  7. KEY ISSUES • Identification of future end-user services and specification of network requirements • Upgrade strategies for next generation PONs and AONs for access networks • Technical and economical issues for in-building networks based on optical fibers • Integration of wireless signal transport in access and in-building networks • Optimal use of network resources in access and in-building scenarios (dynamic capacity allocation) • Reliable and cost-efficient technologies for high-speed transmission over multi-mode and plastic optical fibre • Management and control for ubiquitous quality of service • Integration and validation of project solutions in the project testbeds

  8. TECHNICAL APPROACH • Starts with analyzing future bandwidth and QoS requirements • Access and in building networks • Optical layer dynamics, compatibility of network types at • the physical layer • Foundations for better QoS provisioning and embedding of 2G/3G and B3G signals into the networks • The project pursues experimental validations of close-to-maturity technologies in laboratory tests and field trials by intensively exploiting the three project test beds. The project also includes long-term research activities targeting to improve the existing technologies, and follows an intensive dissemination and standardization strategy.

  17. ALPHA • Access Network • In building Network • Physical Technology • Modulation Techniques • Demonstration and Field Trials • Project Test Beds • Conclusion

  18. ACCESS NETWORKS • Optical Fiber is used to transport and distribute multi service signals while offering transparency and flexibility • Passive Optical Networks (PON) topologies have been the basic architectures emerging as low cost solutions for optical communication systems • Wavelength Division Multiplexing, Dynamic Wavelength Assignment, Development of agile Optical Component Modules and Survivable Networking have extended the capabilities of basic Broadband Passive Optical Networks • Reallocation of wavelength channels was performed by flexible wavelength router based on Thermo-optic Mach-Zehnder Switches • Dynamic Wavelength Allocation (DWA) has been demonstrated to provide bandwidth sharing across multiple physical PONs

  19. IN-BUILDING NETWORKS • Deploy higher carrier frequencies, implying radio pico-cells and multiple antenna systems (MIMO) • Radio-over-Fibre solutions can help to consolidate signal processing at a central station (CS) and reduce antenna site cost • Next generation user terminals will require multiple Gbit/s data interfaces for fast and reliable data transfer • Aim of ALPHA project is to get a unified and coverage in-building infrastructure, which offers a common platform for all existing and foreseeable future services. • Such infrastructure should be broadband and offer the opportunity to transport services of widely varying signal characteristics and QoS.

  20. IN-BUILDING NETWORKS

  21. PHY Technologies • ALPHA targets to implement the transmission solutions that can guarantee the required bit rate regardless the available physical media • Efforts are now been made to extend access networks to higher bit rates such as aggregate 10 Gbps • Optical fibres are recognized good for access network and increasing the upstream capacity favors the fibre based access even more • For in-building networks and especially for home networks using multimode and plastic optical fibres gives a substantial bandwidth and saving on the equipment compared to single mode fibre mode solutions

  22. MODULATION TECHNIQUES • Wavelength Division Multiplexing (WDm) with wavelengths modulated at a bit rate of 10 Gbps • Non Return-to-zero (NRZ) modulation • Amplitude Shift Keying (ASK) • Carrier Suppressed Return to Zero (CSRZ) On Off Keying (OOK) • Alternate Phase Return to Zero (APRZ)-OOK • QAM • PSK • OFDM

  23. Demonstration & Field Trials • Goal of ALPHA project will be pursued by creating a versatile development and complex test environment that will be used to access architectural and transmission solution proposed in other work packages. • This environment will be based on three project test beds that will be used to access the network solution under investigation:

  24. PROJECT TEST BEDS • HOME NETWORK MULTI SERVICE NETWORK France Telecom/Orange Labs home network multi-service test-bed interconnected (within the project) with the Alcatel-Lucent Bell Labs Access Network test-bed in France using 10 Gb/s WDM Ethernet PON and analogue Radio-over-Fibre technologies. • ACCESS HOME TEST BED Access-Home test-bed at Acreo in Sweden with a mixed fibre-based physical layer and independent test-pilots. 3. HOME NETWORK TEST BED Home Network testbed at Telefonica in Spain based on mixed physical layer technologies and with the support of femto-nodes.

  25. CONCLUSION • Main goal of ALPHA project is to investigate new architecture and transmission solutions for future coverage access and in building networks providing support to both wired and wireless services and according to end users future services requirements • Due Date of Submission : Dec 31, 2008 • Actual Date of Submission: Jan 13, 2009 • Duration: 36 months
