Create a Wireless Link between two nodes in ns3 - c++

Question

I have to build a topology where 2 nodes are connected via the wifi network or cellular network.
In ns-3 I can't find examples to do so.
How could I build the topology ?

Answer 1

NS3 has only 4G network modules, WiMax and LTE. NS3 has no 2G or 3G modules.
Here is the example to create topology of a source node sending UDP packet to a sink node with combination of cellular network and Wifi Network.
