Current ORBIT sandbox with GNU radio
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)
WINLAB
Cognitive Radio Kit (CR Kit)
GENI CR Kit
Open Source Platform
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)
WINLAB
WDR RF Front-end (Curr: WDR v2.02) 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).
• 14 layer PCB with high-frequency 5.5 mil thick NELCO N4000-13 material• 6000 part footprints with more than 4800 parts
WINLAB
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.
WINLAB
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
WINLAB8
CRKit Future Plans
Conversion of waveform to more modular form (BlueSpec)
Validation of waveform control across wide-band front-end
Further development of basic communication blocks (GENI Radio Library)
Multi-FPGA support and design partitioning Wider GENI deployment
WINLAB
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

Use
• GENI Spiral 3Early experiments, meso-scale build, interoperable control frameworks, ongoing integration, system designs for security and instrumentation, definition of identity management plans.
• Envisioned ultimate goalExample: 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.
GENI grows through a well-structured, adaptive processSpiral Development Process
Re-evaluate goals and technologies yearly by a systematic process, decide what to prototype and build next.
