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