The study provided coverage statistics for in-home propagation at different frequencies, and in particular obtained a comparison between coverage statistics at 2.4 GHz and 5.8 GHz.

The background requirement was to understand the possible utility of UHF spectrum for Wi-Fi type applications, and to understand the opportunities and limitations afforded by the 5 GHz band in addressing over-demand at 2.4 GHz.  Measurements were made of (i) path loss using CW transmissions at 500 MHz, 800 MHz, 2.4 GHz and 5 GHz and (ii) the throughput obtained using representative 802.11 equipment at 2.4 and 5 GHz.  A clear correlation was demonstrated between the statistics of path loss and throughput at the higher frequencies, and this allowed extrapolation of the results to the 500 MHz and 800 MHz cases.  The measurements were made using techniques broadly representative of available consumer technology.  Measurements were carried out, in the winter of 2010/2011, in a selection of houses broadly representative of the UK housing stock.  The CW measurements were made simultaneously at four frequencies, with continuous logging of signals received at a ‘hub location’ from a transmitter carried around each room of interest.  Measurements of throughput were made using standard 802.11n equipment. The results allowed graphs to be prepared showing the percentage coverage possible within UK homes using the different frequencies.
