ARP was the first commercially operated public mobile phone network in Finland. The technology is zero-generation (0G), since although it had cells, moving between them was not seamless. The network was proposed in 1968 and building began in 1969. It was launched in 1971, and reached 100% geographic coverage in 1978 with 140 base stations. The ARP network was closed at the end of 2000 along with NMT-900.
