Hello everyone! Welcome to the new training series. We will explore MIMO and dive deep into 5G Massive MIMO. I promise that after this training, you will learn important concepts and nuances that will help you understand the details of wireless communication. This knowledge will be valuable in your daily work.

The second session will cover important concepts before diving into the theoretical, practical, and optimization aspects of 5G Massive MIMO.

- What is Massive MIMO?
- Why Massive MIMO?
- 5G Data Stream Physical Layer Processing
- Single User MIMO Introduction
- Mutli User MIMO Introduction
- Reciprocity Based Vs CodeBook Based part 1
- Reciprocity Based Vs CodeBook Based part 2

VoLTE Features: Exit DRX based on SINR

Discover key strategies and techniques to optimize VoLTE quality, ensuring better call performance, reduced drops, and enhanced user experience in mobile networks.

5G NSA Mobility Common Handover Root-Causes

What are the common 5G NSA Mobility Common Handover failures Root-Causes? (1) Missing X2 Definition/Missing Neighbors * Unlike legacy 4G handover scenarios, where missing neighbors may cause quality issues or call drops but not affect the handover KPIs as the handover attempt will not be initiated at the first place

5G SRS Bandwidth Allocation: freqHopping

Did you know that 5G SRS can be configured with either a full-band SRS bandwidth or a narrow-band SRS bandwidth❓ - Purpose of SRS: Let's revisit the basics. SRS serves uplink channel measurement, time-frequency synchronization, and beam management. - Advantages and Disadvantages: So, what are the primary pros
