National Broadband Ireland (NBI), the company rolling out the National Broadband Plan (NBP), is set to start surveying works on three Cork offshore islands in the coming weeks.
It said teams will be on the ground on Sherkin, Cape Clear and Bere islands.
"NBI's mission is to ensure that no community is left behind under the National Broadband Plan, no matter how rural or remote their location; and this obviously includes our offshore islands," said Peter Hendrick, Chief Executive Officer of National Broadband Ireland.
"We are very proud that we will provide connectivity to the islands as part of our work, and I am pleased to say that a further three Cork islands are now advancing towards high-speed broadband infrastructure for over 500 homes," he added.
The surveying work informs the network design and determines the locations for essential network equipment, Mr Hendrick explained.
Once the survey is complete, he said they will proceed to the detailed design phase.
"This phase confirms existing infrastructure and identifies any additional requirements, such as power and the necessary footprint for building the network," he said.
"Our planners and surveyors will collaborate with the Local Authority, relevant stakeholders and island residents at every step of the way," he added.
Once the planning and design phases are complete, Mr Hendrick said they will move into construction and provide access to high-speed broadband with minimum speeds of 500 megabits per second.
He said residents can keep up to date on NBIs progress by registering for Eircode-specific updates at www.nbi.ie/eoi or by calling their contact centre on 0818 624 624 where they can also be registered to receive the future updates.
NBI said its infrastructure is already live on ten islands including Hare Island and Long Island off the coast of Cork, Turbot Island and Inishturk South Island off the coast of Galway, Inishlyre Island and Collanmore Island off the coast of Mayo, as well as Inishfree Island, Rutland Island, Eadarinis Island and Eighter Island off the coast of Donegal.
