GSM is the most successful mobile technology till date.
GSM is the short form for Global System for Mobile communication.The GSM Association estimates that 80% of the global mobile market uses the standard.GSM is used by over 1.5 billion people across more than 212 countries and territories.
The GSM standard has been an advantage to both consumers, who may benefit from the ability to roam and switch carriers without replacing phones, and also to network operators, who can choose equipment from many GSM equipment vendors.GSM also pioneered low-cost implementation of the short message service (SMS), also called text messaging, which has since been supported on other mobile phone standards as well. The standard includes a worldwide emergency telephone number feature (112).
But the question is what actually GSM is and how it works.
In next several tutorials we will learn how GSM changed lives, with a simple and effective technology.
But to really understand it, we must understand what cell phones are and why they are so called and how they have made our lives simpler.
A cell phone is a mobile device, which helps us to connect to the network on the go. The beauty of a cell phone is in hand-offs or hand-overs, i.e your connection can be transferred to other stations, without disconnecting it.
The another feature is the the good use of resources in GSM.
In the upcoming series we will learn about GSM , its architecture, the concept of handovers, the concept of channels and other features that are used in GSM.
