We talked about Wi-Fi a couple weeks ago. Let’s expand on that. Now they have given Wi-Fi version numbers for the different protocol types identified by the letter suffix on 802.11. Let’s start with 802.11 and what it is.
The 802.11 protocol is set forth by the IEEE (Institute of Electrical and Electronics Engineers, Inc.) They are the ones who set the standards of what is under each protocol, specifically the IEEE 802.11™ Wireless Local Area Networks, the working group for WLAN standards. They have regular sessions and presentations about 802.11 protocol. There is one being held right now in Bangkok, Thailand.
The Wi-Fi Alliance® has now assigned version numbers to different Wi-Fi protocols.
- Wi-Fi 6, which will be available next year will be 802.11ax standard.
- Wi-Fi 5 is the 802.11ac standard
- Wi-Fi 4 is the 802.11n standard
Older standards are not being given a version number because they are not widely used anymore.
Wi-Fi Certified WiGig™ will bring bands of 60 GHz with multi-gigabit speeds, suitable for virtual reality and HD streaming. Wi-Fi security WPA3™ will have increased crytographic strengths.
