Zvigadzirwa zveWiFi zvinoda kuti isu tiyere nemaoko uye kugadzirisa ruzivo rwemagetsi eWiFi yechigadzirwa chega chega, saka yakawanda sei yaunoziva nezve maparamita eWiFi calibration?Rega ndikuzivise pazasi:
1, TX Simba: inoreva iyo isina waya chigadzirwa chinotumira antenna kushanda simba, iyo unit iri dBm.Simba rekutumira isina waya rinotarisa kusimba uye kureba kwemasaini asina waya.Iyo yakakura simba, iyo yakasimba chiratidzo.Mune isina waya yechigadzirwa dhizaini, kune simba rakanangwa sehwaro hwedhizaini yedu, muchimiro chekusangana nedhizaini ndiro uye EVM, iyo yakakura simba rekutapurirana, zvirinani kuita.
2. RX Sensitivity: parameter inoratidza kushanda kwekugamuchira kwechinhu chinofanira kuongororwa.Izvo zvirinani kunzwisiswa kwekugamuchira kuri, iyo inonyanya kubatsira masaini iyo ichagamuchira uye yakakura yayo isina waya yekuvhara.Paunenge uchiyedza kunzwa kwekugamuchira, gadzira chigadzirwa munzvimbo yekugamuchira, shandisa iyo WiFi calibration mudziyo kutumira chaiwo waveform mafaera, uye chigadzirwa chinogashira.Iyo yemagetsi nhanho yekutumira inogona kugadziridzwa pane yeWiFi calibration mudziyo kusvika iyo packet kukanganisa mwero (PER%) yechigadzirwa yasangana neyakajairwa.
3. Kakawanda Kanganiso: inomiririra ukuru hwekutsauka kwechiratidzo cheRF kubva pakati peiyo frequency yechiteshi icho chiratidzo chinowanikwa (unit PPM).
4, kukanganisa vector amplitude (EVM) : chiratidzo chekutarisa kunaka kweiyo modulation chiratidzo, iyo unit ndeye dB.Iyo diki iyo EVM, zviri nani iyo chiratidzo chemhando.Muchigadzirwa chisina waya, TX Power neEVM zvine hukama, iyo yakakura iyo TX Power, iyo yakakura iyo EVM, ndiko kuti, yakaipisisa yemhando yechiratidzo, saka mumashandisirwo anoshanda, kutora chibvumirano pakati peTX Power neEVM.
5. The frequency offset template yechiratidzo chinotapuriranwa chinogona kuyera kunaka kwechiratidzo chinotapurirwa uye kupindira kwekudzvinyirira kugona kwechiteshi chiri pedyo.Iyo spectrum template yechiratidzo yakayerwa inokodzera mukati meiyo yakajairwa spectrum template.
6. Chiteshi, chinonziwo chiteshi uye frequency bhendi, idhizaini yedhata yekufambisa ine isina waya chiratidzo (electromagnetic wave) semutakuri wekutakura.Wireless network (marouter, AP hotspots, komputa isina waya makadhi) anogona kumhanya pamusoro akawanda chiteshi.Mukati meiyo isina waya yekuvhara masaini yeakasiyana mawaya network michina inofanirwa kuyedza kushandisa nzira dzakasiyana kudzivirira kukanganisa pakati pezvikwangwani.
