Kini dualband ONU

Dualband ONU ni a tun pe ni 5G onu, ati pe o tun le pe ni AC onu.

Nitorina kini dualband onnu?

Gẹgẹbi apewọn ti nẹtiwọọki alailowaya, dualband onu yoo dara ju ọkan-band onu.Yoo jẹ ọkan ti o gbajumọ julọ ni ọjọ iwaju.

IEEE 802.11ac

IEEE 802.11ac jẹ boṣewa ibaraẹnisọrọ nẹtiwọọki kọnputa alailowaya 802.11 to sese, eyiti o nlo band igbohunsafẹfẹ 6GHz (ti a tun mọ ni band igbohunsafẹfẹ 5GHz) fun ibaraẹnisọrọ agbegbe alailowaya (WLAN).Ni imọran, o le pese o kere ju 1 Gigabit fun bandiwidi keji fun awọn ibaraẹnisọrọ agbegbe agbegbe alailowaya (WLAN), tabi o kere ju 500 megabits fun iṣẹju kan (500 Mbit / s) fun bandiwidi gbigbe asopọ kan.

O gba ati faagun ero wiwo wiwo afẹfẹ ti o wa lati 802.11n, pẹlu: bandiwidi RF ti o gbooro (ti o to 160 MHz), awọn ṣiṣan aye MIMO diẹ sii (pọ si 8), MU-MIMO, Ati demodulation iwuwo giga (atunṣe, to 256QAM). ).O jẹ arọpo ti o pọju si IEEE 802.11n.
