farsímasamband

Farsímasamband is the Icelandic term for mobile telecommunications, referring to the wireless system that enables portable devices to communicate with each other and with fixed networks. It encompasses the radio access network, core networks, and service platforms, and supports voice calls, messaging, and data services. Mobile devices use SIM cards to authenticate on the network and access roaming.

Mobile networks operate through base stations organized into cells, with backhaul links to a mobile switching center or core network. The core network provides subscriber authentication, routing, billing, and interconnection with other networks, including the public switched telephone network and the internet. Technologies have evolved through several generations: 1G analog systems; 2G digital systems such as GSM and CDMA; 3G networks (UMTS, HSPA); 4G LTE; and 5G New Radio, which offers higher data rates, lower latency, and new use cases like IoT and network slicing.

Common services include voice calls, short messaging service (SMS), multimedia messaging (MMS), mobile data, and various applications. Markets may use prepaid or postpaid plans, and services support roaming between operators and across borders. Regulatory frameworks allocate radio spectrum, oversee infrastructure deployment, and protect consumer privacy and security. The term farsímasamband thus designates the overall infrastructure and services that enable wireless mobile communications in Icelandic contexts, while being used more broadly across Nordic and Baltic regions.
