors who provides services for all deployments. Since this is the very basic training for beginners and providing information related to the virtualization and Openness and later stage in future module for each and every working groups of OpenRAN. Later stage we can also discuss about the TIP and some real time examples here we discuss about the OpenRAN benefits and implementation used for the 5G. Open Radio Access Networks, or Open RAN, refers to a disaggregated approach to deploying mobile networks by using open and interoperable protocols and interfaces, which allows for increased flexibility over traditional RAN systems. Open RAN can be implemented with vendor-neutral hardware and software-defined technology based on open interfaces and industry-developed standards. In a traditional RAN system, the radio, hardware and software are proprietary. This means that nearly all of the equipment comes from one supplier and that operators are unable to, for example, deploy a network using radios from one vendor with hardware and software from another vendor. Mixing and matching cell sites from different providers typically leads to a performance reduction. The result is that most network operators, while supporting multiple RAN vendors, will deploy networks using a single vendor in a geographic region. This can create vendor lock-in with high barriers to entry for new innovators.
