What is the GSM network?

The

Global Mobile Communication Network (GSM) is a standard system used mostly by a network of mobile phones around the world. Whether the system uses a cellular network based on broadcasting stations or satellite technologies connected to signals from orbit, both types can be part of the GSM network. According to statistics of accumulated organizations known as the GSM Association, about 80 percent of all mobile phones around the world are part of this network. Phones on this type of network use a subscriber identity card (SIM), while those that have the main competitive technology, code divisions (CDMA), no.

GSM function

One of the main purposes of the GSM network is easier to access the cellular and satellite platforms across international lines. Using digital technology, it uses speech and data channels in its system. At least these channels work on the second generation network (2G), but many use the third Gensystem Eration (3G) or higher to make theseThey offered the services to clients.

This allows you to exchange information at high -speed data speeds through satellites and mobile cell towers across the company's networks and lines. For example, a person in Tokyo can text message with someone in Toronto through a Japanese system, via networks in countries between the countries until they finally arrive on the recipient's mobile device in Canada. In particular, the network was necessary when introducing worldwide access to emergency telephone services using One-One-TWO (112), which redirects global telephone traffic to emergency respondents near the user. He is also responsible for creating text messages over 90 years.

History and Origin

The GSM network was created in 1982 with a meeting between high -level communication experts at the European Conference of Post and Telecommuser Nimics. Its original purpose was to solveCell infrastructure in Europe, but has quickly spread to other nations. Many GSM standards and operating procedures are published in annual magazines. These experts help to streamline communication protocols from one system to another.

Frequency used The

GSM network works on different frequencies depending on the system used, whether 2G or 3G. Each frequency is then divided into different channels that allow you to send short explosions of digital information via the GSM connection. North America networks operate at different frequencies than in Europe or Asia. Much of this has to do with the mere volume of mobile phones in certain parts of the world and the fact that Canada and the United States have already assigned certain frequencies for other uses.

SIM card on GSM

GSM phones usually use a SIM card that stores data on the phone and its users, making it easy to convert this information to another device. Many mosketGSM's Waters use "Sim Locking" to keep a person in a particular network during the contract period. When the contract is complete, the card can be used in a new phone or other network. Competitive CDMA technology does not use these cards and requires that the data stored on the phone be transmitted manually or via the connection.
