    Intshayelelo kwiiParameters zoLungiso lweWiFi

    Ixesha lokuposa: Dec-22-2022

    Iimveliso zeWiFi zifuna ukuba silinganise ngesandla kwaye silungise ulwazi lwamandla eWiFi kwimveliso nganye, ke unolwazi olungakanani malunga neeparamitha zokulinganisa iWiFi, mandikwazise:

    WiFi

    1. Ukuhambisa amandla (amandla e-TX): ibhekisela kumandla okusebenza kwe-antenna yokuhambisa imveliso engenazintambo, iyunithi i-dBm. Amandla othumelo olungenacingo lumisela amandla kunye nomgama wesignali engenazingcingo, amandla amakhulu, amandla omqondiso. Kuyilo lwemveliso engenazingcingo, kuya kuhlala kukho amandla ekujoliswe kuwo njengesiseko soyilo lwethu. Ngaphantsi kwesiseko sokwanelisa ibhodi ye-spectrum kunye ne-EVM, amandla amakhulu okuhambisa, ngcono ukusebenza.
    2. Ukufumana uvakalelo (i-RX Sensitivity): Iparamitha ebonisa ukusebenza kokufumana kwe-DUT. Okukhona ifumana ubuntununtunu, kokukhona iluncedo ngakumbi imiqondiso eyifumanayo, kwaye kokukhona igubungele ngaphandle kwamacingo. Xa uvavanya uvakalelo lokufumana, yenza imveliso kwimeko yokufumana, sebenzisa isixhobo sokulinganisa i-WiFi ukuthumela ifayile ethile ye-waveform, kwaye imveliso iya kuyifumana, kwaye inqanaba lamandla elithunyelwe linokuguqulwa kwisixhobo sokulinganisa i-WiFi de ipakethe yemveliso. izinga lemposiso (PER%) idibana nomgangatho .
    3. Imposiso yeFrequency (Imposiso yeFrequency): Imele ukutenxa kophawu lweRF ukusuka kumbindi wejelo apho umqondiso ukhoyo, kwiPPM.
    4. I-Error Vector Magnitude (EVM): Sisalathiso sokuqwalasela umgangatho wesignali ehlengahlengisiweyo, kwaye iyunithi yi-dB. Incinci i-EVM, ingcono umgangatho wesignali. Kwimveliso engenazingcingo, amandla e-TX kunye ne-EVM zinxulumene. Ubukhulu be-TX Amandla, i-EVM enkulu, oko kukuthi, umgangatho wesignali ubi kakhulu. Ngoko ke, kwizicelo ezisebenzayo, ukuhambelana kufuneka kwenziwe phakathi kweTX Power kunye ne-EVM.
    5. I-Transmit Spectrum Mask yesiginali edlulisiweyo inokulinganisa umgangatho wesignali edlulisiweyo kunye nokukwazi ukucinezela ukuphazamiseka kumajelo akufutshane. Imaski ye-spectrum yesiginali phantsi kovavanyo ifanelekile ngaphakathi kwe-mask ye-spectrum esemgangathweni.
    6. Ijelo likwabizwa ngokuba yitshaneli (iChaneli) okanye ibhendi yamaza, eyijelo losasazo lwesignali yedatha enesignali engenacingo (i-electromagnetic wave) njengomthuthi wothumelo. Inethiwekhi ezingenazingcingo (iirotha, I-AP hotspots, amakhadi angenantambo ekhompyutheni) inokusebenza kwiitshaneli ezininzi. Izixhobo zothungelwano ezingasebenzi ngeengcingo ngaphakathi kwendawo yokhuselo lweesignali ezingenazingcingo kufuneka zizame ukusebenzisa amajelo ahlukeneyo ukuthintela ukuphazamiseka phakathi kweempawu.
