  2. MISSION CTTC is a private R&D center resulting from a public initiative (Generalitat Catalunya) legally established in 2001 as a non-profit foundation. • Excellence center to lead long-term research and engineering projects • Play a new role in R&D training: • Pre- and post-doc levels • Complementary to existing R&D infrastructure • Fill the industry-academia gap • Pre-competitive R&D partner • Increased number of researchers • Establishment of industrial R&D

  3. ORGANIZATION Council Auditors Executive Commission Scientific Advisory Committee International Relations Direction Institutional Relations Business Advisory Committee Technology Transfer Supporting Services Engineering Research Administration Private Non Profit Foundation Accounting/ Adm. Controlling Radio Communications Communications Access Technologies Administrative Management Equipment/Labs Optical Networking Personnel Library Communications Subsystems Maintenance IP Technologies

  5. OUR TESTBEDS IN A NETWORK CONTEXT GEDOMIS:Reconfigurable MIMO platform LINK

  6. Antenna subsystem: adjustable linear array. RF/IF Front-End: Multi-band (2.4 & 5.2 GHz) multi-channel (4 ch Tx or 4 ch Rx). • IF block: • Tx: digital IF generation: high-speed 4-channel DAC module • Rx: IF undersampling 2x high-speed 2-channel ADC modules. • Baseband Processing: DSP and FPGA mother-boards. GEDOMIS: Reconfigurable MIMO platform 4x4 MIMO testbed

  7. GEDOMIS: Reconfigurable MIMO platform • Current usage in funded R&D projects: • EUREKA-MARQUIS - Multi-Antenna tRansceivers for QoS, Ubiquitous and Improved wireless Systems. • Potential activities within Research Networking Testbeds projects: • Implementation of physical and link layer algorithms: • Space-time processing, antenna selection schemes,... • MAC and Scheduling • Synchronization in MIMO-OFDM systems • MIMO channel estimation aIgorithms • Power allocation strategies • ... • Performance evaluation with impairments or realistic channel conditions • Partial/full channel state information (CSI) • Limited accuracy in estimated CSI: impact on diversity/multiplexing gains • Flat/frequency-selective channels • Correlated fading (antenna separation) • Finite RF isolation • ...

  8. EXTREME:IP over wireless OUR TESTBEDS IN A NETWORK CONTEXT ACCESS NETWORK

  9. CTTC Production network Remote Management Station Other testbeds WLAN Antenna DATA DATA SWITCH ROUTER Internet CONTROL CONTROL GPS Antenna WLAN Antenna SERVER NETWORK NODES Routers – Switches – Measurement equipment … COMMERCIAL EQUIPMENT EXTREME: IP over wireless Mobile nodes: Equipped with 802.11 WLAN cards Switch-router: reconfigurable patch-panel Server: OS images, NTP, DHCP, console manager Network nodes: 24, identical (same hardware) • So, why EXTREME? • Reduction of time from scenario conception to availability for tests. • Flexibility in the tested architectures

  10. EXTREME: IP over wireless • Current usage in funded R&D projects: • FREEDOM: Contract with mobile operator AMENA (peer-to-peer, open spectrum, VoIP) • Potential activities within Research Networking Testbeds projects: • Wireless measurements and monitoring: • Network: Throughput, delay, delay jitter, packet losses,... • Applications: e.g. VoIP E-model • Testing: • Mobility: Network layer vs. application layer mobility • Characterization of the handover process (horizontal, vertical) • VoIP over wired and wireless networks • Simulations/emulations: • Router autoconfiguration • Wireless mesh networks • Emulation/monitoring: e2e (edge+core) testbed in collaboration with CTTC’s ADRENALINE testbed.
