While basic communications protocols for the Internet were developed decades ago, new requirements such as bandwidth-hungry multimedia and the need for the Internet to reach the "final third" of the population create constant demand for improvements. Research at the University of Aberdeen has greatly contributed to meeting this demand by influencing the standardization and implementation of the Internet Protocol (IP) stack in commercial networks. New standards for Internet Transport Protocols and Satellite IP Transmission resulting from the research have been implemented in industrial products in Europe and the US, benefitting industry and millions of end users.
Pioneering research at Bangor on the advanced communications technology termed Optical Orthogonal Frequency Division Multiplexing (OOFDM) has enabled industrial impact with global implications. OOFDM was a candidate technique for the ITU-T G989.1 NG-PON2 and the IEEE 802.3bm standards and is currently under consideration by the IEEE 802.3 400Gb/s Ethernet Study Group. Supported by 8 patent families and first-phase funding of £1.1M, in 2013, the pre-revenue Bangor University spin-off company Smarterlight Limited, was established. Smarterlight has deployed services to several international telecommunications companies to develop advanced solutions for access optical networks and data centres.
As a key participant in the Internet Engineering Task Force (IETF), Dr Perkins has been instrumental in developing key protocol standards that underpin modern telecommunications. The Real-time Transport Protocol (RTP) acts as a transport layer distributing audio-visual data across the network, whilst the Session Description Protocol (SDP) describes the format and destination of streaming media. These standards are essential components of 3G and 4G mobile phone standards and form the infrastructure for many fixed telephone networks. They are implemented in Apple's Mac OS X and iOS, Google's Android, and Microsoft Windows, and feature in billions of devices around the world.
Research by Higham, Estrada and Grindrod into new, computable measures for large, dynamically evolving communication networks has allowed the automatic identification of individuals who act as influencers, or efficient listeners. This research insight has been taken up by Bloom Agency (Leeds), a digital marketing and media agency. Bloom has used these ideas to strengthen their Data Insights Team, leading to investment in new jobs, generation of new business and delivery of better results for their clients. Bloom's commercially available real time social planning software product, Whisper, builds directly on the published research, and is at the heart of the agency's success in doubling staff numbers to 60 in recent months, having grown its annual income by 50% to £2.4Million through the use of these new tools.
Impacts: I) Enhanced public engagement with Scotland's cartographic heritage. II) Enhanced cross-sector collaboration around the use and digital delivery of historical maps.
Significance and reach: A major synthesis of Scotland's map history sold >8,000 copies between publication in 2011 and April 2013 and was named `Scottish Research Book of the Year' by the Saltire Society (2012). Three online map collections experienced 2008 — June 2013 access levels >50% higher than those for pre-2008. The newsletter of the Scottish Maps Forum (launched 2008), reached 553 individual subscribers and 117 institutional subscribers (January 2013).
Underpinned by: Research into the mapping of Scotland from the late sixteenth century, undertaken at the University of Edinburgh (1996 onwards).
Lancaster University's pioneering research on Quality-of-Service (QoS) architecture has led to significant impact on the development of TETRA (Terrestrial Trunked Radio) — the digital radio standard used by emergency and public safety services globally. The route to impact was via UK projects on Mobile and Emergency Multimedia. It involved the transfer of QoS technology and know-how to HW Communications Ltd (HWC), a Lancaster-based SME. HWC became instrumental in developing the outcomes of our collaboration in TETRA's Multimedia Exchange Layer (MEX) standard and its specification for TETRA II (or TETRA Enhanced Data Services, TEDS) — a new version of TETRA that enables multimedia data services. MEX was adopted as a new clause in the TETRA II release in 2010. The impact is that vendors of TETRA equipment manufactured after 2010 can implement MEX in their products, thereby leveraging Lancaster's pioneering QoS research to enable applications to obtain the best possible level of service in a standardised way — which is absolutely crucial for the public-safety and related applications for which TETRA is being used.
Researchers in the Centre for the Mathematics of Human Behaviour at the University of Reading have developed a novel approach for the real-time monitoring of evolving social networks. These networks, in which connections between individuals change over time, are an important opportunity for online advertising. The research has been used in collaboration with Bloom Media Ltd to develop a new tool that gives their clients a better understanding of the impacts of social media campaigns. As a result Bloom are leading the field in this area, allowing them to attract major new clients and leading to significant growth of the business. The company now directly employs highly skilled mathematics graduates specifically to work in this area.
Femtocells provide short-range (e.g. 10m) wireless coverage which enables a conventional cellular communication system to be accessed indoors. Their widespread and growing use has been aided by the work in UoA11 by the University of Bedfordshire (UoB).
In 2008, while the femtocell concept was still in its infancy, researchers at UoB with expertise in wireless networks recognised that coverage prediction and interference reduction techniques would be essential if the benefits of that concept were to be realised.
Collaboration with two industrial partners (an international organisation and a regional SME) resulted in tools that enable operators to simulate typical femtocell deployment scenarios, such as urban, dense apartments, terraced house and small offices, before femtocells can be reliably deployed by users without affecting the rest of the network (a benefit of the technology). These tools have been deployed by those partners to support their businesses. A widely-cited textbook, written for network engineers, researchers and final year students, has brought knowledge of femtocell operation to a wider audience.
Essex research has investigated a range of switching techniques to enable efficient routing in optical networks. This research informed the development of the iVX8000 system, the world's first `carrier class' converged switch and transport solution, launched in May 2011 by the network equipment manufacturer Intune Networks Ltd. The development, launch and field implementation of the iVX8000 system have underpinned a period of sustained growth and success for Intune. The company has enhanced its position within the photonics transmission sector and attracted €15M of venture capital and collaborative research funding since 2011.
Our research on cross-layer optimised video distribution over wireless networks has led to wide- reaching economic and societal impact, via the following pathways:
- Standardisation: our research results were directly adopted in WirelessMAN and LTE, the two global standards for the next generation of wireless broadband networks.
- Collaborative research: the work resulted in a product that has been commercialised by our collaborators Rinicom Ltd, an SME specialising in mobile video, and recognised with a Queen's Award for Enterprise (2013), for achievements to which our research contributed significantly.
- User engagement: the work resulted in the deployment of a WiMAX network in Slavutych/Chernobyl, Ukraine; contributing to community regeneration in a UK Government programme to address social and economic consequences of nuclear power plant closure.
