Senior ´óÏó´«Ã½ R&D Engineer not only presented a paper at but also won the for his contribution 'Compatibility Challenges for Broadcast Networks and White Space Devices'. Mark kindly agreed to share the paper on the Internet blog (download links at the end of this post) and also to write an introduction aimed at the layperson (and this blog's editor!). Mark writes:
"My paper discusses proposals to allow license exempt use of TV spectrum by WiFi-like devices known as White Space Devices (WSDs). This would enable improved wireless networking but there is a significant risk of interference to our Freeview services. The paper looks at the technical parameters for WSDs to manage the interference problem. Researchers in the United States are leading the work in this area and have been applying considerable influence to Ofcom. The US companies are less concerned about DTT interference, however, as only 10% of the population receive TV through a conventional antenna; 90% have cable or satellite. In the UK, Freeview is used by over 70% of the population, so interference would be a major worry."

Keep the TV spectrum for HIGH QUALITY TV. We will need as much spectrum as possible for a high quality Freeview HD with as many high quality (high bitrate) HD channels at full HD. Do not sell of our spectrum for WiFi or other similar uses.
