    Intshayelelo emfutshane kwii-Antenna zeWi-Fi

    Ixesha lokuposa: Jun-14-2022

    I-Antenna sisixhobo sokwenziwa, ikakhulu sichaphazela amandla e-OTA kunye novakalelo, ukugubungela kunye nomgama, kwaye i-OTA yindlela ebalulekileyo yokuhlalutya kunye nokusombulula ingxaki yokuphuma, ngokuqhelekileyo thina ikakhulu kwiiparameters ezilandelayo (ezi parameters zilandelayo aziyicingi impazamo yebhubhoratri; olona yilo loyilo lwe-eriyali luza kuchaphazela ukusebenza kwe-output):

    a) VSWR

    Ukulinganisa iqondo lokubonisa imiqondiso yegalelo kwindawo yesondlo se-eriyali. Eli xabiso alithethi ukuba ukusebenza kwe-eriyali kulungile, kodwa ixabiso alilungile, lithetha ukuba igalelo lamandla kwindawo yokutya ye-eriyali libonakaliswa ngakumbi, xa kuthelekiswa ne-eriyali yokuma kwamaza elungileyo, amandla anokusetyenziswa kwimitha yelanga. iye yancitshiswa ngakumbi.

    b) ukuvelisa

    Umlinganiselo wamandla asasazwa yi-eriyali ukuya kwigalelo lamandla kwindawo yokutya ye-antenna iya kuchaphazela ngokuthe ngqo amandla e-Wi-Fi OTA (TRP) kunye novakalelo (TIS) ukusebenza.

    c) inzuzo

    Imele umlinganiselo wamandla wendawo kumkhombandlela wendawo ukuya kwindawo eyiyo yomthombo we-eriyali apha, ngelixa idatha yokwenziwa kwe-OTA idla ngokuba yinzuzo ephezulu yefrikhwensi enye (itshaneli) kwisphere, ikakhulu enxulumene nomgama wothumelo.

    d) TRP/TIS

    Ezi zalathisi zibini ezibanzi zifunyenwe ngokudibanisa yonke i-radiation sphere yendawo ekhululekile (enokuthi iqondwe njengemeko ye-laboratory ye-OTA), enokuthi ibonise ngokucacileyo ukusebenza kwe-Wi-Fi yemveliso (i-PCBA hardware + i-OTA yokusebenza kwe-mold + antenna).

    Xa uvavanyo lwe-TRP / TIS luhluke kwizinto ezilindelekileyo, nikela ingqalelo ukuba i-Wi-Fi ingena kwimodi yamandla aphantsi kunye neemveliso zebhetri; I-TRP kufuneka igxininise kwimodi ye-ACK kunye ne-non-ACK, kwaye i-TIS ibisoloko iphambili kwi-OTA, emva koko, ukuhanjiswa kunokubonakalisa kuphela ukuphazamiseka okuthile, izinto zesoftware ziya kuchaphazela ne-TIS.

    I-TRP / TIS ingasetyenziswa njengendlela ebalulekileyo yohlalutyo lwe-Wi-Fi throughput.

    e) umzobo wesalathiso

    Isetyenziselwa ukuvavanya ngokomgangatho ukugutyungelwa kwemitha yemveliso esithubeni, kwaye idatha yovavanyo idla ngokwahlulwa ngokwezihlandlo (itshaneli), ifreyithingi nganye inobuso obuthathu: H, E1 kunye ne-E2, ukuze kuphawulwe ukugubungela umqondiso. yonke ingqukuva ye-eriyali. Xa imveliso ye-Wi-Fi isetyenziswe ngokwenene kumgama omde (xa itshathi yokuqhelaniswa nayo ingenakubonakaliswa kumgama osondeleyo), i-wireless signal coverage yemveliso ngokwenene iqinisekiswa ngokuvavanya i-throughput kwii-angles ezininzi.

    f) ukugquma

    Isidanga sokwahlukaniswa silinganisa iqondo lokuzikhethela le-eriyali enezitishi ezininzi ze-Wi-Fi kunye nokudibanisa phakathi kwee-eriyali. Idigri elungileyo yokwahlula inokunciphisa ukudityaniswa kwe-eriyali kwaye ibe nemephu yesalathiso elungileyo, ukuze umatshini wonke ube nophawu olululo olululo olungenazingcingo.
