NMT

Nordic Mobile Telephone

A first-generation (1G) analog mobile telephone system used in the Nordic countries (Denmark, Finland, Norway, Sweden) and some other countries during the 1980s and early 1990s.

NMT was developed by the Nordic telecommunications administrations to establish a standardized mobile telephone system across the region. It operated in the 450 MHz frequency band and used analog transmission for voice communication.

NMT employed Frequency Division Multiple Access (FDMA) to allocate channels for communication. It divided the available frequency spectrum into multiple channels and assigned each channel to a specific user. This allowed multiple users to communicate simultaneously within a given cell area.

NMT had a larger cell size compared to modern cellular systems, which meant that it required fewer base stations to provide coverage. However, it also had limitations such as limited capacity, lower voice quality compared to digital systems, and vulnerability to eavesdropping.

As digital cellular technologies like Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) emerged, NMT networks were gradually phased out and replaced by these more advanced and efficient systems.

Today, NMT is considered a legacy technology, but it played a significant role in the early development of mobile telecommunications and laid the foundation for the subsequent generations of mobile networks.
