Energy Detection Threshold Wifi

[Dasha Sayed]

Hi. I would like to know where i can modify the energy detection threshold of wifi in the LAA module. I know the value is set up to -62 dBm but I'm not sure where I can change it. Thanks in advance for your help!

Hi,

Please refer to the attributes of the SpectrumWifiPhy class. For setting/configuring attributes, see the manual.

• EnergyDetectionThreshold: The energy of a received signal should be higher than this threshold (dbm) to allow the PHY layer to detect the signal.
  • Set with class: ns3::DoubleValue
  • Underlying type: double -1.79769e+308:1.79769e+308
  • Initial value: -96
  • Flags: construct write read

Regards

Hello,

Konstantinos' comment is related to ns-3-dev branch. In the branch containing LAA feature, this attribute is named CcaMode1Threshold (see SpectrumWifiPhy::GetTypeId). You can set it exactly the same way.
