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.

This article discusses the private (or non-public) mobile networks from the technical perspective. It touches upon 3GPP features related to Private 5G Networks and various options for the deployment of those along with an analysis of advantages and disadvantages for each.

How to predict the power received in the given area when mmWaves are in use? This post describes three classes of propagation models can be addressed starting from very basic to precise ray-tracing models for mmWaves.

We recently took part in the 5G Core Summit by Informa and Knect365, a virtual conference, which I'd like to shed some light on. The conference's main areas included: 5G use cases and ecosystem development, network cloudification, edge clouds, and network slicing, trials and lessons learned from initial deployments, specialized use cases, private networks and practical aspects of the first implementations, evolution strategies, and alike.
