Antenna chinhu chinoshandiswa, icho chinonyanya kukanganisa simba reOTA, kunzwa, kuvharika kwehuwandu uye chinhambwe, nepo OTA iri nzira yakakosha yekuongorora nekugadzirisa dambudziko rekubuda. Kazhinji, isu tinonyanya kuyera antenna zvichienderana neanotevera paramita (kuita kuchakanganisawo kuita kwekuita):
a)VSWR:
Pima dhigirii rekuratidzwa kwechiratidzo chekuisa pane antenna feed point. Kukosha uku hakureve kuti kuita kweantenna kwakanaka, asi kukosha hakuna kunaka, zvinorevaanotevera ma paramita haatarise kukanganisa kwerabhoritari, iyo chaiyo antenna dhizaini kuti simba rekuisa kune antenna feed point kumagumo ePCBA rinoratidzwa zvakanyanya, uye simba rinogona kushandiswa kupenya rakaderedzwa kupfuura iro reiyo yakanaka kumira wave antenna.
b) Kugona basa:
Huyero hwesimba rinovhenekerwa neantenna kune simba rekuisa kune antenna feed point inozokanganisa zvakananga kuita kweWi-Fi OTA simba (TRP) uye kunzwa (TIS)
c) Kuwana:
Inomiririra chiyero chesimba pakati peimwe chinzvimbo munzvimbo yenzvimbo uye yakanakira poindi sosi antenna kana simba rekuisa rakafanana. Iyo passive data yeOTA kazhinji ndiyo yakanyanya kuwana kukosha kweiyo imwe frequency (chiteshi) pane sphere, iyo inonyanya kuenderana neyekufambisa kureba.
d) TRP/TIS:
Aya maratidziro maviri akakwana anowanikwa nekubatanidza uye nekuenzanisa iyo yese radiation sphere yenzvimbo yemahara (iyo inogona kunzwisiswa seOTA laboratory nharaunda), uye inogona kuratidza zvakananga kuita kweWi-Fi yechigadzirwa (OTA performance yePCBA hardware + mold. + antenna).
Muedzo weTRP/TIS wakasiyana zvakanyanya kubva pane zvinotarisirwa, zvinodikanwa kuti utarise kuti Wi-Fi inopinda mune yakaderera simba modhi, uye kune bhatiri zvigadzirwa zvine simba, zvakare zvinodiwa kutarisa kana simba rakakwana panguva yekuedzwa. ; Mukuwedzera, TRP inoda kubhadhara kune ACK uye kwete-ACK modes, uye TIS yakagara iri kutarisa uye kuoma muOTA, shure kwezvose, kufambisa kunogona kuratidza chikamu chekupindira kwemamiriro ezvinhu, kuwedzera, software zvinhu zvichavawo kukanganisa paTIS.
TRP/TIS inogona kushandiswa senzira yakakosha yeWi-Fi throughput analysis.
e) Dhiagiramu yenzira:
Inoshandiswa kunyatsoongorora huwandu hwekuvharidzirwa kwemwaranzi yechigadzirwa munzvimbo, data rayo rekuyedza rinowanzosiyaniswa zvichienderana ne frequency (chiteshi), imwe neimwe frequency ine H, E1, E2 zviso zvitatu, zvichiratidza kuvharika kwechiratidzo chechikamu chese che antenna. . Iyo Wi-Fi yechigadzirwa isina waya yekuvhara inosimbiswa nekuyedza iyo throughput pamakona akawanda kana ichinyatso shandiswa kureba (iyo dhizaini haigone kumiririrwa kana chinhambwe chave pedyo).
f) Dhigirii rekuzviparadzanisa nevamwe:
Iyo yekuzviparadzanisa dhigirii inoyera iyo yekuzviparadzanisa dhigirii yeWi-Fi akawanda-channel antennas uye kuwirirana kubatana pakati peantenna. Dhigirii rakanaka rekuzviparadzanisa nevamwe rinogona kuderedza kuwirirana pakati peantenna, uye ine dhiyabhorosi yakanaka, kuitira kuti muchina wese uve nevhavha isina waya isina waya..
Zviri pamusoro apaHDVPhoerekitironiTechnology Ltd yakaunza tsananguro yeruzivo ye "Wi-Fi antenna", uye michina yenetiweki yekambani yedu ndeiyi: OLT ONU/ AC ONU/ communication ONU/ optical fiber ONU/gpon ONU/EPON ONU zvichingodaro, tinokugamuchirai kuti munzwisise.
