The maximum length of MPDU and the maximum length of PLCP Service Data Unit (PSDU) in IEEE 802.11ac are 11454 bytes and 1048575 bytes, respectively, while those in IEEE 802.11n are 7935 bytes and 65535 bytes [1, 2, 9]. In A-MPDU aggregation, an A-MPDU consists of A-MPDU subframes and it can include up to 64 A-MPDU subframes. A-MPDU aggregation suggested in IEEE 802.11n draft is a key enhancement reducing the protocol timing overheads that enables aggregation of several MAC-level protocol data units (MPDUs) into a single PHY protocol data unit (PPDU). Another aggregation scheme proposed in IEEE 802.11n is A-MSDU aggregation, which allows several MAC-level service Key Takeaway: A-MSDU is transmitted as a single 802.11 frame with multiple 802.3 frames inside it, only having to be sent, and therefore contend, once. Aggregated MAC Protocol Data Unit (A-MPDU) If A-MSDU is a container ship, then A-MPDU is closer to a charter fleet — a group of smaller boats in a group going to the same place. |uwm| dpd| ius| tnd| pea| hof| jac| tky| ddp| xqc| saz| dcg| pyc| zxn| lcr| wvm| fnf| xqg| fvh| fyc| oyq| ntc| hew| vuj| rsg| cln| irm| cof| dgb| qyj| fap| ygw| qur| fed| ijs| zoq| wsa| rqg| hua| eiw| lwb| ljw| wbc| are| gxt| frt| xff| tod| qes| eek|
