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.
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.
This study describes impact from James Ohene-Djan's research on personalisation, assistive technologies for the deaf, and web-based video. The research led to two spin-out companies:
(i) Viewtalk was started by Ohene-Djan in 2008 in partnership with Deafax, a charity dedicated to access for people with impaired hearing. Viewtalk developed video messaging specifically tailored to the needs of the UK's nine million deaf and hard-of-hearing people.
(ii) WinkBall was developed in partnership with a privately-owned UK news organisation (Correspondent Corporation). Winkball provided a system that enabled users to post video content for specific audiences and purposes. At its peak it employed 300 reporters to supply dedicated content, and generated a user community of 150,000 active content-generators and three million video watchers.
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.
This case study reports our work on the development, application and dissemination of innovative cloud-based technologies to industrial problem domains. First, decentralised scheduling is implemented within federated Clouds, to facilitate the new drug discovery process for a global pharmaceutical company. Second, multi-objective approaches to the management and optimisation of video processing and analysis workflows in distributed environments is described in the context of an SME organisation that is developing new products, services and markets. Both of these examples have attracted, and continue to attract, commercial funding, and demonstrate the efficacy of knowledge transfer into industry from University of Derby (UoD) research.
Mobile technologies and in particular mobile applications have become key drivers of the economy in many countries especially those that lack established communications infrastructures. Since 2003, the research team led by Professor Al-Begain has created both significant infrastructure and know-how that became the base for the creation of the £6.4million Centre of Excellence in Mobile Applications and Services (CEMAS) that is providing research and development to SMEs in Wales to increase their competitiveness. In the first three years since its inception 28 projects have been completed and 66 companies have received services.
WiFi technologies are integral to our internet-connected lives. Most of the world's wireless data passes over one of the global WiFi standards. For more than 20 years the University's Communication Systems & Networks (CS&N) Group has contributed towards the development of these technologies, and to products that conform to them.
The WiFi standards are vital since they ensure that computers, mobile phones, set-top boxes and tablets all use the same waveforms and protocols to wirelessly connect to the Internet. They ensure inter-operability between different products and manufacturers.
CS&N pioneered the use of multicarrier modulation and multiple antenna (MIMO) technologies. These underpin the current WiFi standards (802.11g/n), ratified in 2003/2009. Research on wireless and video communications led, via spin-out ProVision Communications, to a range of robust wireless-video products for high definition video transmission in the home. These products are now manufactured and sold by Global Invacom.
In partnership with Farncombe, the Group has developed a defacto WiFi test standard. This combines the Group's rigorous WiFi antenna validation & verification measurements with its system level in-home modelling and measurement tools. [text removed for publication]. To date, more than five million WiFi routers have benefited from the University's WiFi test process.
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.
Video surveillance or monitoring is an important ingredient of modern life. Research conducted by the 2017Centre for Information, Intelligence and Security Systems` (CIISS), into improving the reliability of automated detection of visual entities in videos, has made an impact on public services and on practitioners (increased speed and quality, lower labour cost — Beneficiaries: U.K. Police; police investigators) and their health (mitigation of potential physical or psychological harm — Beneficiaries: police investigators), on society (reduction of a factor associated with crime rates and legal costs — Beneficiaries: the public; tax-payers), and on business (creation of a spin-out company - Adaptive Video Analytics Technologies Ltd — Beneficiaries: UK; and influence on management decisions about technology choices — Beneficiaries: Serco Group plc (HMP Dovegate)).
The worldwide population of mobile TV subscribers had almost quadrupled from 75 million in 2008 to 271 million in 2011, and it is expected to reach 792.5 million by 2014 according to RNCOS report (an industry and consultancy firm) on Global Mobile TV Forecast to 2013. The recent roll-out of 4G in the UK strongly features its capacity to deliver real-time TV programmes and videos with high-definition image quality on their mobile devices. Brunel Wireless Networks and Communications Centre developed a global schema, DVB-CBMS (Digital Video Broadcast - Convergence of Broadcast and Mobile Service), subsequently adapted as OMA-BCAST (Open Mobile Alliance - Broadcasting Services Enabler Suite), which enables users to access mainstream TV channels at real time through various networks such as DVB-H in Europe, DVB-SH (satellite) in the USA and DVB-NGH in China.
OMA-BCAST has been successfully used in South Africa, Nigeria and Ghana since 2010: a digital satellite TV service provider, DStv Mobile, delivers mobile TV programmes to its 6.7 million subscribers in Africa. In Europe, 3 Italia offered DVB-H customers free access to six TV channels in 2008; 3 Austria had 90,000 subscribers to its DVB-H mobile TV service between 2008 and 2009. Major mobile phone manufacturers such as Nokia, Samsung and LG have launched special mobile TV editions (e.g. Nokia 5330, Samsung, Philips, Garmin, LG, Motorola, Sagem, ZTE, etc) using DVB-H technology and the convergence system.
