Minister for Communications Eamon Ryan said a contract had been agreed to deliver the scheme to the remaining 10% of the population currently without cover.
While Ireland has over 1.2m subscribers to broadband, approximately a third of the country is without coverage, affecting 10% of the population.
Now it is planned that everyone will have high-speed internet, no matter where they live, by September 2010.
The company awarded the contract, 3 Ireland, says this will create 170 jobs and promised the 21-month deadline will be met.
Mr Ryan accepted the roll-out should have been completed by the end of this year, but says it is now going to happen and the result will be a boost to employment.
Yet work will have to take place at 390 locations - 160 of which are new.
According to some analysts, this means a requirement for planning permission and scope for possible delays if appeals are lodged.
