Mobiiltelefonivõrk

Mobiiltelefonivõrk, also known as a mobile network or cellular network, is a communication infrastructure that allows mobile phones and other mobile devices to communicate with each other and with the wider public switched telephone network. It works by dividing a geographic area into smaller regions called cells, each served by a base station. These base stations are connected to a mobile switching center, which routes calls and data between mobile devices and other networks.

When a mobile phone is turned on, it registers with the nearest base station, allowing the network to track its location. When a call is made or received, the mobile switching center determines which base station the device is connected to and forwards the communication accordingly. As a user moves between cells, their connection is seamlessly handed over from one base station to another, ensuring uninterrupted service.

Mobiiltelefonivõrgud operate on various radio frequencies and utilize different technologies, such as 2G, 3G, 4G (LTE), and the latest 5G. Each generation offers improvements in data speeds, capacity, and latency. The network also supports services beyond voice calls, including text messaging (SMS), multimedia messaging (MMS), and internet access for browsing, streaming, and various applications. The development and expansion of mobile networks have revolutionized communication and connectivity worldwide.
