Description

Let's dive into the world of telecom networks, starting from square one. No need for tedious jargon about 2G, 3G, 4G, or 5G - we'll keep it simple and fun!Section 1. Telecom Network Overview•Evolution of telecom technologies from 2G to 5G•Standards & Specifications by 3GPP & ITU•Telecom Network Architecture•What is Telecom Mast•Different Types of Masts/Cells•Different Types of Antennas•What is User Equipment•Radio Access Network•Transport Network•Core NetworkAs technology evolves, so does its incredible architecture. Witness the magic of fewer nodes required to do the same job, and the mind-bending capabilities of emerging tech.Section 2.
