Dualband ONU tseem hu ua 5G onu, thiab nws tseem tuaj yeem hu ua AC onu.
Yog li dab tsi yog lub dualband onu?
Raws li tus qauv ntawm wireless network, dualband onu yuav zoo dua ib leeg-band onu.Nws yuav yog qhov nrov tshaj plaws nyob rau yav tom ntej.
IEEE 802.11 ua
IEEE 802.11ac yog tus tsim 802.11 wireless computer network kev sib txuas lus tus qauv, uas siv 6GHz zaus band (tseem hu ua 5GHz zaus band) rau wireless hauv cheeb tsam network (WLAN) kev sib txuas lus.Hauv txoj kev xav, nws tuaj yeem muab tsawg kawg 1 Gigabit ib thib ob bandwidth rau ntau lub chaw nres tsheb wireless hauv cheeb tsam network (WLAN) kev sib txuas lus, lossis tsawg kawg 500 megabits ib ob (500 Mbit / s) rau ib qho kev sib txuas sib txuas ntawm ib qho bandwidth.
Nws txais thiab nthuav dav cov huab cua interface tswv yim muab los ntawm 802.11n, suav nrog: dav RF bandwidth (txog 160 MHz), ntau MIMO spatial kwj (nce mus rau 8), MU-MIMO, Thiab high-density demodulation (modulation, mus txog 256QAM ).Nws yog qhov muaj peev xwm ua tau zoo rau IEEE 802.11n.
Peb lub tuam txhab, Shenzhen HUANET Technology CO., Ltd muaj peev xwm muab tau txhua yam ntawm dualband onts.Nov yog qee qhov piv txwv ntawm ob hom onu.
Lub 5GHz WiFi siv lub zaus ntau dua los ua kom muaj kev sib tsoo tsawg dua.Nws siv 22 channel thiab tsis cuam tshuam rau ib leeg.Piv nrog rau 3 raws ntawm 2.4GHz, nws txo cov teeb liab congestion.Yog li, tus nqi sib kis ntawm 5GHz yog 5GHz sai dua 2.4GHz.
5GHz Wi-Fi zaus band siv lub thib tsib tiam 802.11ac raws tu qauv tuaj yeem ncav cuag kev sib kis ceev ntawm 433Mbps hauv qab bandwidth ntawm 80MHz, thiab kev sib kis ceev ntawm 866Mbps nyob rau hauv bandwidth ntawm 160MHz, piv rau 2.4GHz kis tau tus nqi siab tshaj. tus nqi ntawm 300Mbps Tau txais kev txhim kho zoo heev.
Txawm li cas los xij, 5GHz Wi-Fi kuj muaj qhov tsis txaus.Nws shortcomings nyob rau hauv lub kis tau tus mob nyob deb thiab muaj peev xwm mus hla obstacles.
Vim Wi-Fi yog ib qho hluav taws xob nthwv dej, nws txoj kev nthuav tawm tseem ceeb yog txoj kab ncaj nraim.Thaum nws ntsib obstacles, nws yuav tsim kev nkag mus, xav txog, diffraction thiab lwm yam tshwm sim.Ntawm lawv, kev nkag mus yog qhov tseem ceeb, thiab ib feem me me ntawm cov teeb liab yuav tshwm sim.Reflection thiab diffraction.Cov yam ntxwv ntawm lub cev ntawm cov xov tooj cua tsis yog qhov qis dua, qhov ntev ntawm lub wavelength, qhov me dua qhov poob thaum lub sij hawm nthuav tawm, qhov dav ntawm qhov kev pab cuam, thiab qhov yooj yim dua nws yog hla obstacles;qhov ntau zaus, qhov me me ntawm qhov kev pab them nqi thiab qhov nyuaj dua.Mus ncig obstacles.
Yog li ntawd, 5G teeb liab nrog lub siab zaus thiab luv luv wavelength muaj qhov kev pab cuam me me, thiab lub peev xwm dhau los ntawm cov teeb meem tsis zoo li 2.4GHz.
Hais txog kev sib kis, 2.4GHz Wi-Fi tuaj yeem ncav cuag qhov siab tshaj plaws ntawm 70 meters hauv tsev, thiab qhov siab tshaj plaws ntawm 250 meters sab nraum zoov.Thiab 5GHz Wi-Fi tsuas tuaj yeem ncav cuag qhov siab tshaj plaws ntawm 35 meters hauv tsev.
