While upgrading to a Wi-Fi 6 router can provide significant benefits, it is crucial to assess your specific needs and the devices you currently use to determine if it is necessary for you to replace your existing router.
Wifi 6 was released, promising significant speed improvements on electronic devices such as phones, tablets, … compared to previous generations of wifi, so what is Wifi 6, and what features does it have? outstanding, let’s find out!
What is Wifi 6?
Wi-Fi 6 is the latest update to the wireless networking standard. Wi-Fi 6 is based on the IEEE 802.11ax standard , with faster speeds, greater capacity , and improved power efficiency than previous wireless connections.
Compared to previous wireless connections, Wifi 6 has been renamed to make it easier for users to remember and understand the latest update for this wireless standard.
According to the old naming standard, Wifi 5 will be 802.11ac, and Wifi 6 will be 802.11ax. So the difference between Wifi standards is in the name behind ax/ac/n/…, and this name is quite complicated and easy to confuse users, so the new name, Wifi 6 is shorter than official. was born.
Each generation of wifi offers new features – faster speeds , increased throughput , and a better experience. Wifi 6 will bring an improved experience to meet the needs of the ever-evolving IT industry.
It is known that this new name Wifi 6 will be officially applied from 2019.
What’s new in Wifi 6 compared to the old wifi?
Significantly improved speed
Wifi 6 delivers speeds of up to 10Gbps , and reaches 12Gbps at the highest wireless frequency and over very short distances. This is a pretty big improvement in speed ( an increase of 30-40% compared to the old Wifi 5 standard).
Better radio frequency, more channels
Another outstanding feature of Wifi 6 is orthogonal frequency division multiple access – OFDMA. OFDMA uses 2 available transmission frequencies: 2.4GHz and better 5GHz. This upgrade increases speed by dividing the available spectrum into smaller units , thereby increasing throughput and network performance.
Currently, conventional dual-band routers operate on the 2.4GHz and 5GHz spectrum. In which, these spectrums are distributed according to the set of channels with a width of 20MHz.
Wi-Fi 6 changes this allocation of 20MHz channels to 256 individual sub-channels , which is a significant increase, compared to the current 64 channels. Not only increasing the number of pure channels , Wi-Fi 6 also modifies the data connections in the added channels .
More concurrent threads, better performance in crowded areas
Wifi 6 is an update to the current 256 Quadrature Amplitude Modulation (QAM) 802.11ac feature. Wi-Fi 6 increases to 1024 QAM, allowing up to 8 simultaneous streams to broadcast. This means that a particular access point can handle traffic up to 8 users at the same time at the same speed without any drop in speed.
This is a great solution for network congestion often seen in businesses. The performance of this new type of wifi is also better in densely populated areas.
Longer battery life for connected devices
With the “target wake time” (TWT) feature, smartphones, laptops and other devices connected to wifi will have longer battery life .
When the access point interacts with a device, it can tell the device exactly when to put its Wi-Fi signal to sleep or when to wake it up to receive the next transmission.
This will save power and the wifi radio can spend more time in sleep mode , resulting in longer battery life.
Do you need a new router to use Wifi 6?
The decision to buy a new router to support Wifi 6 is really necessary, but at the moment, this is a rather difficult decision when there are very few devices on the market that support Wifi 6 connectivity.
The introduction of Wifi 6 led to the impending arrival of WPA3, the new wireless security protocol . Widespread adoption of WPA3 won’t spread quickly until late 2019.
So check to see if the router you are about to buy can receive firmware updates to the more secure WPA3 standard.
A few Wifi 6 routers have started to appear on the market, such as ASUS’ TR-AX88U which is advertised as ready to support next generation 802.11ax devices, using the AX6000 router standard , compliant with the New and best wireless specs.
Netgear’s Nighthawk AX8 is another Wifi 6 router that can be purchased at the moment. The AX8 has a sleek face and the future promises to be a router with the same specification as the AX6000.
Both the Netgear Nighthawk AX8 and Asus TR-AX88U have throughput limits of around 6Gbps , and have yet to hit the peak of Wi-Fi 6 (around 10Gbps). This speed can only be achieved on routers that meet the AX11000 standard.
In particular, TP-Link’s high-end Archer router brand will have the AX11000 router product in the near future.
