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 (5GWi-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.
