Traditional wireless mobile communication

A Cellular device today has become unthinkingly an extension of our anthropological arms that has endowed us with an added means of communication, which we term as wireless communication or mobile telecommunication.

A few millimeters sized SIM card plugged into a mobile device forms a worldwide used network technology called the Global System for Mobile Communication (GSM). What we tend to view as an ornamental handset and a few sprung out antennas with scattered cell towers is part of a complex architecture that fits into our daily requirement. This GSM system can be dissected into three main subsystems: Radio subsystem, Network subsystem, and Operation subsystem.

Lets discuss this hierarchical system breakdown to get a brief overview of how telecom providers are engaged in providing the freedom of speech to mobile users all over.

1. Radio Subsystem –
As we all know mobile communication occurs in the form of radio waves that travel through the medium-air.The radio subsystem includes two main components. These include a mobile station (MS) and the Base Station System (BSS).
