2G Cellular Telecom is Launched on Radiolinja's Network


On July 1, 1991 second generation 2G cellular telecom networks were commercially launched on the Global System for Mobile Communications (GSM) standard in Finland on Radiolinja's network.

"Three primary benefits of 2G networks over their predecessors were that phone conversations were digitally encrypted, 2G systems were significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS text messages.

"After 2G was launched, the previous mobile telephone systems were retrospectively dubbed 1G. While radio signals on 1G networks are analog, and on 2G networks are digital, both systems use digital signaling to connect the radio towers (which listen to the handsets) to the rest of the telephone system" (Wikipedia article on GSM, accessed 04-11-2009).
