In 2014 we examined to what extent a new class of devices - white space devices (WSDs) - could cause interference resulting in video and audio quality degradation, for both programme-making and special events and for digital terrestrial television.
In 2014 we conducted research into machine-to-machine (M2M) communications, an emerging area with a large and growing range of applications. These include better management of city infrastructures, greater building security, more regular flows of transport traffic, improving energy efficiency, and health monitoring.
In 2013 we carried out research into Long Term Evolution (LTE) technology, which was expected to offer a range of benefits to end users, including the potential for increased data rates and lower latency compared to existing 3G networks.
In 2013 we conducted a survey of IEEE 802.11 WiFi usage in the 2.4 GHz and 5 GHz bands at various urban locations in the UK, to gain a clearer understanding of the state of these licence-exempt spectrum bands.
This 2011 project aimed to identify the best available information on the relative increase in capacity for 4G systems relative to 3G, while identifying the technical and demand factors which create variability in the results.
A 2009 report evaluated the policy of charging spectrum fees based on Administered Incentive Pricing (AIP), i.e. setting fees to reflect the opportunity cost of spectrum denied to other uses and users, rather than just the costs of managing the radio spectrum.
In 2003 the Radiocommunications Agency commissioned a study from Indepen and Aegis, together with Warwick Business School, to review the application of AIP to radio spectrum.
Ofcom received two reports on the international framework of spectrum management. These were commissioned by the Radiocommunications Agency as part of the Government's response to the independent review of radio spectrum management by Professor Martin Cave.
The Ministry of Defence conduct occasional tests on military systems which may result in some loss of service to civilian users of the Global Positioning System (GPS) including in-car navigation devices and networks which rely on GPS signals.
