What is the GSM wireless network?

The

Global Communication Network (GSM) is a number of virtually interconnected towers and satellite relays that send and receive digital signals that allow people to communicate wirelessly around the world. The signal begins with a mobile phone that brings a call and travels to the nearest GSM tower. This tower communicates the satellite signal, which in turn transmits the signal to the tower closest to the conversation, where it is then accepted by the recipient of the call. Today, the GSM wireless network is the most popular wireless communication system. This meant that many people could use the same frequency, but the frequency would differ according to the location. During the 90s.

Digital communication networks were the second generation for the second generation (2G) of the mobile phone technology that had less call interference and increased call security, for a digitized signal. Telefo batteryNu took longer and from the network extension it was possible to offer multiple call features. The biggest advantage, however, was that digital capacity efficiency reduced the cost of running a new carrier, allowing smaller players to join industry and offer real competition that leads to lower prices of services.

When digital communication has evolved and networks developed, standards were set standards that would allow the towers to transmit a signal from any carrier, regardless of which tower carriers belonged. So the GSM wireless network, which currently operates in 900 Megahertz and 1.8 gigahertz belts in Europe and 850 Megahertz and 1.9 gigahertz bands in the United States, Canada, Australia and South America. Accepting uniform Standards allows mobile phones to work abroad as well as at home.

GSM wireless network system currently boasts coverage in 218 countries and servesMore than 3.8 billion customers. There are very few areas where GSM coverage is unavailable - usually very distant rural areas - and specialized satellite roaming functions are available to cover all gaps in coverage. 89% of GSM market share means that new mobile technologies are usually created in accordance with GSM standards and GSM wireless network technology has evolved along with it.

GSM now carries third generation technology (3G) mobile phone and also the fourth generation (4G), which allows users to transmit more voice and data streams simultaneously. Every new GSM incarnation is compatible with each version that has come earlier, eliminating the need for customers to upgrade their phone every time a new technology is released.
