About Global System for Mobile Communications
GSM is the most popular standard for mobile phones in the world. The ubiquity of the GSM standard makes international roaming very common between mobile phone operators, enabling subscribers to use their mobile phones in different countries.
The main advantage of GSM systems is higher digital voice quality and low cost alternatives to making calls such as text messaging. The GSM system was designed to authenticate the subscriber using shared-secret cryptography. Communications between the subscriber and the base station can be encrypted. |
