5g Introduction

Massive MIMO and beamforming, multi-user MIMO, and ultra lean design improve 5G capacity and efficiency by allowing networks to serve more users simultaneously. Dynamic TDD and reduced TTI lengths in 5G help lower latency by enabling more flexible resource allocation and shorter processing times between transmissions. These 5G radio technologies are essential for enabling new applications that require high bandwidth and low latency wireless connectivity.
