OriginatorMacDataService¶

Package: inet.linklayer.ieee80211.mac.originator

compound module OriginatorMacDataService

Implements the MAC data service for the originator (sender) side in non-QoS IEEE 802.11 networks. Processes outgoing frames by assigning sequence numbers and performing fragmentation based on the configured policy. Follows the MAC data plane architecture described in IEEE 802.11 standard to prepare frames for transmission.
