UWBIRMac (simple module)

This class provides helper function for MAC modules that use the UWB-IR IEEE 802.15.4A model. Just before sending down a packet to the UWBIRPhyLayer, call prepareData(UWBIRMacPkt* packet). Just after receiving a packet from the UWBIRPhyLayer, call validatePacket(UWBIRMacPkt* packet) and check the returned bool value to know if the packet could be decoded successfully.

Used in compound modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.
