Are you lost in the maze of Wi-Fi protocols? This article will explain the differences between Wi-Fi 6, Wi-Fi 6E, & previous wireless protocols. To sum it all up, say "Wi-Fi." The accuracy is high, in a way. It details one specific approach to establishing an online presence.

Wi-Fi protocols come in a wide variety. Different wireless protocols are used by your router, laptops, tablets, smartphones, and smart home devices. Standards for wireless technology also undergo periodic updates. Internet speeds, connection quality, the number of users that can connect simultaneously, etc., all improve with each update.

The problem is that the sheer variety of wireless specifications and standards is complex for the average person to understand. Here is a comprehensive list of Wi-Fi specifications.

An Explanation of Wi-Fi Protocols and Standards

To define how the Wi-Fi connection (and other data transmission networks) should function. Wireless standards have been developed.

IEEE 802.11 WLANs and Mesh networks are the most widespread wireless protocols you're likely to encounter. You might check out https://firstworldneeds.com/ to know more in detail about the Wi-Fi protocols. Wi-Fi 802.11 receives revisions every few years from the IEEE. As of this writing, 802.11ac is the most popular Wi-Fi standard. But the next-generation standard, 802.11ax (also known as Wi-Fi 6 and Wi-Fi6E—but enough on this in a bit! ), is gradually becoming more widespread.

The next-generation standard, IEEE 802.11be, is expected to debut around 2024–2025. (using the name Wi-Fi 7).

The Evolution of Wireless Standards

In some instances, older Wi-Fi protocols may still be helpful. Certainly not at this time. Here's a quick rundown of how Wi-Fi standards came to be and whether they're still in use today.

IEEE 802.11:

The first! This obsolete standard, introduced in 1997, allowed a maximum internet speed of 54 Mbps (Mbps). It's been nearly a decade since this technology was produced, and it's incompatible with modern machinery.

IEEE 802.11a:

This Wi-Fi model, first released in 1999, operates in the 5GHz frequency range. Since many other devices (including the vast majority of wireless phones) also utilize the 2.4GHz band. This was done in the hopes of experiencing less interference. Data speeds for 802.11a may reach up to 54 Mbps, making it a fast option. However, obstacles in the signal channel reduce the range of devices operating at 5GHz, making them less effective overall.

IEEE 802.11b:

Another standard from 1999 operates at up to 11Mbps on the more common 2.4GHz range. The widespread use of Wi-Fi may be traced back to 802.11b, the specification that set the bar for wireless networking.

IEEE 802.11g:

The 802.11g standard was developed in 2003 and increased the maximum data rate to 54Mbps while still operating on the tried-and-true 2.4GHz range. Because of this, the standard quickly gained popularity and became the norm.

IEEE 802.11n:

Although it was released in 2009, not many people upgraded right away. 802.11n uses both the 2.4 GHz and 5 GHz bands and may use several channels simultaneously. It is considering that the maximum throughput of the standard is 600Mbps and that each channel supports up to 150Mbps. The maximum throughput of the standard is 600Mbps.

Technical Specification for IEEE 802.11ac

At present, most wireless devices adhere to the ac standard. Initiated in 2014, ac significantly boosts the data speed for Wi-Fi devices to a max of 1,300 Mbps. More 5GHz Wi-Fi broadcast channels and the ability to use multiple antennas. With a single router are two more improvements the ac standard brings.

IEEE 802.11ax

In the future, your wireless router and other devices will conform to the axe standard. Theoretical network capacity will increase to 10Gbps when 802.11ax rolls out—representing an increase of 30–40 percent above the ac standard. In addition, by enhancing MU-MIMO and enabling more concurrent data streams. The wireless axe will expand network capacity.

IEEE 802.11be:

Although 802.11be has not yet published its standards, it is expected to replace 802.11ax. Doubled bandwidth, as well as the increasing amount of spatial streams. That combined allows data speeds as high as 40 Gbps, as stated in the IEEE Xplore report, which 802.11be will provide.

Is it possible for different Wi-Fi standards to talk to one another?

In a Wi-Fi network, any two devices that use the same standard may talk to each other without problems. However, problems may develop when attempting to link gadgets that employ incompatible wireless protocols.

  • These days, your router can get along OK with 802.11ac devices.

  • An ac router is backward-compatible with older Wi-Fi standards to connect 802.11b, g, or n devices.

  • There is no way for 11b to contact 11a and vice versa.

  • To put it another way, 11g and b do not have a two-way communication channel.

While 802.11a and b are still in use, the initial 1997 standard (now called 802.11 legacies) is on its way out.

Wi-Fi protocols have been around for a while. Conflicts in the Software

If you have a wireless router at home, you may buy a new gadget with the confidence that it will automatically connect to your network. Not valid if your router is older and only supports the older Wi-Fi standard.

Just like if you were using a modern gadget.

For instance, just because you have brand new 802.11ac routers. To cover every nook and cranny with Wi-Fi doesn't imply that your older gadgets are automatically upgraded. However, you'll enjoy the router's extended range and other perks. Your Internet speed will be limited to that of the device's Wi-Fi standards. Your gadget will only connect to and send data through the n standard if it supports 802.11n.

To what extent is Wi-Fi 6 superior to its predecessors?

Wi-Fi 6 refers to the wireless naming system developed by the Wi-Fi Alliance. According to the Wi-Fi Alliance, 802.11 jargon only serves to confuse users. They have a point; users aren't given much to work with when only one or two letters are changed.

Parallel to the IEEE 802.11 standard is the Wi-Fi Alliance name scheme. The relationship between the two sets of rules for naming things is as follows:

  • Wi-Fi 6E: 11ax (2021)

  • Using Wi-Fi 6: 11ax (2019)

  • Wi-Fi 5: 11ac (2014)

  • Wi-Fi 4: 11n (2009)

  • Wi-Fi 3: 11g (2003)

  • Wi-Fi 2: 11a (1999)

  • Wi-Fi 1: 11b (1999)

  • Succession: 11 (1997)

How Does Wi-Fi 6E Work?

In 2020, Wi-Fi 6 became the de facto standard for wireless networking. By the end of the year 2020, however, another "new" norm was gaining steam.

Wi-Fi 6E is an upgrade to the previous standard. The new 6GHz band is now available, thanks to the upgrade.

In the past, only the 2.4GHz and 5GHz frequencies were available in Wi-Fi networks. Each of the two frequency bands is further subdivided into smaller channels. Thus they are both heavily used, for instance, in a multi-unit dwelling. Several Wi-Fi access points may be trying to use the same channel to broadcast.

Not that whatever you type will suddenly appear on your neighbor's PC, either. In today's packet-switched internet, that wouldn't be possible. However, it can negatively affect Wi-Fi speeds, especially in crowded places.

Wi-Fi 6E adds a massive amount of bandwidth to existing networks. By generating 14 additional 80MHz channels and seven new 160MHz channels. With less Wi-Fi interference, consumers in crowded regions will have access. To significantly more accessible bandwidth. In a nutshell, Wi-Fi 6E practically doubles the available bandwidth for your network.

So, when exactly new Wi-Fi 6E routers are available for purchase? In 2021, we may expect to see the first Wi-Fi 6E-enabled routers. Netgear is one of the pioneers in this space.

Now is the time to lock down your wireless router.

In addition to the speed boost, there are several advantages to upgrading to the most recent Wi-Fi standard. Knowing the differences between the different Wi-Fi protocols makes it easier to upgrade your router.
