int Mac80211MultiChannel::getChannel

(

)

Returns the currently used channel.

Returns:

The currently used channel.

References MacToPhyInterface::getCurrentRadioChannel(), and BaseMacLayer::phy.

                                     {
  return phy->getCurrentRadioChannel();
}

void Mac80211MultiChannel::initialize

(

int

stage

)

[protected, virtual]

Initialization of the module and some variables.

First we have to initialize the module from which we derived ours, in this case BaseLayer.

Reimplemented from Mac80211.

Definition at line 23 of file Mac80211MultiChannel.cc.

{
    Mac80211::initialize(stage);

    if(stage == 0) {
    }
    else if(stage == 1) {
    }
}

void Mac80211MultiChannel::switchChannel

(

int

channel

)

Tells the MAC layer to switch to the passed channel.

This method can be used by upper layers to change the channel.

Parameters:

channel

The channel to switch to, must be 1<=channel<=14.

                                                    {
  if(!(1 <= channel && channel <= 14)) {
    opp_error("Invalid channel %d. Mac tried to switch to a channel not"
          " supported by this protocoll.", channel);
  }
  phy->setCurrentRadioChannel(channel);

  centerFreq = CENTER_FREQUENCIES[channel];
}
