    Isingeniso se-WiFi Calibration Parameters

    Isikhathi sokuthumela: Dec-22-2022

    Imikhiqizo ye-WiFi idinga ukuthi silinganisele mathupha futhi silungise imininingwane yamandla e-WiFi yomkhiqizo ngamunye, ngakho-ke kungakanani okwaziyo ngamapharamitha wokulinganiswa kwe-WiFi, ake ngikwazise kuwe:

    I-WiFi

    1. Amandla okudlulisa (amandla e-TX): ibhekisela emandleni okusebenza othi oludlulisayo lomkhiqizo ongenazintambo, iyunithi i-dBm. Amandla okudlulisa okungenantambo anquma amandla nebanga lesiginali engenantambo, amandla amakhulu, isignali inamandla. Kumklamo womkhiqizo ongenazintambo, kuzohlala kukhona amandla okuqondiwe njengesisekelo somklamo wethu. Ngaphansi kwesisekelo sokwanelisa ibhodi le-spectrum ne-EVM, lapho amandla okudlulisela ekhulu, kuba ngcono ukusebenza.
    2. Ukwamukela ukuzwela (I-RX Sensitivity): Ipharamitha ebonisa ukusebenza kokwamukela kwe-DUT. Lapho ukuzwela kokwamukela kube ngcono, amasiginali awusizo kakhulu ewatholayo, futhi kuyanda ukumbozwa kwayo okungenantambo. Lapho uhlola ukuzwela kokwamukela, yenza umkhiqizo ube sesimweni sokwamukela, sebenzisa idivayisi yokulinganisa ye-WiFi ukuthumela ifayela elithile le-waveform, futhi umkhiqizo uzolithola, futhi izinga lamandla elithunyelwe lingashintshwa kudivayisi yokulinganisa ye-WiFi kuze kube iphakethe lomkhiqizo. isilinganiso sephutha (PER%) sihlangabezana nezinga elijwayelekile .
    3. Iphutha Lefrikhwensi (Iphutha Lefrikhwensi): Imele ukuchezuka kwesignali ye-RF ukusuka kumafrikhwensi aphakathi nendawo lapho isignali ikhona, ku-PPM.
    4. I-Error Vector Magnitude (EVM): Kuyinkomba yokucabangela ikhwalithi yesiginali eshintshiwe, futhi iyunithi iyi-dB. I-EVM encane, ingcono ikhwalithi yesiginali. Emkhiqizweni ongenazintambo, amandla e-TX kanye ne-EVM ahlobene. Ubukhulu be-TX Power, i-EVM enkulu, okungukuthi, ikhwalithi yesignali iba yimbi kakhulu. Ngakho-ke, ekusebenzeni okusebenzayo, kufanele kwenziwe ukuvumelana phakathi kwe-TX Power ne-EVM.
    5. I-Transmit Spectrum Mask yesiginali edlulisiwe ingakala ikhwalithi yesiginali edlulisiwe kanye nekhono lokucindezela ukuphazamiseka eziteshini eziseduze. Imaski ye-spectrum yesiginali ngaphansi kokuhlolwa ifaneleka ngaphakathi kwemaski ye-spectrum evamile.
    6. Ishaneli ibizwa nangokuthi isiteshi (Ishaneli) noma ibhendi yefrikhwensi, okuyishaneli yokudlulisa isignali yedatha enesignali engenawaya (i-electromagnetic wave) njengesithwali sokudlulisela. Amanethiwekhi angenantambo (imizila, izindawo ze-AP, amakhadi angenawaya ekhompuyutha) angasebenza eziteshini eziningi. Amadivaysi enethiwekhi angenantambo ahlukahlukene endaweni ekhavayo yamasignali angenantambo kufanele azame ukusebenzisa amashaneli ahlukene ukugwema ukuphazamiseka phakathi kwamasignali.
