What is Wifi 6 ?

This is new standard set by IEEE (802.11ax standard) for wifi which speed range will be 9.6Gb/s which is maximum from all available standard so far.

 

Note: IEEE is acronym of "Institute of Electrical and Electronics Engineers" and this is not a University nor a collage but a nonprofit "Professional Association" which formed in 1st january 1963 located at Manhattan, NewYork(USA).

 

Note: IEEE is formed after merger of "American Institute of Electrical Engineers" and the "Institute of Radio Engineers".

 

Key Points:

• It Uses 6GHz frequecy. (More frequency means More Speed).
• low latency.
• longer signal range.
• lower power consuption copare to wifi 5, it mean less battery drainage.
• It uses fourteen 80Mhz and two 160MHz frequency in bandwith configuration.
• In Wifi6 (6GHz), Wi-Fi traffic is more secure than ever.
• It uses mandatory Wi-Fi Protected Access 3 (WPA3) security controls.
• Wifi6 (6GHz) networks are more difficult to hack.
• More available WiFi channels means more available WiFi spectrum and less overlap between networks in crowded areas (eg. mall).
• Wifi 6 networks don’t have to slow down to accommodate older devices. This means that WiFi 6E devices can take full advantage of the bandwidth, spectrum, and speed improvements of 6GHz without competing with any non-6E devices.
• Main benefits to have Wifi 6 is to avoid congestion, The low number of Wi-Fi channels available today forces many users to share available bandwidth and creates congestion.

 

What is Wifi 6E ?
This is advance from Wifi 6 which uses only two 160MHz channel But Wifi 6E uses total seven 160MHz channel and fourteen 80Mhz channel. This gives Wifi 6E devices the advantage to experience Gigabit speeds more easily.

 

 

 

Wifi Generations..

Before this there was

• Wifi 5 (802.11ac std.) with speed limit of 3.5Gb/s and
• Wifi 4 (first officially used term in 2018 by IEEE) (802.11n std.) with speed limit of 600Mb/s and
• Wifi 3 (this term has not officially used) (802.11g std.) with speed limit of 54Mb/s and
• Wifi 2 (this term has not officially used) (802.11b std.) with speed limit of 50Mb/s. and
• Wifi 1 (this term has not officially used) (802.11a std.) with speed limit of 11Mb/s.

 

 

Why we need Wifi 6 ?
The average speed of 4G is 30Mb/s and of 5G is 60Mb/s. But as we can see that wifi5 (even Wifi4 too) has capability to bear speed of 5G, then why we need Wifi 6?

 

Note: New upcomming Wifi 7 has 802.11be standard which is now in development phase.
