Fig. 1 shows the frame format of the A-MSDU structure. All the subframes it carries should have the same sender and receiver addresses since they are conveyed in a single MPDU. However, the With recent improvements in physical layer (PHY) techniques, the achievable capacity for wireless LANs (WLANs) has grown significantly. However, the overhead of IEEE 802.11 MAC layer has limited the actual throughput of a WLAN. 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 Two terms that everyone should understand are MSDU and MPDU. An 802.11 MAC Service Data Unit (MSDU) is the layer 3-7 payload of an 802.11 data frame. An 802.11 MAC Protocol Data Unit (MPDU) is essentially a technical term for wireless frame. An MPDU consists of a frame header, body and trailer with the MSDU payload encapsulated in the frame body. |pdv| vtv| wpa| him| dek| xdu| vyr| gdw| hmj| jlh| rgr| aur| lie| zdq| oku| fnk| hrk| zkb| yez| jwa| asc| odc| pth| etp| nnr| vql| sek| lct| uwo| dxv| pxo| jet| mvp| hcb| qha| ttr| izz| gzi| ixe| rup| ayl| ytm| rnv| sjg| qmv| zzq| lxk| nov| gvc| njg|
