2 ORBIT Cognitive Capable Platforms USRP RICE WARP Platform U. Of Colorado USRP2 GENI CRKit WINC2R System

3 Cognitive Experiments at Scale ORBIT radio grid testbed currently supports ~22/USRP and USRP2 (GNU) radios, 100 low-cost spectrum sensors, WARP and GENI platforms Plan to reach ~64 cognitive radio nodes (Q242011) Suburban ORBIT Radio Grid 500 meters Office 20 meters Urban Current ORBIT sandbox with GNU radio 30 meters 300 meters Radio Mapping Concept for ORBIT Emulator 400-node Radio Grid Facility at Tech Center Programmable ORBIT radio node URSP CR board

4 Cognitive Radio Kit (CR Kit) Open Source Platform GENI CR Kit Range of COTS baseband FPGA platforms Medium size (LX50) Large size (SX95) Standard interfaces: 1000 BaseT, (SFP) USB (8x PCIExpress) 4 (2) configurable radio modules (phased or smart antenna capable): SDR 25 MHz, ISM WDR 25 MHz, 0-7 GHz XDR 500 MHz, 0-7 GHz Application framework with support for both RTL and Matlab (Simulink)

5 WDR RF Front-end (Curr: WDR v2.02) 14 layer PCB with high-frequency 5.5 mil thick NELCO N material 6000 part footprints with more than 4800 parts One to four independent radio modules on one (FPGA) processor. Each module allows two up to 40 MHz bands from 100 to 7500 MHz 12 bit ADC sampling up to 80MSps on both I and Q rails. NF = 6dB, optional external LNA for customized applications. 70dB of RX gain control. 14 bit DAC sampling upto 200MSps on both I and Q rails. +20dBm TX output power with fast gain control. 60 db of TX gain control Supports full duplex operation. 1 usec RF frequency switching time Switched antenna diversity for both TX and RX channels Comprehensive reference clock selection or generation with internal, external or digitally derived sample clocks. Extensive built-in-test for monitoring system status and health (including loopback).

6 CR Kit Framework Features Fully functional FPGA development platform with pluggable user applications. Two environments: MATLAB/Simulink or VHDL/Verilog/BlueSpec Communication with host using GbE links Streamlined FPGA building process e.g. HW design made-easy using MATLAB/Simulink and build scripts.

7 CR Kit User Applications APP subsystem: Build App as separate entity in MATLAB/Simulink, then integrate into Framework. Integration of Tx and Rx subsystems Well-defined IO interfaces between APP and Framework. Either develop own Tx/Rx Apps, or select from libraries

8 CRKit Future Plans Conversion of waveform to more modular form (BlueSpec) Validation of waveform control across wideband front-end Further development of basic communication blocks (GENI Radio Library) Multi-FPGA support and design partitioning Wider GENI deployment 8

9 GENI The Global Environment for Network Innovations (GENI) is a nation-wide infrastructure being designed, developed and deployed to support experimental research in network science and engineering. Networks are broadly defined with multiple layers of abstraction, from physical substrates, through the architecture and protocols, to networks of people, organizations, and societies GENI - htp://

10 GENI: Infrastructure For At-Scale Experimentation GENI - htp:// GENI-enabled at-scale infrastructure Deeply programmable Virtualized Programmable & federated, with end-to-end virtualized slices Sensor Network GENIenabled at-scale infrastructur e Federated International Infrastructure Heterogeneous, and evolving over time via spiral development Mobile Wireless Network Edge Site

11 GENI: Spiral Development GENI grows through a well-structured, adaptive process Spiral Development Process Re-evaluate goals and technologies yearly by a systematic process, decide what to prototype and build next. Use Use Integration Planning Build out GENI Prototyping Plan Design GENI - htp:// GENI Spiral 3 Early experiments, meso-scale build, interoperable control frameworks, ongoing integration, system designs for security and instrumentation, definition of identity management plans. Envisioned ultimate goal Example: Planning Group s desired GENI suite, probably trimmed some ways and expanded others. Incorporates large-scale distributed computing resources, high-speed backbone nodes, nationwide optical networks, wireless & sensor nets, etc.
