A company that provides telecoms infrastructure is to build 300 new towers across the country.
Cignal said the two year €25m investment programme will see it cover every county in the biggest rollout of new towers in the last 10 years.
The new towers will improve the availability of high speed wireless broadband as well as improve mobile coverage in blackspots.
Cignal currently has a portfolio of over 450 towers and first bought 300 towers from Coillte in 2015. Since then it has spent €15m on additional acquisitions and organic expansion to add a further 150 sites.
Cignal's chief executive Colin Cunningham said the company's infrastructure provides the platform from which operators can deliver high-speed broadband and mobile services to their consumers.
"Though our strategy of hosting equipment for multiple operators on each tower they can provide a much more cost-efficient service," Mr Cunningham said.
"With offices based in Galway and Dublin we are currently active in every county in Ireland with new sites coming on line every month," he added.
Meanwhile, Aurora Telecom has started work on the final section of Dublin to Cork fibre optic link loop.
This is part of a €35m plan to expand its "dark fibre" - ultra high capacity fibre - infrastructure.
The new section of the network will serve Cork, Waterford, Kilkenny, Carlow and Kildare and is expected to be completed by the third quarter of next year.
Aurora, which is part of Gas Networks Ireland, said the new network will open up new regional job creation opportunities from both Irish and International investments.
The company said that as much of the network has been designed to sit alongside the national gas network, it is subject to regular screening to monitor for interference.
It said this means that the Aurora network is the most secure in Ireland - a key consideration for users, where even a minute of downtime could result in significant losses.
Denis O'Sullivan, Managing Director of Gas Networks Ireland, said Aurora is ensuring that companies seeking resilient high capacity data networks can now choose locations not only in Dublin but throughout the country while retaining the same level of national and international connectivity.
"The completion of this additional Dublin to Cork link will be a major step forward in terms of Ireland’s connectivity. Not only will it create opportunity for businesses in those cities, but it will strengthen the resilience of the entirety of our dark fibre network," Mr O'Sullivan said.
"Aurora already facilitates the connectivity needs of some of the largest tech companies in the world, based in Ireland. This investment will further strengthen Ireland’s position as a technology hub," he added.
