Open RAN (O-RAN) Webinar Collection

In the past couple of months, we delivered several webinars together with Intelefy University related to Open RAN. In this post, you can find the collection of them, in the particular order, where the first one serves as an overview and high-level discussion, whereas the next ones dig more and more into details of O-RAN, as specified by O-RAN ALLIANCE.

xApp Implementation: O-RAN Traffic Steering Use Case

In this post, we focus on the implementation of a simple xApp tailored for the traffic steering use case. The goal of this xApp is to support the network providers to reassign the traffic from one gNB to the other in order to meet some predefined criteria. We will see some results of the great opportunity offered by Open RAN that the operator can easily install, modify or remove the xApp when needed.

CI/CD in O-RAN design

In this post, we briefly present, how the concept of open RAN meets immediately one of the key approaches in distributed software design, mainly CI/CD. Clearly, these two domains cannot be compared directly, but as we will see, the O-RAN concept modifies significantly the whole software design process.

„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.
