Impact of QoS research on the global TETRA radio standard

Summary of the impact

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.

Development of International Standards which have fuelled the rapid global development of telecommunications technology

Summary of the impact

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.

Winkball: connecting people through video

Summary of the impact

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.

Wireless LAN - pioneering research underpins standards and improves wireless video performance (for redaction)

Summary of the impact

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.

Enabling high-quality, low power mobile broadband services

Summary of the impact

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.

Delivering Real-Time Mobile TV Services

Summary of the impact

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.
