Open and virtualized RAN, Open vRAN refers to a disaggregated approach of deploying virtualized mobile networks by using open and interoperable protocols and interfaces, implemented over a common propose hardware in a multi-vendor software environment, allowing increased flexibility over traditional RAN architectures., aiming to provide OPEX and CAPEX savings while fostering innovation. Traditional RAN Protocol […]
What is the difference between Traditional RAN and Open RAN?
Industry Alliances and Organizations 3GPP,O-RAN and TIP
Industry Alliances and Organizations Multiple industry groups are working on 5G deployments and standards. These groups include: O-RAN Alliance: A group of telecom companies focused on fostering wireless networks that are open software-defined and virtualized, enabling architects to mix and match products from different In 2018, the xRAN and C-RAN organizations merged to form O-RAN. […]
Functional Split Options for 5G Networks
Functional Split Options for 5G Networks As network architects work to meet the 5G challenges of increased traffic and data flows, a fundamental question is how much intelligence to put near the antenna versus at the DUs or CUs. Mobile Network Operators (MNOs) as well as industry-standards groups, such as the 3GPP, IEEE, Telecom Infra […]
The Importance of RAN Intelligent Controller (RIC) in O-RAN Architecture
The main motive for the RAN Intelligent Controller (RIC) is to bring software-defined controllability to RAN to increase system performance as on the path towards 5G, with network densification, and availability of different types of spectrum bands, it is increasingly a more difficult task to optimally allocate radio resources, implement handovers, manage interference, balance load […]
What is RAN Disaggregation?
In the cellular network, RAN provides wide-area wireless connectivity to mobile devices. Towards this end, it conducts two fundamental tasks: It converts IP packets to Physical Layer packets suitable for transmission over the time-varying mobile channel using packet and signal processing techniques. It conducts Radio Resource Management (RRM) control to determine how best to use […]
The “Cherry” Release of O-RAN Open Software
The “Cherry” Release of O-RAN Open Software • Cherry features significant advancements in the end-to-end integration of O-RAN Architecture components. • The software now contains new functions aligned with the latest O-RAN specifications, such as the E2, A1 or O1 interfaces. In December 2020, the O-RAN Software Community (OSC), working with the Linux Foundation, published […]
