I am not familar with this part of the country but I do know there are HS's located on Mish and Tullig might be more even use broadband.gov.ie .
Do KBB resell for say
IBB, Clearwire or Digiweb? If so I am geussing they would the best to enquire for a service from all of the above as usually these HS's will be shared be by mulitple wireless ISP's so it just depends on who already have a presence in your area and if there are still enough free space to offer you a service as wireless ISP's can only provide a certain amount of individual connection's per HS before the HS throughput is maxed out, after that usually the HS will be closed for new sales.
To find out who may be building new HS in your area you can do 2 things 1) call them maybe they will know or they could tag you as a potential customer or 2) check the ISP's website and check their news section as it may give you aclue for say annoucements of investents as these investment's are always ployed into expanding network infrastructure and consequently the $ubscriber base of said ISP.
