3.2 DFS txawv me ntsis
Cov khoom siv sib txuas lus wireless yuav tsum tau txais kev xaiv Dynamic Frequency Selection (DFS) cuam tshuam kev siv tshuab, uas yuav tsum tau hloov mus rau thiab tsis tuaj yeem teeb tsa nrog kev xaiv los tua DFS.
Qhov sib ntxiv ntawm cov khoom siv sib txuas lus wireless yuav tsum tau txais Kev Tswj Hluav Taws Xob (TPC) cuam tshuam kev cuam tshuam cov cuab yeej, nrog rau TPC ntau yam tsis pub tsawg tshaj 6dB; Yog tias tsis muaj TPC muaj nuj nqi, qhov sib npaug omnidirectional hluav taws xob hluav taws xob thiab qhov sib npaug omnidirectional hluav taws xob hluav taws xob spectral ceev txwv yuav tsum raug txo los ntawm 3dB.
3.3 Ua kom muaj kev tiv thaiv kev cuam tshuam ntxiv
Txoj kev txiav txim siab kev cuam tshuam kev cuam tshuam yog qhov pib ua raws li qhov yuav tsum tau ua ntawm CE daim ntawv pov thawj.
3.3.1 2.4G cuam tshuam kev zam:
①Thaum pom tias qhov zaus tau nyob, kev sib kis yuav tsum tsis txhob txuas ntxiv ntawm qhov zaus channel, thiab lub sijhawm nyob yuav tsum tsis pub tshaj 13ms. Uas yog hais tias, kev sib kis yuav tsum tau nres nyob rau hauv lub sij hawm nyob rau hauv ib tug channel.
② Cov cuab yeej muaj peev xwm tswj tau luv luv tswj cov teeb liab kis tau tus mob, tab sis lub luag hauj lwm lub voj voog ntawm lub teeb liab yuav tsum tsawg dua los yog sib npaug li 10%.
3.3.2 5G cuam tshuam kev zam:
①Thaum pom tias muaj lub teeb liab nrog kev siv zaus siab dua qhov kev kuaj pom, qhov kev sib kis yuav tsum tau nres tam sim ntawd, thiab lub sijhawm ua haujlwm siab tshaj plaws yog 20ms.
② Tsis pub dhau 50ms lub sijhawm soj ntsuam, tus naj npawb ntawm kev tswj cov teeb liab luv luv yuav tsum tsawg dua lossis sib npaug li 50 zaug, thiab thaum lub sijhawm soj ntsuam saum toj no, tag nrho lub sijhawm rau kev tswj cov teeb liab luv luv ntawm cov khoom siv yuav tsum tsawg dua 2500us lossis cov Lub luag hauj lwm lub voj voog ntawm qhov chaw luv luv ntawm cov teeb liab kis tau tus mob yuav tsum tsis pub tshaj 10%.
3.3.3 5.8G Interference Avoidance Requirements:
Ob qho tib si los ntawm cov kev cai qub thiab CE, tsis tas yuav tsum muaj 5.8G cuam tshuam kev zam, yog li 5.8G cuam tshuam kev zam ua rau muaj kev pheej hmoo ntau dua piv rau 5.1G thiab 2.4G wifi.
3.3.4 Bluetooth (BT) cuam tshuam kev zam:
SRRC tshiab yuav tsum muaj kev sim cuam tshuam kev zam rau Bluetooth, thiab tsis muaj kev zam rau (CE daim ntawv pov thawj tsuas yog xav tau rau lub zog ntau dua 10dBm).
Cov saum toj no yog tag nrho cov ntsiab lus ntawm cov kev cai tshiab. Peb cia siab tias txhua tus tuaj yeem ua tib zoo saib xyuas cov ntawv pov thawj siv sijhawm ntawm lawv tus kheej cov khoom thiab qhov sib txawv ntawm cov khoom tshiab kuaj raws sijhawm. Yog tias koj muaj lwm yam lus nug txog cov cai tshiab, thov koj tuaj yeem sab laj txhua lub sijhawm!
