Private 4G/5G Networks

CONTENTS

If you want to understand what private 4G/5G networks are all about or if you are planning on building one for your organization, this is the course for you. Whether you come from the IT industry and have been working with switches and WiFi access points or if you have a background developing, selling or building 3GPP infrastructure, this course will give you the tools to understand private networks, and what you need to think about building one. The course covers among other things business/use cases, technology, practical examples and useful tips on how to succeed with private 4G/5G business models.

Note: This course is not delivered with the FoldOut methodology.
