O WiFi-6 It's getting there, but do you know what it means? The next generation of Wi-Fi promises to take our experiences to the next level. And don't just think that it is limited to an increment in speed. It's much more than that. Its advantages will be felt drop by drop in the long and medium term. Find out what awaits us: 172316
What is Wi-Fi 6? 393x2e
O Wi-Fi 6 is the next generation of Wi-Fi. We are currently in the fifth generation. It will still do the same basic thing – connect you to the internet – just with a bunch of additional technologies to make it happen more efficiently, speeding up connections in the process.
How fast can he be? m3m57
Short but incomplete answer: 9,6 Gbps. It's a lot, actually. That's because they are 3,5 Gbps No. Wi-Fi 5, the generation you have on your smartphone today. But the real answer isn't as sweet as it could be: these two speeds are stipulated maximum values, which you would likely never achieve in actual Wi-Fi usage.
And even if you could achieve those speeds, it's not clear that you're actually going to need them. To be more objective: the typical speed in the US, for example, is only 72 Mbps - or less than 1% of speed.
But the fact that the Wi-Fi 6 having a much higher speed limit than its predecessor is still important. That's because this 9,6 Gbps doesn't need to be directed at a single device. It's even better, it can be split across an entire network. That means more potential speed for each of your devices.
more than speed 1e1y
Instead of increasing the speed of individual devices, the Wi-Fi 6 it's all about improving the network when multiple devices are connected. This is an important objective, and it comes at an important moment: when the Wi-Fi 5 was released, a middle-class US family had about five devices Wi-Fi.
Homes now have nine devices Wi-Fi on average, and several companies predict that we will hit up to 50 within a few years. The Internet of Things (IoT) is real and it is creeping into our daily lives.
This means nothing more and nothing less that all these devices connected simultaneously can and will harm the quality and efficiency of your network. Demand that your current router probably wouldn't handle.
The mission of the Wi-Fi 6 introduces some new technologies to help mitigate the problems arising from placing dozens of devices Wi-Fi on a single network.
It allows routers to communicate with more devices at once, send data to multiple devices in the same transmission, and let the devices Wi-Fi program the calls check ins with the router. Together, these features should keep connections strong, even as more devices start demanding data.
Right, but what about each device? 286n1a
At first the connections Wi-Fi 6 probably won't be substantially faster. a single laptop Wi-Fi 6 connected to a router Wi-Fi 6 it can be a little faster than a single Wi-Fi 5 laptop connected to a Wi-Fi 5 router, for example.
The story starts to change as more and more devices are added to your network. Where current routers can start to get overwhelmed with requests from multiple devices, routers Wi-Fi 6 are designed to keep all devices up to date with the data they need.
The speed of each is not necessarily faster than what is achieved today on a high quality network, but they are more likely to maintain these maximum speeds even in the busiest environments. It's good for offices and public Wi-Fi networks, for example.
In the private realm, the scenario is equally positive: you can imagine this being useful in a home where a person is transmitting Netflix, another is playing games, another is video calling, and in between, a bunch of smart devices are working at full throttle – a lock, temperature sensors, light switches, and so on.
The max speeds of these devices don't necessarily increase, but the speed you see in typical day-to-day use will likely be optimised.
How can I purchase Wi-Fi 6? 3h576y
The answer is not the most encouraging: you will need to buy new devices. The generations of Wi-Fi rely on new hardware, not just software updates. Because of that, you will need to buy new smartphones and laptops to get the new version of the technology. New releases will have the new generation by default.
As you replace your smartphone, laptop, and video game console over the next five years, you're likely to bring home new devices that include the latest version of Wi-Fi.
There's one thing, though, you can't give up: a new router. If your router does not Wi-Fi 6, you won't get any benefit no matter how many compatible devices you bring home.
Again, this is not something that counts in the short term. But if your house is full of connected smart devices and things start to slow down in a few years, a router Wi-Fi 6 could help significantly.

There are two main technologies that speed up connections Wi-Fi 6: MU-MIMO e OFDMA.
The MU-MIMO, which literally means “multi-, multi-in, multi-out”, is already in use on modern routers and devices, but the Wi-Fi 6 updates it. The technology allows a router to communicate with multiple devices at the same time, rather than first broadcasting on one device and then broadcasting to the next.
Currently, MU-MIMO allows routers to communicate with four devices at a time. O Wi-Fi 6 will allow devices to communicate with up to eight.
You can think about adding MU-MIMO connections, like adding delivery trucks to a fleet, says Kevin Robinson, Marketing Leader for the Wi-Fi Alliance, a technology industry group that oversees the implementation of the Wi-Fi.
“You can send each of these trucks in different directions to different customers,” says Robinson. “Before, you had four trucks to fill with goods and ship to four customers. With Wi-Fi 6, you now have eight trucks.”
The other new technology, OFDMA, which literally means “orthogonal frequency division multiple access”, allows a stream to deliver data to multiple devices at once.
Extending the truck metaphor, Robinson says that OFDMA essentially allows a truck to load goods to be delivered to multiple locations.
“With OFDMA, the network can look at a truck and see, 'I'm only allocating 75% of this truck and this other customer is on its way,' and then fill the remaining space with a delivery to a second customer.” Robinson.
In practice, this is all used to get more out of every broadcast from a router to your device.

Another new advantage of Wi-Fi 6 allows devices to schedule communication with a router, reducing the time needed to keep their antennas on to transmit and search for signals. This means less consumption and improves battery life.
This is all possible due to a feature called Target Wake Time, authorizing the routers to schedule check-in with devices.
It won't be useful for everything, however. Your laptop needs constant internet access, so it's unlikely to make heavy use of this feature (except, perhaps, when it goes into sleep state).
Instead, this feature is more geared towards devices Wi-Fi smaller, low-power devices that need to update their status from time to time, such as smart home devices that are unused for most of the day.
Security is the middle name 735v2h
Last year, the Wi-Fi began receiving its biggest security update in a decade, with a new security protocol called WPA3.
O WPA3 it makes it harder for hackers to crack s, and it makes some data less useful than others, even if hackers manage to obtain it. It is worth ing that current devices and routers can this technology, but it is optional.
so that a device Wi-Fi 6 receive certification from Wi-Fi Alliance announcement, WPA3 necessary, therefore, most devices Wi-Fi 6 will likely already have this security system in place when the certification program is launched.
But this is just the beginning, see? 5k6jy
Devices that Wi-Fi 6 are starting to show up. You can already buy routers with the new technology, but so far they are expensive high-end devices.
Many laptops already include the new generation of Wi-Fi, but it is still not a market rule. O Wi-Fi 6 will begin arriving on high-end cell phones later this year.
The latest processor Qualcomm, Samsung Galaxy S10 It is one of the first smartphones on the market with the new processor and it also s the newest generation of Wi-Fi access.
The inclusion of Wi-Fi 6 will likely become even more common in the next year. THE Wi-Fi Alliance announcement will launch its certification program in the second quarter of 2019, which guarantees compatibility between devices Wi-Fi.
Devices do not need to certification, but their launch will mean that the industry is ready for the arrival of the Wi-Fi 6.
