- 9 years in wireless communication projects and SDR projects (high-end)
- 3 years experience with (cheap) SDR's
RADIO
The science (magic) of translating a message
to electromagnetic waves
and back
So...what is a
software-defined radio?
"Radio in which some or all of the physical layer functions are software defined"
"Traditional" radio communication system
WHO\FOR WHAT?
- Learn radio!
- Make (awesome) wireless projects!
- Security researchers
- Academy research (e.g mobile networks)
- Rapid prototyping
TYPICAL CONFIGURATION
- 150Khz - 6Ghz
- 8-16 BIT ADC, 2-60MSPS
- DR ~40dB, SENSITIVITY ~-90dBm
-
COMMERCIAL IF BANDS:
- WIFI
- WIMAX
- DVB-T (!)
- USB 2 (DONGLE \ MICRO-USB F)
Popular SDR's

And the list goes on and on...
Cool Projects
GETTING SATELLITE IMAGES
METEOR-M2 WEATHER SATELLITE
QPSK @ 137Mhz
Passive Radar
2 Log-periodic antennas
Physical synchronization
Unintentional EM emissions
1.6-1.78 MHz
MONITORING SURVEILLANCE AIRCRAFT \ SPECIAL FORCES
ADS-B - 1090Mhz
TRACKING FLIGHTS ON THE WORLD ECONOMIC FORUM
ADS-B - 1090Mhz
DRIVE TESTS
JUST A FEW MORE WORDS...
AIRPROBE - Former GSM-Sniffer project
Goal is to build an air-interface analysis tool for the GSM (and possible later 3G) mobile phone standard
GR-GSM - packs AIRPROBE with some more goodies + more friendly interface
Also - Kali-Linux and Pentoo
OPEN DISCUSSION:
