Mobile Communication Technologies and Standards
Mobile Communication Technologies and Standards Mobile networks connect billions of people and devices. Each generation of wireless technology defines how data moves, how fast it travels, and how phones talk to cell towers. Standards ensure devices from different brands work together and can roam across networks without major changes. This shared system keeps phones usable worldwide and helps new services appear smoothly. Two pillars shape these rules: standards bodies and network architecture. The main bodies are 3GPP, which standardizes mobile radio, core networks, and interworking, and ITU, which coordinates global spectrum and service categories. In practice, the network is built from the Radio Access Network (RAN), which connects devices to the system, and the Core Network (CN), which handles signaling, routing, and data services. ...
