About CelticAbout CelticAbout CelticAbout Celtic
Celtic is a European research and
development programme, designed to
strengthen Europes competitiveness
in telecommunications through short
and medium term collaborative R&D
projects. Celtic is currently the only
European R&D programme fully dedi-
cated to end-to-end telecommunicati-
on solutions.
Timeframe: 8 years, from 2004 to2011
Clusterbudget: in the range of 1
billion euro, shared between govern-
ments and private participants
Participants: small, medium
and large companies from tele-communications industry,
univer-
sities, research institutes, and
local authorities from all 35 Eure-
ka countries.

ing telephony wiring, and sincethere is no standard in this
respectnew requirements need to be de-fined. Power consumption is
alsoa significant issue, not only fromthe environmental point of
view butalso from a practical perspective,as battery powered
emergencyoperation is an important require-ment.
The use of the existing telephonywiring forms one of the main
chal-lenges, as this wiring was de-signed for the transport of
voice-band frequencies (300 3400 Hz).4GBB rates require to extend
thisfrequency range up to 300 MHzand very little is known about
theperformance beyond 30 MHz, so
to build up the missing knowledgeCable and Noise Measurements
will be performed and Models willbe created. Performance will
bestudied in reference scenarios,and methods for Qualifying
andMonitoring the Loop will be de-veloped.
The requirements and modelsdefined will allow the Develop-ment
of Transmission Tech-niques for the Physical Layer (PHY) that will
enable the efficientoperation in the proposed ex-
tended frequency range overcom-ing problems like signal
attenua-tion, crosstalk, noise and impair-ments. The main lines of
workinclude Spectrally Efficient Modu-lation Techniques, Multiusers
t r a t eg i e s and P recod ingSchemes and Dynamic
SpectrumManagement and Scheduling.Finally, a scenario for 4GBB
using
PanLab is envisioned: a set-upwhere new 4GBB
infrastructuralelements will be tested and vali-dated and that will
end up becom-ing part of the PanLab infrastruc-ture.
Main resultsMain results from 4GBB projectinclude feasibility
studies, impacttowards standardization and refer-ence designs. But
also, and in linewith PanLab vision, demonstrationprototypes will
be developed.
The 4GBB consortium will dis-seminate and exploit its results
onvarious levels: scientific publica-tions and presentations,
imple-mentation of a public web site(http://www.4gbb.eu),
organisationof tutorials and seminars, creationof an ultimate DSL
reference de-sign, contribution to standards,and submission of
patents.
Impact4GBB project results will make itpossible to provide a
large numberof European citizens with an eas-ier and cheaper higher
bandwidthbroadband access. This will pro-mote the creation of new
services
and products, and new promisingbusiness will emerge, from
whichSMEs will benefit due to theiradaptability and ability to
quicklyexploit the capacity.
The early development of UltimateDSL technologies and the
concep-tion of new standards would giveEuropean industrial
companies aclear advantage in the broadband
area. Also, a timely large-scaledeployment, enabled by a
reliablelow-cost low-maintenance solution,would make Europe the
leadingmarket for the development anddeployment of new services.
Thiscould lead to a new era of commu-nication-driven economical
growth,based on an ecologically sustain-able development where
on-linemeetings are substituting personalappearance and polluting
trans-portation of people.
