Dualband ONU kuma ana kiransa 5G onu, kuma ana iya kiran shi AC onu.
To menene dualband onnu?
Bisa ga ma'auni na hanyar sadarwa mara waya, dualband onnu zai fi kyau fiye da onnu-band daya.Zai zama onu mafi shahara a nan gaba.
IEEE 802.11ac
IEEE 802.11ac shine ma'aunin sadarwar kwamfuta mara waya ta 802.11 mai tasowa, wanda ke amfani da rukunin mitar 6GHz (wanda kuma aka sani da rukunin mitar 5GHz) don sadarwar gida mara waya (WLAN).A ka'idar, yana iya samar da aƙalla 1 Gigabit a kowane sakan na bandwidth don sadarwar cibiyar sadarwa mara igiyar waya ta tashoshi masu yawa (WLAN), ko aƙalla megabits 500 a sakan daya (500 Mbit/s) don watsa bandwidth guda ɗaya.
