Detailed Description

Make it easy to create and manage PHY objects for the spectrum model.

The Pcap and ASCII traces generated by the EnableAscii and EnablePcap methods defined in this class correspond to PHY-level traces and come to us via WifiPhyHelper

This helper will install an instance of a WifiBandwidthFilter on any SpectrumChannel added to this helper (via one of the SetChannel methods), unless one has previously been installed on the channel object.

◆ AddChannel() [1/2]

void ns3::SpectrumWifiPhyHelper::AddChannel	(	const Ptr< SpectrumChannel >	channel,

Parameters

channel	the spectrum channel to add to this helper
freqRange	the frequency range, bounded by a minFrequency and a maxFrequency in MHz

Every PHY created by a call to Install is added to this spectrum channel. If a PHY is requested to operate or scan a channel with the specified frequency and width combination, it will activate that channel and deactivate the current channel for that PHY.
