void ns3::LteEnbPhy::DoDispose ( void )

virtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

/NodeList/[i]/DeviceList/[i]/$ns3::LteNetDevice/$ns3::LteEnbNetDevice/LteEnbPhy

Attributes defined for this type:

TxPower: Transmission power in dBm
- Set with class: ns3::DoubleValue
- Underlying type: double -1.79769e+308:1.79769e+308
- Initial value: 30
- Flags: construct write read
NoiseFigure: Loss (dB) in the Signal-to-Noise-Ratio due to non-idealities in the receiver. According to Wikipedia (http://en.wikipedia.org/wiki/Noise_figure), this is "the difference in decibels (dB) between the noise output of the actual receiver to the noise output of an ideal receiver with the same overall gain and bandwidth when the receivers are connected to sources at the standard noise temperature T0." In this model, we consider T0 = 290K.
- Set with class: ns3::DoubleValue
- Underlying type: double -1.79769e+308:1.79769e+308
- Initial value: 5
- Flags: construct write read
MacToChannelDelay: The delay in TTI units that occurs between a scheduling decision in the MAC and the actual start of the transmission by the PHY. This is intended to be used to model the latency of real PHY and MAC implementations.
- Set with class: ns3::UintegerValue
- Underlying type: uint8_t 0:255
- Initial value: 2
- Flags: construct write read
