Hello,

Would like to confirm if the carrier frequency (EARFCN) in the LteEnbNetDevice class is in Hz, so the following lines would set downlink and uplink EARFCN to 2500Hz? and if I don't set a value, what's the default setting?

Config::SetDefault ("ns3::LteEnbNetDevice::DlEarfcn", UintegerValue (2500));

Config::SetDefault ("ns3::LteEnbNetDevice::UlEarfcn", UintegerValue (2500));

Thank you!

No. The erafcn is the channel number, so for 2500MHz the equivalent is 39690 and most likely would be TDD in that band.
