„The O-RAN Whitepaper 2023 – Security in O-RAN”

2023-11-03
Recently, security has been pointed out as one of the critical aspects moving forward within the O-RAN domain. Expanded threat surface, as well as specific security challenges and opportunities, have been identified. This whitepaper provides an overview of security topics in O-RAN, specifically in 5G/6G mobile radio networks. We also consider artificial intelligence embedded in the network edge as a great tool to support security. We present some xApps applied to detect and mitigate example attacks. Conclusions and a discussion on the directions of future developments follow this.

Energy Saving-rApp control over Traffic Steering-xApp

2023-08-03
Energy consumption is a critical aspect of any service in these modern times. In telecommunications, a flexible approach to network planning, control, and management is extremely beneficial in this aspect. The concept of O-RAN enables the creation of algorithms that allow energy saving in a manner independent of the equipment or RAN software solution used. In this blog post, we present an innovative approach to energy saving using the RIC, which is based on the direct cooperation of Traffic Steering xApp and Energy Saving rApp.

O-RAN Deployment Scenarios

2023-07-02
Deployment scenarios that the O-RAN ALLIANCE specifies, define how to compose the elements of O-RAN architecture in the actual deployment in the network within the cloud and physical locations. One of the key aspects is that the general split from the deployment perspective is the open Fronthaul, with the the separation between O-Cloud deployed entities, and the PNF, for O-RU component. In this blog post, we are providing an overview of different scenarios and deployment options as presented in the O-RAN resources.

Rimedo Labs Integrated the TS xApp with VMware Distributed RIC and Won the rAppathon

2023-06-01
Rimedo Labs integrated a Traffic Steering xApp into the VMware dRIC. Rimedo’s Policy-Controlled Traffic Steering xApp running on the VMware Distributed RIC incorporates both service and mobility load balancing to avoid congestion, improve user experience and make the network more energy efficient. Rimedo’s xApp was the winner of the inaugural rAppathon RIC application developer competition hosted by VMware and Intel at MWC 2023.

O-RAN Security and Security Offered by O-RAN

2023-05-06
This year, the most crucial topics for further development in O-RAN are security and energy efficiency. In this blog post, we investigate how different players of the O-RAN ecosystem look at the security topic. Those include O-RAN ALLIANCE, the telecommunication business (including operators and providers), governmental bodies, IEEE, and academic researchers.

„The O-RAN Whitepaper 2023 – Energy Efficiency in O-RAN”

2023-04-03
Recently, within the RAN domain, energy efficiency has been pointed out as one of the key requirements moving forward. It has been defined as end-to-end involving all domains within the O-RAN system. The overall objective for O-RAN is to gradually become more energy efficient than the regular RAN. This should not be at a cost of the key O-RAN concepts including cloudification and disaggregation. This whitepaper provides an overview of the energy efficiency topic in 5G mobile networks and how it fits into the O-RAN area. This is followed up by example algorithms utilizing ML schemes and their realization in the form of rApps based on O-RAN use cases.
