This links to a useful map which shows the broadband availability for various wireless broadband suppliers on Anglesey. Not all the present suppliers are represented and the figures are from the suppliers them self’s rather than an independent survey.
At the moment ABinternet are included.
As most of the wireless providers use the fibrespeed backbone at Holyhead and Llangefni other providers may have similar coverage areas. It would be good if those supplier also added their data to the map.
