These 3G coverage maps by mobile operator were prepared in January 2009 by Ofcom. The shaded areas on the maps indicate areas where customers have the possibility of making and receiving a call outside over a 3G network (but with no guarantee of being able to do so). They do not indicate areas where customers are able to access higher data rate services.
All operators produce their own coverage indicators on their websites which are likely to provide more reliable guidance to network availability in any given area. The accuracy and detail of the maps are not to the same level as the mobile operators publish. These maps show UK-wide general coverage and are not suitable for zooming in to see specific locations i.e. a particular house or street. Also they are not suitable for assessing the quality or depth of coverage within the indicated areas (e.g. different operators may be able to offer better or worse data rate services or support a smaller or greater number of users).
It should be noted that the data used to generate the maps was not collected for the purpose of examining detailed mobile coverage therefore the availability or quality of mobile services cannot be assumed from these maps.
The coverage maps are based on theoretical predictions and were used as an intermediate step for Ofcom establishing the operators compliance with their 3G licence rollout obligations. For the full details see the consultation and statement on assessing compliance with the 3G rollout obligations on the Ofcom website: http://www.ofcom.org.uk/consult/condocs/3g_rollout/. The maps only provide a snapshot of the extent of network coverage achieved by the operators at 31/12/2008 against the relevant coverage threshold.
The maps are provided without any representation or endorsement made and without warranty of any kind, whether express or implied, including but not limited to the implied warranties of satisfactory quality, fitness for a particular purpose, non-infringement, compatibility, security and accuracy.
