Cov khoom lag luam WiFi xav tau peb los ntsuas tus kheej thiab ntsuas cov ntaub ntawv hluav taws xob WiFi ntawm txhua yam khoom, yog li koj paub ntau npaum li cas txog qhov tsis muaj WiFi calibration? Cia kuv qhia rau koj hauv qab no:
1, TX Fais fab: hais txog cov khoom siv wireless xa cov kav hlau txais xov ua haujlwm lub zog, chav tsev yog dBm. Lub zog ntawm kev xa xov wireless txiav txim siab lub zog thiab kev ncua deb ntawm wireless signals. Lub zog loj dua, lub teeb liab muaj zog dua. Hauv kev tsim cov khoom siv wireless, muaj lub hom phiaj lub zog raws li lub hauv paus ntawm peb cov qauv tsim, nyob rau hauv qhov chaw ntawm lub rooj sib tham ntawm cov phaj spectrum thiab EVM, qhov loj dua lub zog xa mus, qhov ua tau zoo dua.
2. RX Sensitivity: ib tug parameter uas characterizes lub txais tos kev ua tau zoo ntawm cov khoom yuav tsum tau kuaj. Qhov zoo dua qhov txais tos rhiab heev yog, qhov muaj txiaj ntsig zoo dua nws yuav tau txais thiab qhov loj dua nws cov kev pabcuam wireless. Thaum kuaj qhov tau txais rhiab heev, ua cov khoom nyob rau hauv lub xeev tau txais, siv lub WiFi calibration ntaus ntawv xa cov ntaub ntawv waveform tshwj xeeb, thiab cov khoom tau txais. Lub hwj chim theem ntawm kev xa tuaj yeem hloov kho ntawm WiFi calibration ntaus ntawv kom txog thaum lub pob ntawv yuam kev (PER%) ntawm cov khoom ua tau raws li tus qauv.
3. Zaus yuam kev: sawv cev rau qhov loj ntawm qhov sib txawv ntawm RF teeb liab los ntawm qhov nruab nrab zaus ntawm cov channel uas lub teeb liab nyob (unit PPM).
4, kev ua yuam kev vector amplitude (EVM): yog qhov taw qhia los txiav txim siab qhov zoo ntawm cov teeb liab modulation, chav tsev yog dB. Qhov me me ntawm EVM, qhov teeb meem zoo dua. Hauv cov khoom siv wireless, TX Power thiab EVM muaj feem cuam tshuam, qhov loj dua TX Power, qhov loj dua EVM, uas yog, qhov teeb meem tsis zoo, yog li hauv kev siv tswv yim, coj kev sib haum xeeb ntawm TX Power thiab EVM.
5. Tus qauv offset zaus ntawm cov teeb liab kis tau tuaj yeem ntsuas qhov zoo ntawm cov teeb liab kis tau tus mob thiab muaj peev xwm cuam tshuam kev cuam tshuam ntawm cov channel uas nyob ib sab. Lub spectrum template ntawm lub teeb liab ntsuas yog tsim nyog nyob rau hauv tus qauv spectrum template.
6. Channel, tseem hu ua channel thiab zaus band, yog cov ntaub ntawv teeb liab kis tau tus mob channel nrog wireless teeb liab (electromagnetic yoj) raws li cov khoom sib kis. Wireless networks (routers, AP hotspots, khoos phis tawj wireless phaib) tuaj yeem khiav ntau txoj hauv kev. Nyob rau hauv ntau yam ntawm wireless teeb liab kev pab them nqi ntawm ntau yam wireless network khoom siv yuav tsum sim siv cov sib txawv raws kom tsis txhob cuam tshuam ntawm cov teeb liab.
