I DON'T BELIEVE Ireland's first city-wide hotspot is Carlow, mainly because it's not really city-wide. Many Irish towns like Carlow have rings of fibre under their pavements so it's good to find a use for that fibre. On national news and through several industry mailing lists, Carlow announced that it's wifi all around. Not yet. Carlow's Wi-Fi network covers only half of all businesses and no more than 10% of homes in Carlow town.
