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.
+ high-bandwidth capabilities (GHz/Gbps range)
+ cost-reduction (required O/E bandwidth, highly integrated BS approach)
Requires identification of data formats/access techniques suitable for simultaneous transmission via wireline and wireless access networks.
Laboratory and small field trial demostrating simultaneous and interoperable wireless and wireline transmissions.

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
