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
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
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.

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
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.
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
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
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
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.
