GANDALF Overview
Access network scenario: • Co-existence and interoperability between wireline and wireless
access technologies
• Upgradeability, multi-band/multi-service capabilities and cost effectiveness
Proposes a novel optical feeder concept that allows co-existence of wireless and wireline access networks using a shared fibre-based infrastructure.
- Both BB/IF and RF signal reception- Dispersion tolerant- Same modulationn scheme regardless of the access medium - LO remoting for downstream capabilities

Project key issues• Highly flexible approach (simultaneous operation at BB/IF and mm-wave bands)
• Reduced hardware requirements reduced cost and complexity at both BS & CS
• Operational up to 60 GHz using state-of the art components
• No dispersion induced RF fading
• The proposed architecture is fully compliant with DWDM schemes
• Simultaneous service provision in two frequency bands: BB/IF and mm-wave (e.g. CEPT DVB-S @10 GHz and LMDS @40 GHz compliance)
• Reduced implementation and maintenance cost
• Case study: a CATV operator can provide service through a HFC (wireline) network and an LMDS network (wireless) using the same infrastructure
Simultaneous wireless+wireline access results in Ubiquitous BA

ConclusionGANDALF project can provide inputs regarding:
Simultaneous wireline/wireless service provision
Coexistence of wireline and/or wireless access techniques
• GbE and Wi-Fi• DOCSIS and Wi-Fi
• Performance of wireline access techniques in wireless scenarios: - DOCSIS/wDOCSIS
• Simultaneous provision of OFDM signals in Wi-Fi and WIMAX bands- Suitability and performance of OFDM @ 40 GHz
Desired inputs from COPRAS and standardisation bodies
• Possible standardisation bodies interested in GANDALF developments• Specifications• Evolution of standards• Suitability of the activities developed in GANDALF
