TRANSCRIPT
Extending Lifetime of HFC Networks
– An EU FP 7 Research Project
Slide 2Introduction to the project
The Cable Business Challenge
• MSOs facing increasing competition– Incumbent telecom operators roll out advanced DSL platforms (e.g.
ADSL/ADSL2+, VDSL) for delivery of triple play services– Operators of new technology platforms (e.g. FTTH, WiMAX) emerge – Over the top providers take up expensive cable bandwidth
• Hybrid Fiber Coax Cable networks– Superior technical broadband infrastructure – Valuable assets of operators– Will need to evolve technically to stay competitive in an increasingly
challenging business environment
• What can be done on the technical side to help MSOs facing these challenges?– Short-to-mid term enhancements– Mid-to-long term evolution
Slide 3Introduction to the project
The Objectives
• Optimise & renew current HFC technologies– Optimise the HFC frequency/power plan– Advance HFC amplifiers and nodes– Support DVB-C2 standards development– Consider DOCSIS technical requirements
• Develop techniques for the Next Generation HFC network and platform– Improve the cost structure of CAPEX and OPEX– Leverage existing HFC assets as long as possible– Investigate architectures that allow gradual introduction of fiber
deeper in the network
Slide 4Introduction to the project
‘s 4 Step Approach
1. Inventory of HFC Structures: Reference Architectures & Requirements for Network Evolution
– Input from MSOs required
2. HFC Network Improvements– DVB-C2, all digital, frequency/power plan
3. Next Generation HFC Systems – New technology and architecture approaches
4. Dissemination of Results and Standardisation– DVB, CENELEC, MSO – if appropriate

Slide 8Introduction to the project
EC 7th Framework Program
• EC stimulates R&D by large scale “Framework Programs”
• FP7 2007 – 2012 or longer• In 2007 call ICT “Networks of the Future”
€ 180,000,000.00– xDSL projects– Optical projects– Wireless broadband projects– Cable projects – ReDeSign only
• No other ICT Call in FP 7– Thus no other opportunity for such work
Slide 9Introduction to the project
Work Packages
• WP 1: Project Management• WP 2: Inventory of HFC Structures and
Definition of Reference Architectures• WP 3: Requirement for Network Evolution• WP 4: HFC Network Improvements• WP 5: Physical Layer Simulations• WP 6: Next Generation HFC Systems• WP 7: Validation and Demonstration• WP 8: Dissemination and Standardisation
Slide 10Introduction to the project
WP2 Inventory of HFC Structures and Definition of Reference Architectures
• Objectives:– Creation of a thorough database of networks deployed in Europe– Definition of a limited number of reference architectures
• Approach:– A questionnaire is prepared and sent to the community of European
MSOs– Based on the response to the questionnaire, an appropriate number of
reference architectures are defined. The architectures are specified by a set of appropriate network parameters and their variation
• Result:– A good knowledge base of the European cable networks– A set of reference architectures and parameters that will be used for the
optimisation studies of work packages 4, 5, and 6.
Slide 11Introduction to the project
WP3 Requirement for Network Evolution
• Objective: – Determination of the near-term (2-5 year) and long-term (5+
year) network and service requirements
• Approach:– European MSOs will be approached to provide input information
concerning the foreseen service types and the foreseen demand. An overall service forecast and a specification of the commercial network requirements will be prepared,
– The technical network requirements are extractedfrom the above service forecast and commercial requirements
• Result:– A specification of the near-term and long-term commercial and
technical network requirements
Slide 12Introduction to the project
WP4 HFC Network Improvements
• Objective: – Improvement of the HFC network itself (intrinsic performance)
• Approach:– Development of improved understanding and models of the noise in HFC
networks carrying mixed analogue / digital signals or digital signals only– Improvement of the DS and US cable channel models for reference architectures– Improvement of channel planning methodology & improved specification of HFC
components– Development of a new GaN-based RF amplifier with improved performance
(linearity, output power, thermal stability,….)– Development of a new cable frequency plan (amongst others frequency split,
maximum DS band edge) and frequency and power deployment rules
• Result:– A substantial increase of the intrinsic US and DS HFC transmission capacity– Improved tools and components to build such an HFC network with minimum
costs (replacement of amplifiers and nodes)
Slide 13Introduction to the project
WP5 Physical Layer Simulations
• Objective: – Support of the development of DVB-C2 and longer-term advanced physical layer
systems – Support of cable network optimisation investigations– Provision of DVB reference software platform for the DVB-C2 development
process
• Approach:– Development of a software tool for channel coding and modulation for DVB-C2
and next generation cable network – Support of DVB-C2 development by providing a reference software tool– Implementation in software of various cable channel models for flexible
performance investigation of the systems under varying channel conditions
• Result:– Reference software tool for DVB-C2 performance simulation under varying cable
network quality conditions– Reference software tool for next generation physical layer simulations under
varying cable network quality conditions
Slide 14Introduction to the project
WP6 Next Generation HFC Systems
• Objective: – Design access network that addresses the long-term operator needs and that
allows seamless migration from today’s HFC architecture and services
• Approach:– Develop Hybrid HFC – FTTH architecture that allows gradual migration– Investigate advanced coax & fiber transmission technologies, allowing delivery of
>100Mbps symmetrical– Out-side plant design that leverages existing HFC assets
• Result:– Future-proof access network with maximised Mbps/€– Strategy to migrate in a cost-efficient way from today’s HFC to the FTTH end-
game
