Detailed Description

This helper class allows to easily create a topology with eNBs grouped in three-sector sites laid out on an hexagonal grid.

The layout is done row-wise.

Member Function Documentation

◆ DoDispose()

void ns3::LteHexGridEnbTopologyHelper::DoDispose ( )

overridevirtual

Destructor implementation.

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

Subclasses are expected to implement their real destruction code in an overridden 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.

Reimplemented from ns3::Object.

Here is the call graph for this function:

◆ GetTypeId()

TypeId ns3::LteHexGridEnbTopologyHelper::GetTypeId ( )

static

Register this type.

Returns: The object TypeId.

Here is the call graph for this function:

◆ SetLteHelper()

void ns3::LteHexGridEnbTopologyHelper::SetLteHelper ( Ptr< LteHelper > h )

Set the LteHelper to be used to actually create the EnbNetDevices.

Note: if no EpcHelper is ever set, then LteHexGridEnbTopologyHelper will default to creating an LTE-only simulation with no EPC, using LteRlcSm as the RLC model, and without supporting any IP networking. In other words, it will be a radio-level simulation involving only LTE PHY and MAC and the FF Scheduler, with a saturation traffic model for the RLC.
