WiFi local authority: This file provides information about WiFi networks that are purposely made available to members of the public, by local authority. These can be free, chargeable by time used or available through subscription. The data is based on data provided by BT, Arqiva, Sky, Virgin Media, O2, EE and KCOM for the period of June to July 2014 (this means that there may be other hotspots provided by different operators that are not captured, so the number should be seen as a reliable minimum.) The file should be viewed in conjunction with the Infrastructure Report published by Ofcom in December 2014, which details how each of the metrics is defined.
