I-Antenna iyisisetshenziswa esingenzi lutho, sithinta kakhulu amandla e-OTA nokuzwela, ukumbozwa kanye nebanga, futhi i-OTA iyindlela ebalulekile yokuhlaziya nokuxazulula inkinga yokuphuma, ngokuvamile thina ikakhulukazi ngamapharamitha alandelayo (amapharamitha alandelayo awalicabangeli iphutha elabhorethri, ukusebenza kwedizayini ye-antenna kuzophinde kuthinte ukusebenza kokuphumayo):
a) VSWR
Linganisa idigri yokuboniswa kwamasiginali okokufaka endaweni yokuphakela kwe-antenna. Leli nani alisho ukuthi ukusebenza kwe-antenna kuhle, kodwa inani alilihle, kusho ukuthi okokufaka kwamandla endaweni okuphakelayo kwe-antenna kubonakala kakhulu, uma kuqhathaniswa ne-antenna yamagagasi emile, amandla angasetshenziselwa imisebe. yehliswe kakhulu.
b) ukukhiqiza
Isilinganiso samandla akhishwa uthi kuya kokokufaka kwamandla endaweni yokuphakelayo yothi sizothinta ngokuqondile ukusebenza kwamandla e-Wi-Fi OTA (TRP) kanye nokuzwela (TIS).
c) inzuzo
Imele isilinganiso samandla sendawo endaweni eya ku-antenna yomthombo wephoyinti efanelekile lapha, kuyilapho idatha ye-OTA ngokuvamile iyinzuzo enkulu yefrikhwensi eyodwa (isiteshi) endimeni, ehlobene kakhulu nebanga lokudlulisela.
d) TRP/TIS
Lezi zinkomba ezimbili ezibanzi zitholwa ngokuhlanganisa yonke inkundla yemisebe yesikhala esikhululekile (engaqondwa njengendawo yelabhorethri ye-OTA), engabonisa ngokunembile ukusebenza kwe-Wi-Fi komkhiqizo (i-PCBA hardware + OTA ukusebenza kwesikhunta + i-antenna).
Uma ukuhlolwa kwe-TRP / TIS kuhlukile kulokho okulindelekile, qaphela ukuthi i-Wi-Fi ingena kumodi yamandla aphansi kanye nemikhiqizo esebenza ngebhethri; I-TRP idinga ukugxila kumodi ye-ACK kanye ne-non-ACK, futhi i-TIS ibilokhu iyiphuzu eliyinhloko ku-OTA, ngemva kwakho konke, ukudluliswa kungabonisa kuphela ukuphazamiseka okuthile, izici zesofthiwe zizophinde zithinte i-TIS.
I-TRP / TIS ingasetshenziswa njengendlela ebalulekile yokuhlaziywa kokuphuma kwe-Wi-Fi.
e) umdwebo oqondisayo
Isetshenziselwa ukuhlola ngokufanelekile ukumbozwa kwemisebe yomkhiqizo emkhathini, futhi idatha yokuhlola ivamise ukwehlukaniswa ngokuya ngefrikhwensi (isiteshi), imvamisa ngayinye inobuso obuthathu: H, E1 kanye no-E2, ukuze ibonise ukumbozwa kwesiginali yonke inkundla ye-antenna. Uma umkhiqizo we-Wi-Fi empeleni usetshenziswa ebangeni elide (lapho ishadi lomumo lingakwazi ukubonakala ebangeni eliseduze), ukumbozwa kwesignali engenantambo yomkhiqizo empeleni kuqinisekiswa ngokuhlola ukuphuma kuma-engeli amaningi.
f) ukwahlukanisa
Idigri ye-Isolation ikala izinga lokuhlukaniswa le-antenna yeziteshi eziningi ze-Wi-Fi kanye nokuhlangana okuhlangene phakathi kwezimpondo. Idigri enhle yokuhlukanisa inganciphisa ukuhlangana phakathi kwezimpondo futhi ibe nemephu yokuqondisa okuhle, ukuze wonke umshini ube nesiginali engenantambo.
