Revenues in the Nordic mobile communications market grew by 4.0% during 2004 to 8,200 mln euros, according to Berg Insight. Lower prices can be beneficial for mobile operators since it attracts additional traffic from fixed lines to mobile networks. This fixed-to-mobile substitution trend is already visible, especially in Finland where 39% of the households only use mobile phones for voice calls. Nevertheless the Nordic mobile operators will to an increasing extent have to rely on data services to generate new growth in the future. Nordic wireless M2M communication market is surging and until 2010 at least 1 mln new connections will be added in the utility segment alone after decisions by leading energy companies to install automated meter reading.
