We use WiFi on a regular basis, however just a few of us are well-versed with its naming conference. For, there are too many variations of WiFi, and the naming scheme is utter technical jargon that’s onerous to know and keep in mind for many who aren’t intently concerned with know-how. Nevertheless, that’s about to vary quickly.
Apparently, with WiFi Alliance (a corporation that promotes WiFi know-how and certifies WiFi merchandise) adopting a brand new naming conference, it will be a lot simpler for widespread individuals (with a restricted understanding of know-how) to grasp and differentiate the totally different WiFi variations and assist themselves make an knowledgeable choice when purchasing for a networking system.
Till now, the WiFi naming conference has been based mostly on the 802.11 protocol – a household of specs for wi-fi native space networks (WLANs) developed by the Institute of Electrical and Electronics Engineers (IEEE), and subsequently, the requirements 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac. Based mostly on this present naming conference, the subsequent era of WiFi ought to have ideally been 802.11ax. Nevertheless, as an alternative of denoting the brand new WiFi normal as 802.11ax, the WiFi Alliance has determined to name it WiFi 6, to keep away from confusion and make it simpler for widespread individuals to know. With the brand new number-based naming conference, the earlier two requirements, specifically the 802.11n and 802.11ac, will now be denoted as WiFi four and WiFi 5. Though, this naming conference doesn’t prolong additional again to the sooner requirements, however to make some sense, right here’s how all the lineup seems like underneath the brand new naming convention-
- 802.11a – Wi-Fi 1
- 802.11b – Wi-Fi 2
- 802.11g – Wi-Fi three
- 802.11n – Wi-Fi four
- 802.11ac – Wi-Fi 5
- 802.11ax – Wi-Fi 6
What’s WiFi 6 (802.11ax)?
WiFi 6 is the sixth-generation of WiFi normal, and for probably the most half, in contrast to some other earlier generations of WiFi alleged to make WiFi networks quicker, extra dependable, and extra power environment friendly. The highlighting issue about this new normal is that starting this era, WiFi Alliance has determined to maintain issues easier and quit on the prevailing alphanumeric naming conference to a a lot easier numeric scheme. And subsequently, denoting the sixth-generation as WiFi 6 and never 802.11ax.
Aside from only a change within the naming conference, WiFi 6 additionally comes with a rise in community capability, offering larger switch charges, and enhancements in energy effectivity.

WiFi 6 Tech
To perform this, WiFi 6 makes use of applied sciences like MU-MIMO (Multi-Consumer A number of Enter, A number of Output) and OFDMA (Orthogonal Frequency Division A number of Entry). Which signifies that, even when there are a whole lot of units in your community, you’ll nonetheless retain quicker speeds with comparatively a lot much less latency. In a nutshell, you’ll have a a lot better expertise with WiFi 6, regardless of the variety of related units, as in comparison with older generations.
As per the Wi-Fi Alliance, a WiFi 6 entry level can be able to dealing with numerous units on the similar time with the MU-MIMO and OFDMA know-how. Utilizing MU-MIMO, a router will be capable of serve numerous customers whereas permitting them to switch extra knowledge at a time, concurrently. Nevertheless, WiFi 6 shouldn’t be the primary model to make use of MU-MIMO. Prior to now, different Wi-Fi requirements have additionally leveraged this know-how to serve a number of customers with high-speed knowledge switch. However, with WiFi 6, the know-how has obtained some vital enhancements, that are fairly obvious as per the claims.
However, the OFDMA know-how is an enchancment over the Orthogonal Frequency Division Multiplexing (OFDM) know-how, used with older requirements. Because the identify suggests, this know-how provides a number of entry with simultaneous knowledge transmission from a number of customers directly. Nevertheless, one disadvantage with OFDM know-how is that it may possibly trigger some critical latency points. To eradicate this drawback, OFDMA comes into the image, which permits an AP (Entry Level) to schedule knowledge transmission and additional divide frequencies in an effort to transmit knowledge to/from a number of shoppers on the similar time. In a means, this enables extra units to function on a channel by decreasing the latency, and in flip, growing effectivity.
WiFi 6 Safety
Along with subduing latency, WiFi 6 additionally presents improved safety with help for WPA3 (Wi-Fi Protected Entry three). For the uninitiated, WPA3 is the third-generation normal for safe wi-fi pc networks. It makes use of 128-bit encryption in WPA3-Private and 192-bit in WPA3-Enterprise mode and replaces the PSK (Pre-Shared Key) change with a safer preliminary key trade. Based on the Wi-Fi Alliance, the WPA3 normal will alleviate safety points triggered as a consequence of weak passwords and in addition assist in simplifying the method of establishing units.
What are some WiFi 6 purposes?
For probably the most half, plenty of the WiFi 6 purposes are just like the present purposes, besides, the WiFi 6 goals to supply some vital enhancements over older variations. To start with, along with offering a quicker and extra dependable residence community and interference-free public Wi-Fi expertise, WiFi 6 guarantees advantages on the IoT hardware entrance – with improved battery efficiency and improved vary – and elevated efficiency with lowered latency on in-vehicle techniques.
What are the variations between WiFi 6 and 5G?
5G is one other wi-fi know-how that’s going to return out this yr. And with that, lots of people are confused with the variations and similarities that it shares with WiFi 6. So to interrupt it down, listed here are a number of the widespread features and variations between the 2 wi-fi applied sciences.
Speaking about similarities, each WiFi 6 and 5G, declare to supply quicker speeds and efficiency enhancements over their earlier generations. Additionally they overlap on a couple of elementary applied sciences like Beamforming and MU-MIMO. Nevertheless, aside from that, the 2 have some vital variations, just like the scope of use, compatibility, and availability.
With WiFi 6, customers get what known as a WLAN (Wi-fi Native Space Community), which supplies entry to quicker web speeds indoors (house, workplace, public areas and so on.). Whereas with 5G, customers get a WAN (Large-Space Community), which gives a cellular expertise that permits them to take pleasure in quicker speeds on the go together with purposes that stretch in the direction of edge computing and IoT (Web of Issues).
One other distinctive distinction between the 2 wi-fi applied sciences is when it comes to the vary of units that it might help. With WiFi 6, the Wi-Fi Alliance has primarily modified the nomenclature to make it straightforward for regular individuals to know and differentiate the newer era.
