Wi- Fi 6 - Overview


Wi- Fi 6 is the latest technology in the internet Universe. It helps you connect to the internet and makes sure you are connected to thefastest and the most efficient one. Faster internet is constantly in demand,especially as we consume more bandwidth-demanding apps, games, and videos with our laptops and phones. WI-Fi 6, also called 802.11ax, is an upgrade on the current highest-speed Wi-Fi protocol in wide use, 802.11ac. Wi-Fi 6 will get the new spectrum in 6 GHz Band in 2019 or 2020 for improved speed. It has the most effective and improved bands compared to the existing 2.4 GHz frequencies.

Major advantage with Wi-Fi 6 is its Wireless Density, that is it can coexist with multiple devices at a given vicinity which also means it has greater device density also increasing the speed of the connection simultaneously. The speed of Wi-Fi 6 would be 9.6 Gbps. The Wi-Fi 6 is 3.5Gbps faster than the Wi-Fi 5.  This will enable more potential speed for individual device in the network of devices the Wi-Fi is connected to.

Wi-Fi 6 introduces several devices which is eradicate the issues faced with putting dozens of the Wi-Fi devices on a single network. This facilitates connecting several devices all at once, lets routers send data to multiple devices in same broadcast and lets Wi-Fi devices schedule check-ins with the router. With these features the connections will become more stronger as several devices start demanding data. Unique feature of Wi-Fi 6 is that when connected to the single device it might be faster than the Wi-Fi 5 however only when multiple devices are connected the Wi-Fi 6 is more efficient, which means the efficiency is higher in busier environments. Consider a situation when at home someone is watching Netflix, another one is on a video call, other one is gaming and temperature sensors, door locks, light switches are connected all as well at once.

New standard improves performance by supporting deterministic packet scheduling which also increases the efficiency of the use of any given band, also improves the efficiency of the power utilization in mobile devices dramatically.

Office Networkers would find it more reliable and quicker to communicate in crowded offices. IoT device supporters can pack more low power devices into a space with limited access points. Wi-Fi 6 will eventually improve the experience of all the wireless users. It can also be used in Remote surgery devices making a breakthrough in the life safety applications because it is reliably deterministic and has great speed.

Wi-Fi 6 works on new hardware not only on software updates, which means it would need a Wi-Fi 6 router. New devices will come with the Wi-Fi 6 by default, like Wi-Fi 6 compatible. This isn’t something worth rushing out and buying. But if your home is packed with Wi-Fi-connected smart devices, and things start to get sluggish in a couple years, a Wi-Fi 6 router may be able to meaningfully help.

Two key technologies speeding up Wi-Fi 6 connections: MU-MIMO and OFDMA. MU-MIMO, which stands for “multi-user, multiple input, multiple output,”is already in use in modern routers and devices, but Wi-Fi 6 upgrades it. The technology allows a router to communicate with multiple devices at the same time, rather than broadcasting to one device, and then the next, and the next.Right now, MU-MIMO allows routers to communicate with four devices at a time. Wi-Fi 6 will allow devices to communicate with up to eight. The other new technology, OFDMA, which stands for “orthogonal frequency division multiple access,” allows one transmission to deliver data to multiple devices at once.this is all used to get more out of every transmission that carries a Wi-Fi signal from a router to your device.

Devices supporting Wi-Fi 6 are just starting to trickle out. You can already buy Wi-Fi 6 routers, but so far, they’re expensive high-end devices. A handful of laptops include the new generation of Wi-Fi, too, but it’s not widespread just yet.

Wi-Fi 6 will start arriving on high-end phones this year, though. Qualcomm’s latest flagship processor, the Snapdragon 855, includes support for Wi-Fi 6, and it’s destined for the next wave of top-of-the-line phones. The Snapdragon 855’s inclusion doesn’t guarantee that a phone will have Wi-Fi 6,but it’s a good sign: Samsung’s Galaxy S10 is one of the first phones with the new processor, and it supports the newest generation of Wi-Fi.

The inclusion of Wi-Fi 6 is likely to become even more common next year. The Wi-Fi Alliance will launch its Wi-Fi 6 certification program this fall, which guarantees compatibility across Wi-Fi devices. Devices don’t need to pass that certification, but its launch will signify that the industry is ready for Wi-Fi 6’s arrival.
