„The O-RAN Whitepaper”

Open RAN, as a new approach to building mobile networks, offers faster innovation and the possibility of lowering costs. This whitepaper provides an overview of Open RAN in general, and O-RAN specifically. The O-RAN concept, relevant standardization, and ecosystem players are introduced. The architecture as defined by the O-RAN Alliance is described. Near-Real-Time RAN Intelligent Controller (RIC) along with the idea of xApps is discussed. The use cases for O-RAN are overviewed with a particular focus on Traffic Steering.

what is open RAN

What is Open RAN?

Like almost everything in Telecom's, Open RAN is complicated. It's not a single idea. It's not a single product or service. It's not an optimization technique or path towards improved efficiency. It’s hardly even an agreed term. Open RAN is essentially 2 foundational ideas: 1) The disaggregation of network functionality from the underlying hardware. 2) The specification of discrete functional blocks having well-defined interfaces. In other words, modularity.

3GPP Rel-18: The Preliminary Discussions

According to 3GPP the prioritization process on Rel-18 features should be completed by the end of 2021 - with the Rel-18 Package Approval scheduled for December 2021. As of now, the decisions are still focused on the Rel-17 schedule. Meanwhile, some Rel-18 Stage 1 studies are underway.

O-RAN Use Cases

O-RAN Use Cases: Traffic Steering

The O-RAN Alliance specifies certain use cases with requirements that provide a landscape for the development of xApps. This post provides an overview of the use cases and discusses in more details one of them, namely Traffic Steering. This use case is being developed in various open source implementations as one of the initial practical applications within O-RAN framework.

O-RAN RIC

O-RAN near-Real-Time RIC

This post describes the near-Real-Time RAN Intelligent Controller. RIC is the heart of the O-RAN system, where the intelligence sits allowing to control and optimize the radio network. The RRM algorithms can be deployed at near-RT RIC by means of xApps defined on a per use case basis.

RIMEDO Labs joins the ONF to collaborate on the O-RAN compliant RIC

RIMEDO Labs, has joined the ONF, a non-profit operator-led consortium driving the transformation of access and edge network infrastructure. Within ONF, RIMEDO joins the SD-RAN project focusing on building open-source components for the Open RAN space in compliance with the O-RAN Alliance’s architecture and specifications. The key element of the SD-RAN project is the development of an open-source near-Real-Time RIC along with a set of exemplar xApps for controlling the RAN.

O-RAN Architecture

O-RAN Architecture, Nodes, and Interfaces

This post discusses the nodes and interfaces defined by O-RAN Alliance. The provided implementation options visualize one of the benefits of O-RAN, namely the implementation flexibility with the open O-RAN architecture. Those options from one side provide the flexibility in implementation and various vendor configurations, but the price to pay for this variety is that you need a way to identify the internal nodes.

5G mmWave Webinar Summary

During the talk it was explained what is the difference between currently used “sub-6 GHz waves” and introduced for mobile service mmWaves. Among key differences in these bands enhanced path loss was mentioned and antenna arrays as potential enabler to overcome high path loss in mmWave.
