Fri 03 Mar 2007Careful management needed to change to new telecoms networkComment: The Irish telecommunications industry is at a crossroads. The networks and business models that have underpinned the industry for decades are about to undergo radical change, writes  John Doherty.Phone calls, and the revenue they generate, are in decline across the developed world. At the same time, consumers want the benefits that new technologies and converged services can bring. To adapt to this new environment, the industry needs to become more efficient, reduce its costs yet be able to provide new high-bandwidth products and services. Next-generation networks (NGNs) will provide the basis to make this happen.
