Advanced digital communications – Software Defined Radios and O-RAN

If you want to prepare yourself to build practical, and fully open telecom equipment, software programs, and end-to-end 4G/5G systems alternative and competitive to those produced by conventional Telecom companies, such as NOKIA, HUAWEI, SAMSUNG, ERICSSON, ZTE, etc., or want to learn how to build private 4G/5G networks, then this course is just for you. In this course, you will learn in detail most technical aspects of building end-to-end 4G and 5G systems including eNodeB/gNodeB, UE, and EPC/5GC.

After you complete watching all the lecture videos of the course, you will be able to get a professional certificate of completion.


Private networks, no matter who you ask (see: herehere, or here) have transitioned from lab toys to a multi-billion dollar industry. Open source too has left the lab and solutions from the likes of RedHatOpenStackO-RAN Alliance, and the Telecom Infra Project are a growing presence in operators networks globally. As the footprint of open source grows, and network operators see the benefits of deploying open-source, the industry is responding by developing open source solutions moving up the stack. Now with the introduction of the Magma project, open-source is moving into complex network functions like the core of the 4G and 5G mobile network.

Dumping gas on the open and private network fire, the FCC has made available commercially deployable CBRS spectrum that we see taking off in the recent auction and as Spectrum Access Systems (SASs) go live. With its 3 tier access, CBRS means anyone can get a meaningful chunk of airwaves with 25 times (or more) the power of most Wi-Fi networks to deliver high-quality wireless services.

In light of these changes, in this version of the build your own network how-to, I will move our target from a lab network to a commercial-grade LTE network deployment. Let’s get started.

The Ingredients

There are 6 key components to an open and private LTE network:
