📄️ Overview
Welcome to the comprehensive guide on telecom networks! This section covers the evolution of mobile telecommunications from the first generation (1G) to modern 5G networks.
📄️ Mobile Network Evolution
The evolution of mobile telecommunications represents one of the most significant technological advancements of the modern era. Let's explore each generation.
📄️ 2G/3G Architecture
This page provides a detailed look at the architecture of 2G (GSM) and 3G (UMTS) networks, including all major network elements and their functions.
📄️ Circuit vs Packet Switching
Understanding the fundamental difference between circuit switching and packet switching is crucial to understanding how voice and data work in telecom networks.
📄️ VoLTE & IMS Architecture
VoLTE (Voice over LTE) represents a paradigm shift in mobile voice communication, moving from traditional circuit-switched networks to an all-IP packet-switched architecture using the IMS framework.
📄️ Call Flow Diagrams
This page provides detailed call flow diagrams for different scenarios across 2G, 3G, and 4G/LTE networks, showing how calls are established, maintained, and terminated.
📄️ 5G & VoNR
5G represents the fifth generation of mobile networks, offering unprecedented speeds, ultra-low latency, and massive connectivity. VoNR (Voice over New Radio) is the native voice solution for 5G networks.
📄️ Telecom Operations & Concepts
This page covers practical telecom operations concepts including subscriber management, location tracking, inter-operator calls, billing, and special services.
