Red de telefonía móvil

La red de telefonía móvil permite la comunicación inalámbrica mediante dispositivos móviles, como teléfonos móviles, teléfonos inteligentes o tabletas. Las redes de telefonía móvil proporcionan la infraestructura necesaria y son operadas por proveedores de telefonía móvil. Además de la red de acceso, que establece la conexión inalámbrica con los dispositivos terminales por radio, existe una red básica que conecta los puntos de acceso individuales entre sí. La red básica garantiza que los usuarios de teléfonos móviles puedan intercambiar información con los que utilizan otras redes de acceso o redes externas. El principal factor de distinción entre las redes fijas y móviles está en la red de acceso. La red de telefonía fija también utiliza una red central similar o la misma, pero, a diferencia de la red móvil, utiliza tecnologías cableadas en su red de acceso.

Mobile network and mobile data transmission

To begin with, the mobile network was planned almost exclusively for voice communication, however, mobile data usage has become increasingly important over the years, especially with the advent of smart phones and tablets. This is also a major reason behind the rapid development of mobile communication standards. Whereas standards such as GPRS or EDGE only enable transmission speeds in the kilobits per second range, modern mobile networks, with 3G or 4G technology, such as UMTS and LTE, achieve bandwidths of many megabits per second. The LTE standard allows transfer rates of more than 100 megabits per second and, by using various different frequency ranges, can cover a large area around the radio mast.

Mobile phone network and modern cloud telephone systems

Thanks to mobile phone networks and modern cloud telephone systems, mobile communication devices can be easily integrated intotelephone systems. The mobile device can connect to the cloud telephone system both via a standard connection through the cellular network, as well as via Wifi. An appropriate client app on the mobile device can make it reachable via a landline number. Also, system functions, such as call waiting, conferencing or switching functions, can be enabled between the cloud telephone system and the mobile network. To enable billing for calls made by mobile users via the central telephone system, features such as Call-Through or Call-Back are available. When changing the type network a mobile user is connected to, a technology called handover allows the conversation to continue uninterrupted.
