Dualband ONU inonziwo 5G onu, uye inogonawo kunzi AC onu.
Saka chii chinonzi dualband onu?
Zvichienderana netsika yenetwork isina waya, dualband onu ichave iri nani pane single-band onu. Ichava onu inonyanya kufarirwa mune ramangwana.
IEEE 802.11ac
IEEE 802.11ac imhando yekutaurirana kwemakombiyuta isina waya ye802.11, iyo inoshandisa bhendi re6GHz (rinozivikanwawo sebhendi re5GHz frequency) rekutaurirana kwenetwork yenzvimbo isina waya (WLAN). Mukufunga, inogona kupa bandwidth yeGigabit imwe pasekondi yekutaurirana kwenetwork yenzvimbo isina waya (WLAN) ine chiteshi chemagetsi, kana kuti 500 megabits pasekondi (500 Mbit/s) yebandwidth imwe chete yekutumira data.
Inoshandisa uye inowedzera pfungwa ye air interface inobva ku802.11n, kusanganisira: bandwidth yakafara yeRF (kusvika ku160 MHz), maMIMO spatial streams akawanda (akawedzera kusvika ku8), MU-MIMO, Uye high-density demodulation (modulation, kusvika ku256QAM). Inogona kutsiva IEEE 802.11n.
Kambani yedu, Shenzhen HUANET Technology CO., Ltd, inogona kupa marudzi ese emhando dze dualband onts. Heano mamwe mamodheru e dualband onu.
5GHz WiFi inoshandisa bhendi rema frequency akawanda kuti iite kuti pave nekuzara kwema channels mashoma. Inoshandisa ma channels makumi maviri nemaviri uye haipindirani. Kana ichienzaniswa nema channels matatu e2.4GHz, inoderedza zvakanyanya kuzara kwema signal. Saka huwandu hwekutumira ma signal e5GHz hunokurumidza kupfuura 2.4GHz.
Bhandi reWi-Fi re5GHz rinoshandisa protocol yechizvarwa chechishanu ye802.11ac rinogona kusvika pakumhanya kwekutumira kwe433Mbps pasi pebandwidth ye80MHz, uye kumhanya kwekutumira kwe866Mbps pasi pebandwidth ye160MHz, zvichienzaniswa ne2.4GHz transmission rate yepamusoro ye300Mbps. Yakagadziridzwa zvakanyanya.
Zvisinei, Wi-Fi ye5GHz inewo zvikanganiso. Zvikanganiso zvayo zviri mudaro rekutumira magiya uye kugona kwayo kuyambuka zvipingamupinyi.
Nekuti Wi-Fi iwaya remagetsi, nzira yayo huru yekupararira ndeyekuparadzira mutsetse wakatwasuka. Kana ikasangana nezvipingamupinyi, inoburitsa kupinda, kuratidzira, kupararira nezvimwe zviitiko. Pakati pazvo, kupinda ndiko kukuru, uye chikamu chidiki chechiratidzo chichaitika. Kufungisisa nekupararira. Hunhu hwemafungu eredhiyo ndehwekuti kana frequency yakaderera, kureba kwewavelength, kurasikirwa kudiki panguva yekupararira, kufukidzwa kwakafara, uye zviri nyore kudarika zvipingamupinyi; frequency yakakwira, kufukidzwa kudiki uye kuoma kwakanyanya. Enda uchitenderedza zvipingamupinyi.
Saka, chiratidzo che5G chine mafrequency akawanda uye marefu mapfupi chine nzvimbo diki yekuvhara, uye kugona kupfuura nezvipingamupinyi hakuna kunaka se2.4GHz.
Panyaya yekureba kwekutumira mameseji, 2.4GHz Wi-Fi inogona kusvika pamamita makumi manomwe mukati meimba, uye 250 metres kunze. Uye 5GHz Wi-Fi inogona kusvika pamamita makumi matatu nemashanu mukati meimba.
Nguva yekutumira: Chikunguru-03-2023
