* Free and Open Source Software
 * typically strong in infrastructure and embedded
 * Linux to be found in many unexpected places today
 * [various examples]
* Benefits of FOSS
 * reduced "software BOM" cost
 * joint development resources leading to less R&D cost at each
   individual user (compared to custom implementation)
 * more eyes reviewing code than any organization has developers in-house

* existing community-driven FOSS projects
 * gnuradio
  * do SDR on x86, use C++ blocks connected by python scripts
  * GUI for visually creating signal processing flow-graphs
  * strength in research and prototyping of SDR applications
 * OpenBTS
 * airprobe
  * GSM receiver for protocol analysis
 * Osmocom (TETRA, GMR, SDR, ...)

* inexpensive SDR hardware
 * USRP family (>= USD 1000)
 * OsmoSDR (USD 200)
  * receive-only, 1.4 Ms/s @ 14bit (HW v3: 4.2 Ms/s)
  * 64 MHz ... 2 GHz
  * small FPGA + Cortex-M3
 * rtl-sdr (USD 20)
  * 64 MHz ... 2 GHz
  * ?? Ms/s @ 8 bit
  * raw samples 
 * UmTRX

* inexpensive "low-end" SDR hardware + FOSS go hand in hand
 * enable participation in research and development to anyone with sufficient time and interest
   * beyond traditional telecom industry
   * beyond top-tier universities with large research grants
   * removes entry barriers
   * small businesses can innovate and participate in the market

* accessibility of technology
 * UFPA / Brazil
 * ENSPT / Yaounde

* slides from "FOSS in telco / security"

* what can the industry get from this?
 * ennabling students, researchers and hobbyists to experiment and build skills (whihc are
