WiFi: AMSDU vs AMPDU: A Brief Tutorial on WiFi Aggregation Support

  • WiFi MAC architecture supports aggregation at two layers. 
  • The MAC service data  units (MSDUs) can be aggregated to form AMSDUs. 
  • Each AMSDU serves as a single MAC protocol data unit (MPDU). 
  • Another layer of aggregation is introduced when MPDUs can be packed together
WiFi Aggregation 


In this brief 2 page tutorial we discuss 
(1) why aggregation is useful at all,
(2) why two layers of aggregation are useful,
(3) trade-offs for aggregating at different layers.
