I-Antenna iyisisetshenziswa esingenzi lutho, esithinta kakhulu amandla e-OTA, ukuzwela, ububanzi bokuhlanganisa nebanga, kuyilapho i-OTA iyindlela ebalulekile yokuhlaziya nokuxazulula inkinga yokuphuma. Imvamisa, sikala i-antenna ngokuya ngamapharamitha alandelayo (ukusebenza kuzophinde kuthinte ukusebenza kokuphumayo) :
a)I-VSWR:
Linganisa izinga lokuboniswa kwesignali yokokufaka endaweni yokuphakelayo kwezithi. Leli nani alisho ukuthi ukusebenza kwe-antenna kuhle, kodwa inani alilihle, okusho ukuthiamapharamitha alandelayo awabheki iphutha laselabhorethri, idizayini ye-antenna yangempela ukuthi okokufaka kwamandla endaweni yokuphakela i-antenna ekugcineni kwe-PCBA kubonakala kakhulu, futhi amandla angasetshenziswa ukukhanyisa ancishiswe ngaphezu kwalawo we-antenna yokuma okuhle kwegagasi.
b) Ukusebenza kahle:
Isilinganiso samandla asakazwa uthi kuya kokokufaka kwamandla endaweni yokuphakelayo kwe-antenna kuzothinta ngokuqondile ukusebenza kwamandla e-Wi-Fi OTA (TRP) nokuzwela (TIS)
c) Ukuzuza:
Imele isilinganiso samandla phakathi kwesikhundla esithile endaweni kanye ne-antenna yomthombo wephoyinti efanelekile lapho amandla okufaka efanayo. Idatha ye-passive ye-OTA ngokuvamile iyinani eliphezulu lokuzuza lefrikhwensi eyodwa (isiteshi) esiyindilinga, ehlobene kakhulu nebanga lokudlulisela.
d) TRP/TIS:
Lezi zinkomba ezimbili ezibanzi zitholwa ngokuhlanganisa kanye nokulinganisa yonke inkundla yemisebe yendawo ekhululekile (engaqondwa njengendawo yaselabhorethri ye-OTA), futhi ingabonisa ngokuqondile ukusebenza kwe-Wi-Fi komkhiqizo (ukusebenza kwe-OTA kwe-PCBA hardware + isikhunta. + i-antenna).
Ukuhlolwa kwe-TRP/TIS kuhluke kakhulu kulokho okulindelekile, kuyadingeka ukunaka ukuthi i-Wi-Fi ingena kumodi yamandla aphansi, futhi emikhiqizweni yebhethri, kuyadingeka futhi ukuhlola ukuthi amandla anele yini ngesikhathi sokuhlolwa. ; Ukwengeza, i-TRP idinga ukunaka izindlela ze-ACK kanye ne-non-ACK, futhi i-TIS ibilokhu igxile kanye nobunzima ku-OTA, ngemva kwakho konke, ukuqhuba kungabonisa kuphela ingxenye yesimo sokuphazanyiswa, ngaphezu kwalokho, izici zesofthiwe nazo zizoba ne- umthelela ku-TIS.
I-TRP/TIS ingasetshenziswa njengendlela ebalulekile yokuhlaziywa kwe-Wi-Fi throughput.
e) Umdwebo wesikhombisi-ndlela:
Isetshenziselwa ukuhlola ngokwekhwalithi ububanzi bokumbozwa kwemisebe yomkhiqizo esikhaleni, idatha yawo yokuhlola imvamisa ukwehlukaniswa ngokuya ngefrikhwensi (isiteshi), imvamisa ngayinye inobuso obuthathu H, E1, E2, ngaleyo ndlela ikhombisa ukumbozwa kwesiginali yayo yonke i-antenna. . Ukufakwa kwesiginali engenantambo yomkhiqizo we-Wi-Fi empeleni kuqinisekiswa ngokuhlola ukuphuma kuma-engeli amaningi uma empeleni kusetshenziswe ebangeni elide (umdwebo wesikhombisi-ndlela awukwazi ukumelwa uma ibanga liseduze).
f) Iziqu zokuzihlukanisa:
Idigri yokuhlukanisa ikala idigri yokuhlukaniswa yama-antenna eziteshi eziningi ze-Wi-Fi kanye nokuhlangana phakathi kwezimpondo. Idigri enhle yokuhlukanisa inganciphisa ukuhlangana phakathi kwezimpondo, futhi ibe nomdwebo omuhle wesiqondiso, ukuze wonke umshini ube nesignali engcono engenantambo..
Okungenhla kunjaloI-HDVPhoi-electronI-Technology Ltd. ilethe incazelo yolwazi “ye-antenna ye-Wi-Fi,” kanye nemishini yenethiwekhi ehlobene yenkampani yethu yilena: OLT ONU/ AC ONU/ ukuxhumana ONU/ i-fiber optical ONU/gpon ONU/EPON ONU nokunye, siyakwamukela ukuze siqonde.
