2G to 5G Mobile Technologies

We also have 2G to 5G Mobile Technologies (On-Demand).

2 Days / Technical Level: Level 2

Course Code:  MB1101

This course provides a comprehensive understanding of Mobile Technologies at a technical overview level, and is ideal as a foundation for a wide range of job functions and roles within telecommunications and adjacent industries.

The programme builds a solid understanding of 2G (GSM), 3G (UMTS), 4G (LTE) and 5G, focusing on the most important aspects of cellular communication technologies and how the principles are applied within each generation. This includes techniques that support basic GSM Voice and SMS, through to the complex set of network and connection requirements needed for advanced 4G and 5G services and use cases. Services, Air Interface, Radio Access Networks, Core Networks, Transmission, Interworking (between generations), and end-to-end connectivity aspects are all considered in order to build a complete picture of modern networks.

On completion, participants will be much better placed to significantly contribute across a wide range of projects and business activities within their own organisation.

Who would benefit
