Ofcom has been working on techniques to use ‘white space’ spectrum since 2012 (Display Monitor Vol 18 No 48). The regulator will use the results of technology trials (currently ongoing at London Zoo: http://tinyurl.com/mv44esj) to determine whether there is any disruption to other frequency bands. Ofcom hopes to roll out white space technology across the UK next year.

White space is the common name for gaps in the radio spectrum that appear between TV broadcasting frequency bands. The ‘gaps’ are of a lower frequency than the UK’s current Wi-Fi spectrum (2.4GHz) and 3G data (2.1GHz), enabling a wider range. They can also travel through walls more easily. (TA)
