Dual
band wifi ONU means the ONU with the dual band wifi. What is the advantages
of dual band ONU?
1、what
is dual band wifi?
Dual-band
Wifi is 2.4 GHz and 5 GHz dual-band wireless signals which support 802.11a/b/g/n/ac
wireless network. Dual band wifi belongs to the fifth generation Wi-Fi
transmission technology (5G Wi-Fi).
The dual-band WiFi refers to the wireless signal that supports two different
bands at the same time. These two bands are 2.4 and 5 G respectively.
At present, most wireless products adopt single-frequency 2.4G WiFi
wireless transmission, such as wireless mouse, keyboard, USB wireless network
card, ordinary wireless router and so on. Only high-end smart devices support
dual-band WiFi technology, such as "some ONU,some mobile phones,
tablets, high-end wireless routers" and so on.
2、what
is the advantage of dual band wifi?
The 2.4G
band signal has relatively good penetration and relatively long coverage
distance. But there are too many devices with 2.4G. At present, in the family
environment, the average number of 2.4G APs (Wireless Access Point) that a
family can search around has exceeded 5. The environment of 2.4G is becoming
more and more noisy and disturbing.
Why is 5G WiFi more stable and
faster than 2.4G wifi? The 2.4G only provide three channels signal which do
not interfere with each other. 5G can provide 22 channels signals. In another
point, there is only few device with 5G wifi signal. So 5G channels are clean
and faster. In the case of transmitting the same amount of data, 5G will save
electricity and have a better user experience.
3、What
is the advantage of dual band ONU?
Dual
band wifi ONU can support both 2.4GHz and 5GHz frequency at same time. Dual
band wifi ONU has both advantages of 2.4G and 5G, which not only provide good
penetration and relatively long coverage distance 2.4G wifi signal but also
provide clean and much faster 5G wifi signal.
4、Can 2.4G/5G auto switched?
The 2.4G wifi and 5G wifi have their different SSID. They are different wifi, can not switch automatically.
