Dualband ONU inonzi zvakare 5G onu, uye inogona zvakare kunzi AC onu.
Saka chii chinonzi dualband onu?
Zvinoenderana neyakajairwa isina waya network, dualband onu ichave nani pane single-band onu.Ichava iyo inonyanya kufarirwa onu mune ramangwana.
IEEE 802.11ac
IEEE 802.11ac inosimudzira 802.11 isina waya komputa network network yekutaurirana standard, inoshandisa iyo 6GHz frequency bhendi (inozivikanwawo se5GHz frequency band) yewireless local area network (WLAN) kutaurirana.Muchiono, inogona kupa kanenge 1 Gigabit pasekondi bandwidth yemulti-station wireless local area network (WLAN) kutaurirana, kana angangoita 500 megabits pasekondi (500 Mbit/s) kune imwechete yekubatanidza transmission bandwidth.
Iyo inotora uye inowedzera iyo mhepo interface pfungwa inotorwa kubva ku802.11n, inosanganisira: yakafara RF bandwidth (kusvika 160 MHz), yakawanda MIMO spatial hova (yakawedzera kusvika 8), MU-MIMO , Uye yakakwirira-density demodulation (modulation, kusvika ku256QAM )Iyo inogona kutsiva IEEE 802.11n.
Kambani yedu, Shenzhen HUANET Technology CO., Ltd inogona kupa marudzi ese e dualband onts.Heano mamwe ma dualband onu modhi.
Iyo 5GHz WiFi inoshandisa yakakwira frequency bhendi kuunza kushoma chiteshi.Inoshandisa 22 chiteshi uye haikanganisi mumwe nemumwe.Kuenzaniswa nematanho matatu e2.4GHz, inoderedza zvakanyanya kuungana kwechiratidzo.Saka mwero wekutumira we5GHz ndeye 5GHz nekukurumidza kupfuura 2.4GHz.
Iyo 5GHz Wi-Fi frequency bhendi inoshandisa chizvarwa chechishanu 802.11ac protocol inogona kusvika pakumhanya kwe433Mbps pasi pe bandwidth ye80MHz, uye yekumhanyisa kumhanya kwe866Mbps pasi pe bandwidth ye160MHz, zvichienzaniswa neiyo 2.4GHz yekutapurirana mwero wepamusoro-soro. chiyero che300Mbps Yakagadziridzwa zvakanyanya.
Nekudaro, 5GHz Wi-Fi zvakare ine zvikanganiso.Kukanganisa kwayo kuri munhambwe yekufambisa uye kugona kuyambuka zvipingamupinyi.
Nekuti Wi-Fi ndeye electromagnetic wave, nzira yayo huru yekuparadzira ndiyo yakatwasuka mutsara kuparadzira.Kana ikasangana nezvipingamupinyi, inoburitsa kupinda, kuratidzira, diffraction uye zvimwe zviitiko.Pakati pavo, kupinda mukati ndiyo huru, uye chikamu chiduku chechiratidzo chichaitika.Reflection uye diffraction.Hunhu hwemuviri hwemasaisai eredhiyo ndehwekuti kuderera kwefrequency, kureba kwewavelength, kudiki kurasikirwa panguva yekuparadzira, kupararira kwekuvhara, uye zviri nyore kupfuura zvipingamupinyi;iyo yakakwirira frequency, iyo idiki yekuvhara uye yakanyanya kuoma.Enda kumativi zvipingamupinyi.
Naizvozvo, iyo 5G siginecha ine yakakwira frequency uye pfupi wavelength ine diki nzvimbo yekuvhara, uye kugona kupfuura nemuzvipingamupinyi hakuna kunaka se2.4GHz.
Panyaya yekufambisa kureba, 2.4GHz Wi-Fi inogona kusvika pakuvhara kwepamusoro kwemamita makumi manomwe mukati, uye kuvhara kwepamusoro kwemamita mazana maviri nemakumi mashanu kunze.Uye 5GHz Wi-Fi inogona chete kusvika pakuvhara kwepamusoro kwemamita makumi matatu neshanu mukati.
