    Kuyambitsa kwa WiFi Calibration Parameters

    Nthawi yotumiza: Dec-22-2022

    Zogulitsa za WiFi zimafuna kuti tiziyesa pamanja ndikuchotsa chidziwitso chamagetsi a WiFi pachinthu chilichonse, ndiye kuti mumadziwa zingati za magawo a kusanja kwa WiFi, ndiroleni ndikudziwitseni:

    Wifi

    1. Mphamvu yotumizira (TX Power): imatanthawuza mphamvu yogwira ntchito ya antenna yotumizira mankhwala opanda waya, unit ndi dBm. Mphamvu yotumizira opanda zingwe imatsimikizira mphamvu ndi mtunda wa siginecha yopanda zingwe, mphamvu yayikulu, chizindikiro champhamvu. Pakupanga kwazinthu zopanda zingwe, nthawi zonse padzakhala mphamvu yowunikira ngati maziko a mapangidwe athu. Pansi pamalingaliro okhutiritsa bolodi la sipekitiramu ndi EVM, kukulitsa mphamvu yotumizira, kumagwira ntchito bwino.
    2. Kulandira sensitivity (RX Sensitivity): Chizindikiro chomwe chimasonyeza kulandila kwa DUT. Kulandila kwabwinoko, kumalandila ma siginecha othandiza kwambiri, komanso kufalikira kwake kopanda zingwe. Mukayesa kukhudzika komwe mumalandira, pangani zomwe mumalandira, gwiritsani ntchito chipangizo chowongolera cha WiFi kuti mutumize fayilo inayake, ndipo chinthucho chidzalandira, ndipo mulingo wamagetsi womwe umatumizidwa ukhoza kusinthidwa pa chipangizo cha WiFi calibration mpaka paketi yazinthuzo. kuchuluka kwa zolakwika (PER%) kumakwaniritsa mulingo .
    3. Kulakwitsa Kwafupipafupi (Frequency Error): Zimayimira kupatuka kwa chizindikiro cha RF kuchokera kufupipafupi pakati pa njira yomwe chizindikirocho chili, mu PPM.
    4. Vuto la Vector Magnitude (EVM): Ndilolozera kuti muganizire za mtundu wa chizindikiro chosinthidwa, ndipo unit ndi dB. EVM yaying'ono, imakhala yabwinoko chizindikiro cha chizindikiro. Pazinthu zopanda zingwe, mphamvu za TX ndi EVM zimagwirizana. Kuchuluka kwa Mphamvu ya TX, EVM yaikulu, ndiko kuti, khalidwe loipa kwambiri la chizindikiro. Chifukwa chake, pazogwiritsa ntchito, kusagwirizana kuyenera kupangidwa pakati pa TX Power ndi EVM.
    5. Transmit Spectrum Mask ya chizindikiro chopatsirana imatha kuyeza mtundu wa chizindikiro chopatsirana komanso kuthekera koletsa kusokoneza kwa njira zoyandikana. Chigoba cha sipekitiramu ya chizindikiro chomwe chikuyesedwa chimakhala choyenerera mkati mwa chigoba chodziwika bwino.
    6. Njirayi imatchedwanso njira (Channel) kapena frequency band, yomwe ndi njira yotumizira ma data yokhala ndi ma waya opanda zingwe (electromagnetic wave) ngati chonyamulira chotumizira. Ma network opanda zingwe (ma routers, AP hotspots, makhadi opanda zingwe apakompyuta) amatha kugwira ntchito panjira zingapo. Zida zosiyanasiyana zama netiweki opanda zingwe zomwe zili m'malo ofikira ma siginecha opanda zingwe zikuyenera kuyesa kugwiritsa ntchito ma tchanelo osiyanasiyana kupewa kusokoneza ma siginecha.
