Explained WiFi 6 the next wireless technology new WiFi naming system

Explained WiFi 6 the next wireless technology new WiFi naming system
The next generation of Wi-Fi, based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11ax standard, is Wi-Fi 6

The Wi-Fi Alliance is the community that sets standards for the Wi-Fi industry.

Wi-Fi technology has evolved and improved over the last 21 years – from only a few megabits to several Gigabit speeds – yet this information is currently not provided. With Wi-Fi 6, consumers can easily identify the level of Wi-Fi provided and demand superior services.

Wi-Fi Alliance introduces Wi-Fi 6 as the industry designation for products and networks that support the next generation of Wi-Fi , based on 802.11ax technology.
Wi-Fi 6 is part of a new naming approach by Wi-Fi Alliance that provides users with an easy-to-understand designation for both the Wi-Fi technology supported by their device and used in a connection the device makes with a Wi-Fi network.

The new naming system identifies Wi-Fi generations by a numerical sequence which correspond to major advancements in Wi-Fi.
The generation names can be used by product vendors to identify the latest Wi-Fi technology a device supports, by OS vendors to identify the generation of Wi-Fi connection between a device and network, and by service providers to identify the capabilities of a Wi-Fi network to their customers.

The generational terminology may also be used to designate previous Wi-Fi generations, such as 802.11n or 802.11ac. The numerical sequence includes:

a-Wi-Fi 6 to identify devices that support 802.11ax technology

b-Wi-Fi 5 to identify devices that support 802.11ac technology

c-Wi-Fi 4 to identify devices that support 802.11n technology

The upcoming 802.11ax standard is expected to be 30% faster than 802.11ac, and is due for final approval next year.

To help users identify devices that provide the latest Wi-Fi experience, Wi-Fi Alliance has introduced simplified generational names that may appear in device names and product descriptions. Wi-Fi devices supporting the latest generation of connectivity are based on the 802.11ax standard and are known as Wi-Fi 6 devices.
Wi-Fi 6, based on the IEEE 802.11ax standard, enables next generation Wi-Fi connectivity. Wi-Fi 6 will provide the capacity, coverage, and performance required by users—even in dense environments such as stadiums and other public venues. Wi-Fi 6 networks enable lower battery consumption in Wi-Fi 6 devices, making it a solid choice for any environment, including smart home and IoT uses.

WiFi 6 will greatly improve performance at crowed places , open public places

According to the Wi-Fi Alliance, Wi-Fi 6 will feature higher data rates, increased capacity, and could be offering brilliant performance in dense environments.
Each generation of Wi-Fi offers new features – faster speeds, increased throughput, and better experiences. Industry adoption of the new terminology will help users better understand the experience they can expect.

WiFi New Names , the new naming system will make it very easy for everyone to know the product which they are buying is using old technology or new technology.
Now you will not need to study the all the features of router or any wireless device , just check the number if it is WiFi 5 it is not very old is good if router says WiFi 6 means router is latest means provided best available features.

Wi-Fi 1, Wi-Fi 2, and Wi-Fi 3  aren’t widely in use

Wi-Fi 1 -802.11b -1999
Wi-Fi 2 -802.11a -1999
Wi-Fi 3 -802.11g -2003
Wi-Fi 4 -802.11n -2009
Wi-Fi 5 -802.11ac -2014
Wi Fi 6- 802.11ax – 2018

Wi-Fi 6 will deliver an improved experience to address device and application needs in a range of consumer and enterprise environments. The generational terminology is expected to be widely adopted by the Wi-Fi ecosystem.

The sixth generation of Wi-Fi - 802.11ax - is the most advanced ever, bringing faster speeds, greater capacity and coverage, and will make the user experience even more enjoyable.  This simple, generational representation will let consumers differentiate phones and wireless routers based on their Wi-Fi capabilities, helping them pick the device that suits their needs best. When they see that their device contains Wi-Fi 6, they will know that they have the best wireless connectivity on the market.
Key benefits of Wi-Fi 6 technology include -
a-Higher data rates
b-Increased capacity
c-Good performance in dense environments
d-Improved power efficiency

New capabilities -
a-Uplink and downlink orthogonal frequency division multiple access (OFDMA) increases efficiency and lowers latency for high demand environments 
b-1024 quadrature amplitude modulation mode (1024-QAM) enables peak gigabit speeds for emerging, bandwidth-intensive use cases
c-Improved medium access control (MAC) control signaling increases throughput and capacity while reducing latency
d-Increased symbol durations make outdoor network operations more robust 

How WiFi 6 will increase wireless speed ?

IEEE 802.11ax is an evolutionary improvement to 802.11ac.
One of the goals of 802.11ax, also known as highefficiency wireless (HE), is to deliver higher levels of efficiency in existing Wi-Fi networks:
1- Deliver high data rates more consistently in typical Wi-Fi environments
2-Focus on Key Performance Indicators (KPI) that improve Quality of Experience (QoE)

In the traditional enterprise space, the challenges include:
1-Ultra-High-Density (UHD) environments with scores of users each carrying or wearing three or four 802.11 clients, all consuming network resources concurrently
2-The increased adoption of real-time applications such as 4K video and augmented or virtual reality (AR/VR) placing
new demands on already pressured environments

Wi-Fi 6 will improve speed  through more efficient data encoding, resulting in higher throughput. Mainly, more data is packed into the same radio waves. The chips that encode and decode these signals keep getting more powerful and can handle the extra work.

Intel trumpets that Wi-Fi 6 will improve each user’s average speed by “at least four times” in congested areas with a lot of connected devices.

Wi-Fi 6 can now divide a wireless channel into a large number of subchannels. Each of these subchannels can carry data intended for a different device. This is achieved through something called Orthogonal Frequency Division Multiple Access, or OFDMA. The Wi-Fi access point can talk to more devices at once.

WiFi 6 also has improved MIMO—Multiple In/Multiple Out. This involves multiple antennas, which let the access point talk to multiple devices at once.

With Wi-Fi 5, the access point could talk to devices at the same time, but those devices couldn’t respond at the same time. Wi-Fi 6 has an improved version of multi-user or MU-MIMO that lets devices respond to the wireless access point at the same time.

Wireless access points near each other may be transmitting on the same channel. In this case, the radio listens and waits for a clear signal before replying. With Wi-Fi 6, wireless access points near each other can be configured to have different Basic Service Set (BSS) “colors.” This “color” is just a number between 0 and 7. If a device is checking whether the channel is all clear and listens in, it may notice a transmission with a weak signal and a different “color.” It can then ignore this signal and transmit anyway without waiting, so this will improve performance in congested areas, and is also called “spatial frequency re-use.”

Wi-Fi 6 is going to be backwards compatible with all the existing wifi gear out there
Wi-Fi devices may also use a user interface (UI) icon on the display to identify the generation of a network connection. The icons will display a Wi-Fi signal indicator and a numerical representation of the connection. Icons will adjust as users move between Wi-Fi networks that provide a different user experience. When a user device displays a signal indicator icon accompanied by the number 6, indicating a Wi-Fi 6 connection, that device is utilizing the most advanced version of Wi-Fi available.
