In April 2008, Imagine Communications Group acquired Irish Broadband from National Toll Roads and Kilsaran Concrete.
[citation needed] The company provides wireless broadband services for residential and business customers, including up to 4Mb symmetric DSL links (4:1 contention ratio).
Services are provided by means of transmitters located on high points (e.g. tall buildings or hills).
As of 2005[update] these are located in the main cities in the Republic of Ireland, providing local services in those urban areas.
Company representatives have stated that problems resulting in low service levels arose from rapid growth in customer numbers, with an increase of 1000% in one year[when?].
