The Difference Between Wireless-N, Wireless-AC, Wireless-AD, Wi-Fi 6, and Wi-Fi 6E

Are you one of those people constantly asking: Why is my Internet or Wi-Fi so slow? Most people generally refer to all Wireless Internet as Wi-Fi, but Wi-Fi is an oft misused term. Many are quick to blame their ISP for all of their internet problems. However, many times it all comes down to the type of router you are using and the speed it offers. Read on to see why you should ditch that old Wireless-N router and upgrade to a super-fast Wireless AC or a Wi-Fi 6 router!

Wireless Standards From Wireless-N to Wi-Fi 6

The wireless standard that we know today was created by the Institute of Electrical and Electronics Engineers or IEEE.

IEEE 802.11 is a wireless networking standard created to keep manufacturers of wireless routers and wireless networking devices (PlayStations, Laptops, Tablets, SmartTVs, Xboxes, iPhones, Roku) on the same page. These standards include IEEE 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ad, and 802.11ax. So, what are these standards, and what do they have to do with you?

What Is Wireless-G? How Fast Is Wireless-G?

Wireless-G, also known as 802.11g, is an older wireless networking standard set by the IEEE. Mostly obsolete now, 802.11g offered speeds of up to 54 Mbps and was quickly adopted due to its upgrade in speed over 802.11b.

For example, you may notice that the speed in many coffee shops seem quite slow. This is because man run on slower Wireless-G (54 Mbps) routers, or even Wireless-B (11 Mbps). As a result, when so many people are constantly sharing the same connection, you get relatively low throughput speeds.

Do People Still Use Wireless-N?

Wireless-N, also known as Wi-Fi 4, was created to improve network throughput (maximum speed and transmission capabilities) over the two prior standards—802.11b and 802.11g.

Wireless-N was a significant upgrade from Wireless-G for the following reasons:

While these features may have been an upgrade from Wireless-G, Wireless-N is mostly phased out. Luckily, new routers and wireless standards will still support Wireless-N and older wireless standards.

What About Wi-Fi 5 / Wireless-AC?

Wi-Fi 5, also known as Wireless-AC, is one of the IEEE’s most popular wireless standards on the market today. The 802.11ac standard greatly improves nearly every aspect of Wireless-N.

Wireless-AC has increasingly become more formalized and is essentially the minimum for every wireless-capable device. Some improvements include:

What is Wireless-AD?

Wireless-AD is among the newer wireless standards to hit the consumer market. As with any new wireless standard, nearly every aspect has been improved and upgraded. Some of these upgrades include:

However, Wireless-AD is not backward compatible. Simply put, there are few very Wireless-AD compatible devices that support the new 60 GHz frequency band.

What is Wi-Fi 6 or Wireless-AX?

Wi-<a href=Fi 6 is the same as 802.11ax" width="200" height="200" />

Unveiled at CES 2018, Wi-Fi 6, also known as Wireless-AX, is the next step in wireless standards. Wi-Fi 6 can deliver as much as five times the bandwidth as Wi-Fi 5. Current routers are equipped with 4×4 MU-MIMO (multi-user, multiple-input, and multiple-output), while wireless-AX Wi-Fi 6 routers will come standard with 8×8 MU-MIMO on both 2.4 GHz and 5 GHz bands. Essentially, Wireless-AX will support eight data streams up and down your network, doubling the previous standard.

Other upgrades from previous standards include: increased efficiency, reliability, and better coverage in large areas. While these specs sure do look enticing, Wi-Fi 6 routers are generally more expensive and are less customizable than Wi-Fi 5 routers. Additionally, these are mostly software upgrades and not a 6Ghz band as most anticipated.

Why You Should Upgrade To Wi-Fi 5 or Wi-Fi 6

Hanging onto an older Wireless-G or Wireless-N router means you are sacrificing overall speed and security while actually hindering the wireless capabilities for newer devices.

Using a Wireless-G or Wireless-N router with your iPad may feel like trying to catching a fish with a stick. It may work, but you’ll feel like you’re back on dialup! New wireless standards mean MAJOR wireless connectivity improvements. Best of all, newer routers are fully backwards compatible with older devices, so you’ll always be able to connect every device to the internet!
