Spirent iGEN Interference Generator
Generates common sources of interference

Generates traffic or waveform interference, enabling throughput and other wireless tests in the presence of interference.

Generates 802.11a/b/g/n/ac traffic and common sources of interference, including Bluetooth and radar waveforms for DFS testing; supports 802.11p band to test Wi-Fi/DSRC coexistence.

The OCTOBOX iGEN interference generator creates realistic interference conditions for testing wireless devices and systems. iGEN supports 802.11a/b/ g/n/ac with the ability to generate traffic or waveform interference in the 2.4 and 5 GHz bands, including in the licensed DSRC (direct short range communications) band to test coexistence between Wi-Fi and automotive networks. Waveform interference includes tones or radar waveforms for DFS (dynamic frequency selection) testing.

  • 802.11a/b/g/n/ac traffic generation in the 2.4 or 5 GHz band, including the licensed DSRC band
  • 20, 40 and 80 MHz wide channels
  • Replay traffic captures (PCAP files) with configurable traffic load and priority
  • 2 GB of storage for captures; supports standard Wireshark PCAP format files
  • Programmable channel frequency, channel width (20, 40, 80 MHz), MCS (modulation coding scheme) and WMM (wireless multi media) priority
  • Built-in frequency synthesizer for generating On/Off Keying waveforms in the frequency range of 500 to 6000 MHz
  • Built-in programmable attenuator: 60 dB range, 0.5 dB steps
  • Convenient single cable Ethernet/ PoE power and control interface, filtered for isolation
  • DSRC and Wi-Fi coexistence


  • Wi-Fi (802.11a/b/g/p/n/ac), Bluetooth and cellular testing in the presence of interference
  • DFS (802.11h) functional testing
  • Throughput vs. range measurements under interference conditions using OCTOBOX testbed
  • Adjacent channel interference (ACI)
  • Co-channel interference (CCI)
  • RX interference handling
