Wow, huh?I miss the era I was saying.
Wi-Fi is indispensable for life.Wi-Fi 6 (802), which is faster, wider compatible bandwidth (802.11AX) is almost over.Like mobile communication, Wi-Fi is also evolving.But there will be such people."If 5G is widespread, Wi-Fi doesn't need it?"There are both 5G and Wi-Fi 6!The industry group Wi-Fi Alliance talks about 2019, where 5G and Wi-Fi 6 coexist.
Why does Wi-Fi go away even if 5G spreads?
Wi-Fi is flying around so much that it can be a comic story.That sense of security when Wi-Fi is connected at an overseas travel destination!Now, Wi-Fi is one of the most popular technical standards worldwide.Wi-Fi can be used quickly, where you can use your home, a nearby cafe, an overseas hotel, wherever you go.According to Wi-Fi Alliance, more than half of the world communication data are via Wi-Fi.87 % of smartphone data is also via Wi-Fi.Even if you upgrade to Wi-Fi 6, the old device leads to the Wi-Fi 6 router, and it is convenient that a new device compatible with Wi-Fi 6 leads to an old router.Of course, the maximum speed may not be demonstrated, but the kimo is that it is hard to connect.
In addition, Wi-Fi Alliance points out that individuals, companies, businesses, anyone can easily upgrade to Wi-Fi 6.Depending on where you live, Wi-Fi 6 may come before 5g.
The disadvantage of mobile data communication is ease of connection.Despite the spread of public Wi-Fi, mobile data communication is always on most places.
With the appearance of 5G, more terminals can be connected to the Internet in more places.Not only smartphones and personal computers.It is one of the terminals that can be connected to security cameras and autonomous cars.However, there is also a place where Wi-Fi is active here.
Wi-Fi Halow (802 (802.11Ah).Wifi Halow, which is excellent in bandwidth and power consumption in exchange for speed, is a perfect partner for smart home terminals that do not need to stream, but need to be connected regularly.Because it does not eat power, it goes well with wearable terminals and remote sensors around smart home.Wi-Fi Alliance pushes Wi-Fi Halow for 5G alternative communication depending on the situation.
It is an ultra-high speed of 5g, 10 gigabit per second, but Wi-Fi is as good as losing.Wigig (60GHz, 802.With the next-generation Wi-Fi technology called 11ay), you can keep up with 5G speed.However, since the band area is narrower than the standard Wi-Fi 6, wiring in the room used is required.However, once it is installed, the 4K video and the VR/AR game are all -you -can -eat.It is worth investing as a home theater or shop facilities.
Which is Wi-Fi 6 or 5g?The question is nonsense.It is not the question of which is better, but only coexisting.While mobile data is used more widely and more frequently, Wi-Fi will continue, mainly for indoor use.Mobile data and Wi-Fi will continue to coexist, as they have coexisted so far, whether 5G or Wi-Fi 6 appears.However, the biggest advantage of Wi-Fi Alliance pushing Wi-Fi is that the frequency used by Wi-Fi 6 does not require a license.Mobile data such as 5G requires conditions for use, regulation, license acquisition and operation.
