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.

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, 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.

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.

Currently, one of the hot topics in the telecoms world is Open RAN. This post provides an introduction to O-RAN, where we set up the scene and show basics like characteristics of O-RAN, the basic building blocks as well as entities involved in the development of this concept.

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.
