Summary of the impact
A new broadcast system involving satellite plus cellular to allow TV and
multimedia to be viewed on a handheld or in a car was first proposed by
researchers at Surrey. The feasibility was demonstrated within an EU
project run by Surrey and then taken to prototype stage via two other EU
projects run by industry. A new standard was produced in DVB / ETSI and
the EU let licenses for operation. A new company was formed
(Solaris-Mobile) by two of Europe's major satellite operators (Eutelsat
and SES) who launched a satellite and now operate the system. Investments
of circa €200m were made by industry to create this new business.
Underpinning research
The basic idea underpinning the system, as proposed by Surrey, is to
integrate the satellite broadcast capability with mobile delivery in the
urban areas that are shadowed from the satellite.
The opportunity was exposed by Surrey researchers noticing that the
mobile allocated satellite bands were adjacent to 3G terrestrial bands and
thus a single and simplified mobile handset could be produced to cover
both, allowing the satellite signal to be picked up and retransmitted by
fixed receivers in the urban areas. In addition it was proposed to have a
single integrated resource management between the two systems providing
maximum efficiency.
In [1] Surrey demonstrated that only minor changes were needed for
operation over the satellite path and an integrated system to be feasible.
The integrated resource management was demonstrated by Surrey in the EU
project SATIN [2], this being a key element of the system.
Two further EU projects followed, MoDiS (2002) demonstrating the
networking principles and MAESTRO (2006) which took the system to a
prototype working terminal and operation via a 3G network with a simulated
satellite. The latter were led by ThalesAleniaspace but Surrey made major
contributions to the research: (1) by producing and demonstrating the
resource management scheme [3] and (2) producing models for the
propagation between satellite and terrestrial components from measurements
made in the trials.
The outcome of MAESTRO was to replace WCDMA in 3G with ofdm (the basis of
LTE) as the air interface — Surrey proved this important update [4], and
contributed to technical reports for ETSI/DVB who produced a new air
interface standard DVB-SH for the industry to develop equipment.
A Surrey patent was granted on a novel receiver system for this air
interface. Subsequent to the commercial interest and take up (see impact
template) further research was completed by Surrey on the IP delivery of
the services and novel packet schedulers [5,6] were invented that form the
heart of the service delivery platform.
The Surrey team was led by Professor Barry Evans throughout. Other key

Details of the impact
Impact has been created from the original idea and research on the
feasibility of the system. Knowledge transfer to industry involved Surrey
working closely with industry in R&D projects. These were first funded
by the EU and then funded by private venture funds by industry itself as
system definition and products emerged. In this way Surrey was involved in
further research which accelerated the movement to a real system.
Knowledge transfer from the University occurred in the following
areas;
- Convincing industry of the viability of the system,
including-satellite operators, satellite manufacturers, terminal
manufacturers and service providers.
- Demonstrating a working system with prototype equipment.
- Convincing EU and ESA to invest €50m in R&D.
- Working with industry to convince DVB/ETSI to develop a new standard
for the system.
- Assisting industry to lobby the EU to create a new and harmonised
license regime for the system.
- Formation of a new company SolarisMobile with circa €100m
capitalisation to run the system.
- Launch of a new satellite and operation of services in Europe.
Thus, from the first research idea created at Surrey in 1999, a system
was actually built and launched within 11 years which included the
R&D, standards for the industry and agreements on spectrum within
Europe. Internationally, Korea launched a similar system in 2008 in
partnership with Japan. In the US there have been trials of a similar
system and two satellites launched but no commercial service is yet
operating.
Impact can be demonstrated in the followings ways:
Economic impact has been created by the ensuing formation of a new
business and a new company. Circa 100 jobs and R&D plus satellite
rollout of €200m have been created in the sector by just the upstream
activity. The potential for downstream wealth creation in terminal sales
and services is estimated at around €1B.
Policy impact was created by a completely new intervention by the
EU to harmonise the spectrum across Europe. This was the first time that
the EU had intervened to operate a `beauty parade' and to offer pan
European licenses.
Societal Impact has been created as the system has enabled
multimedia broadcast to reach regions of Europe that wouldn't have been
economic with purely terrestrial infrastructure. This has and will
continue to contribute to more digital inclusion within Europe and help to
mitigate the digital divide that would otherwise exist for the rural and
remote areas. Current plans are to extend services to personal protection
and disaster warning systems thus adding to the societal impacts.
In recognition the achievement the following statements have been made:
CEO of Solaris says;
`Surrey's role in the formation of this new business area was
crucial and was an exemplar of cooperation between academia and
industry'
The Chair of ETSI SCN says;
`The SDMB area was unique in rapidly creating new standards and
regulations for operation of the system in Europe. Surrey besides
being the originator played a key role in the process.'
EU satellite projects coordinator says;
`This is an excellent example of how funding via a series of EU
projects can create a new business area. Surrey have played a pivotal
role in all of the R&D innovations.'
