Zvigadzirwa zveWiFi zvinoda kuti isu tiyere nemaoko uye kugadzirisa ruzivo rwemagetsi eWiFi yechigadzirwa chimwe nechimwe, saka yakawanda sei yaunoziva nezve maparamita eWiFi calibration, rega ndikuzivise:
1. Kutumira simba (TX Power): inoreva simba rekushanda rekutumira antenna yechigadzirwa chisina waya, chikwata chiri dBm. Simba rekutumira kusina wireless rinotarisa simba uye chinhambwe chechiratidzo chisina wire, simba guru, simba rechiratidzo. Mune isina waya chigadzirwa dhizaini, pachagara paine chinangwa chesimba sehwaro hwekugadzira kwedu. Pasi pemamiriro ekugutsa spectrum board uye EVM, iyo yakakura simba rekutumira, zvirinani kuita.
2. Kugamuchira senitivity (RX Sensitivity): Chiratidzo chinoratidza kushanda kwekugamuchira kweDUT. Iyo iri nani iyo yekugamuchira senitivity, iyo inonyanya kubatsira masaini yainogashira, uye yakakura iyo yayo isina waya yekuvhara. Paunenge uchiyedza kunzwisiswa kwekugamuchira, gadzira chigadzirwa munzvimbo yekugamuchira, shandisa iyo WiFi calibration mudziyo kutumira chaiyo waveform faira, uye chigadzirwa chinochigashira, uye iyo nhanho yemagetsi inotumirwa inogona kugadziridzwa paWiFi calibration mudziyo kusvika pakiti yechigadzirwa. mwero wekukanganisa (PER%) unoenderana neyakajairwa .
3. Frequency Error (Frequency Error): Inomiririra kutsauka kwechiratidzo cheRF kubva pakati pefrequency yechiteshi icho chiratidzo chiripo, muPPM.
4. Kukanganisa Vector Magnitude (EVM): Indekisi yekutarisa kunaka kweiyo modulated chiratidzo, uye iyo unit ndeye dB. Iyo diki iyo EVM, zviri nani iyo chiratidzo chemhando. Muchigadzirwa chisina waya, TX simba uye EVM zvine hukama. Iyo yakakura iyo TX Simba, iyo yakakura iyo EVM, ndiko kuti, yakaipisisa yemhando yechiratidzo. Naizvozvo, mukushandisa zvinoshanda, kuwirirana kunofanirwa kuitwa pakati peTX Power neEVM.
5. Iyo Transmit Spectrum Mask yechiratidzo chinotapuriranwa chinogona kuyera kunaka kwechiratidzo chinotapurirwa uye kugona kudzvinyirira kupindira kune ari pedyo nzira. Iyo spectrum mask yechiratidzo pasi pekuyedzwa inokodzera mukati meiyo yakajairwa spectrum mask.
6. Iyo chiteshi inonziwo chiteshi (Channel) kana frequency bhendi, inova data chiratidzo chekufambisa chine waya isina waya (electromagnetic wave) semutakuri wekutakura. Wireless network (routers, AP hotspots, komputa isina waya makadhi) inogona kushanda pamatanho akawanda. Zvishandiso zvakasiyana-siyana zvisina waya zvetiweki mukati menzvimbo yekuvhara masaini masaini anofanira kuedza kushandisa nzira dzakasiyana kudzivirira kukanganisa pakati pezviratidzo.
