NMT (Nordic Mobile Telephone) A 1G analog cellular radio technology developed and placed into service in the early 1980s in Scandinavian countries, including Denmark, Finland, Norway, and Sweden. NMT 450 operates in the 450 MHz band, which yields excellent signal propagation and, therefore, is especially appropriate for sparsely populated areas supported by few cell sites. NMT 900 operates in the 900 MHz range. NMT largely has been replaced by GSM. See also 1G, analog, cellular radio, propagation, GSM, NMT 450, and NMT 900. |
