    Intangiriro kuri WiFi Calibration Parameter

    Igihe cyo kohereza: Ukuboza-22-2022

    Ibicuruzwa bya WiFi bidusaba gupima intoki no gukuramo amakuru yimbaraga za WiFi ya buri gicuruzwa, none se ni bangahe uzi kubyerekeye ibipimo bya kalibrasi ya WiFi, reka nkumenyeshe:

    WiFi

    1. Gukwirakwiza imbaraga (TX Power): bivuga imbaraga zakazi za antenne yohereza ibicuruzwa bidafite umugozi, igice ni dBm. Imbaraga zo gukwirakwiza simusiga zigena imbaraga nintera yikimenyetso kitagira umugozi, imbaraga nini, ikimenyetso gikomeye. Mugushushanya ibicuruzwa bidafite umugozi, hazajya habaho imbaraga zintego nkibanze shusho yacu. Mugihe cyo guhaza ikibaho na EVM, uko imbaraga zohereza, niko gukora neza.
    2. Kwakira sensibilité (RX Sensitivity): Ikintu kiranga imikorere yo kwakira DUT. Nibyiza kwakira sensibilité, ibimenyetso byingirakamaro byakira, kandi nubunini bwayo butagaragara. Mugihe ugerageza kwakira sensibilité yakira, kora ibicuruzwa muburyo bwakiriwe, koresha igikoresho cya kalibrasi ya WiFi kugirango wohereze dosiye yihariye, kandi ibicuruzwa bizakira, kandi urwego rwamashanyarazi rwoherejwe rushobora guhindurwa kubikoresho bya kalibrasi ya WiFi kugeza ibicuruzwa bipfunyitse. igipimo cyamakosa (PER%) cyujuje ubuziranenge.
    3. Ikosa rya Frequency (Ikosa rya Frequency): Yerekana gutandukana kwikimenyetso cya RF kuva kumurongo wo hagati wumuyoboro aho ikimenyetso giherereye, muri PPM.
    4. Ikosa Vector Magnitude (EVM): Ni indangagaciro yo gusuzuma ubwiza bwikimenyetso cyahinduwe, kandi igice ni dB. Gitoya ya EVM, nibyiza byerekana ibimenyetso. Mubicuruzwa bidafite umugozi, imbaraga za TX na EVM bifitanye isano. Nimbaraga za TX nini, nini ya EVM, ni ukuvuga, ubwiza bwibimenyetso. Kubwibyo, mubikorwa bifatika, hagomba gukorwa ubwumvikane hagati ya TX Power na EVM.
    5. Kohereza Spectrum Mask yikimenyetso cyatanzwe irashobora gupima ubuziranenge bwikimenyetso cyatanzwe hamwe nubushobozi bwo guhagarika kwivanga kumiyoboro yegeranye. Ikirangantego cyerekana ibimenyetso biri munsi yikizamini cyujuje ibisabwa.
    6. Umuyoboro nanone witwa umuyoboro (Umuyoboro) cyangwa umurongo wa radiyo, ni umuyoboro wogukwirakwiza amakuru hamwe numuyoboro udafite insinga (electromagnetic wave) nkuwitwara. Imiyoboro idafite insinga (Routers, Hotspots za AP, amakarita ya mudasobwa idafite mudasobwa) irashobora gukora kumiyoboro myinshi. Ibikoresho bitandukanye byumuyoboro utagira umurongo mugace kegeranye nibimenyetso bidafite umugozi bigomba kugerageza gukoresha imiyoboro itandukanye kugirango wirinde kwivanga hagati yibimenyetso.
