Ettus Research founded in 2004 Acquired by National Instruments in Feb 2010 Now operating as a wholly-owned subsidiary Based in Mountain View, CA Currently 10 employees
Business Model Sell low-cost, easy to use software radio kits Build a community of users Keep a very low overhead Fit into the niche between consumer-level and test equipment level price and performance Engineering Model Use mid-sized, low-cost FPGAs Allow user to reprogram, build o of our open-source IP Leverage from, and give back to the Open Source community Rapid design turnaround, keep up with the latest chips and capabilities Use highly-integrated parts where possible Universal drivers allow use with any software stack
Outline 1 2 3 4
Goals Very low cost Interchangeable RF sections Wide bandwidth Extreme exibility MIMO-capability Create a community of user-developers Developed in parallel with GNU Radio Don't constrain what the user does
Architecture USRP Motherboard interfaces computer to analog Bus or network interface to host FPGA Dual high-speed ADCs and DACs for Quadrature signals Low speed ADCs and DACs for RSSI, gain ctrl, etc. Clock generation GPIOs, I2C, SPI Interchangeable daughterboards convert analog baseband to RF Quadrature Up/Downconverters VCO/PLL for LO LNA, PA, all ltering
Universal Hardware Driver (UHD)
UHD Works on Linux, Mac, Windows Using CMAKE for cross-platform build system Windows build with Visual Studio, Cygwin, MinGW LabVIEW, Simulink, GNU Radio, OpenBTS, and OSSIE all support UHD now Supports all of our hardware transparently Dual-license model (GPL + Other) Handles arbitrary MIMO congurations
FPGA Design Digital up- and downconverters CORDIC algorithm Decimation and Interpolation CIC and halfband lters Data formatting, packetizing, and bus interfacing Daughterboard Control Precise timing Room for user expansion

USRP E100
USRP Embedded Highlights Runs REAL Linux No need to choose between GPP, DSP, or FPGA processing Can develop directly on E100/E110 Develop on desktop with USRP1/2/N210, deploy (same code!) on Embedded Uses UHD Low power, no laptop Low latency with direct bus access
Embedded Usage Model Network testbeds Wireless sensor nodes Public safety nodes Picocells Low-cost SIGINT boxes
