Mobilnett

Mobilnett is the term used in Norwegian and several Nordic languages to denote the mobile telecommunications network. It refers to the system that provides wireless voice, text, and data services to subscribers over licensed radio spectrum, and it encompasses both the radio access network and the core network. The term is used broadly to describe the infrastructure operated by mobile network operators and regulated by national authorities.

The radio access network (RAN) forms the wireless linkage between user devices and the core network. It consists of base stations, antennas, and related transmission equipment that deliver wireless coverage and capacity. The backhaul connects base stations to the core network, typically using fiber, microwave links, or other high-capacity media. The core network handles signaling, mobility management, authentication, roaming, and data routing, enabling services to be maintained as users move between cells and networks or travel internationally.

Mobilnett has evolved through multiple generations of technology. 2G introduced digital voice and basic data services; 3G expanded mobile internet access; 4G LTE provided higher data speeds and more efficient packet switching; and 5G offers substantially lower latency, greater capacity, and features such as network slicing to support diverse applications and services.

Operational aspects include licensing of radio spectrum through government regulators and coordination for roaming and interoperability. Standards are maintained by bodies such as 3GPP to ensure compatibility across equipment and operators. Related topics include mobile network operators, base stations, and core network architectures.
