    Isendlalelo Sesixhumanisi Sedatha ye-WLAN

    Isikhathi sokuthumela: Oct-26-2022

    Isendlalelo sesixhumanisi sedatha se-WLAN sisetshenziswa njengesendlalelo esiyinhloko sokudluliswa kwedatha. Ukuze uqonde i-WLAN, udinga futhi ukuyazi ngokuningiliziwe. Ngezincazelo ezilandelayo:
    Kuphrothokholi ye-IEEE 802.11, isisekelo sayo se-MAC siqukethe izindlela zokufinyelela zemidiya ze-DCF ne-PCF:
    Incazelo ye-DCF: Umsebenzi Wokuxhumanisa Okusabalalisa
    Nakuba i-DCF iyindlela yokufinyelela eyisisekelo ye-IEEE 802.11 MAC, esebenzisa ubuchwepheshe be-CSMA/CA futhi ingeyendlela yokuncintisana, lapho le nodi ithumela idatha, izoqapha isiteshi. Kuphela uma isiteshi singenzi lutho singathumela idatha. Uma isiteshi singenzi lutho, indawo izolinda isikhathi esinqunyiwe phakathi kwe-DIFS.
    Uma ukudluliswa kwamanye amanodi kungezwakali ngaphambi kokuphela kwe-DIFS, kubalwa isikhathi sokubuyela emuva okungahleliwe, esilingana nokusetha isibali-sikhathi sokubuyela emuva;
    I-node ithola isiteshi ngaso sonke isikhathi lapho ihlangabezana nesikhathi: uma ithola ukuthi isiteshi asisebenzi, isibali-sikhathi sokubuyela emuva siyaqhubeka nesikhathi; uma kungenjalo, isikhathi esisele sesibali-sikhathi esingemuva siqandisiwe, futhi i-node ilinda futhi ukuze isiteshi singasebenzi; ngemva kokudlula kwe-DIFS, i-node iyaqhubeka nokubala yehle kusukela esikhathini esisele; Uma isikhathi sesibali-sikhathi esibuyela emuva sincipha sibe yiziro, lonke uhlaka lwedatha luzothunyelwa. Lena inqubo yokulungisa yokudluliswa kwedatha.
    I-PCF: Umsebenzi Wokuxhumanisa Iphoyinti;
    I-PCF ihlinzeka ngomxhumanisi wephoyinti ukuze enze inhlolovo kuwo wonke amasayithi okuthumela noma ukwamukela idatha. Lena indlela engancintisani, ngakho ukushayisana kozimele ngeke kwenzeke, kodwa kungasetshenziswa kuphela kumanethiwekhi wendawo angenantambo anengqalasizinda ethile.
    Okungenhla ukwethulwa kwe-WLAN Data Link Layer elethwa i-Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. I-Shenzhen HDV Phoelectron Technology Co., Ltd. ingumkhiqizi ochwepheshe bemishini yokuxhumana yokukhanya, kanye nokuxhumana kwayo.imikhiqizo.
