Names and History

Before we dive deeper into this post, we’d like you to understand the history and names of each Wi-Fi standard we’ll be talking about. The reason for this will become evident as we go deeper into the dual-band vs. tri-band discussion.

– Names

Until recently, Wi-Fi standards used an arcane naming method to distinguish between the most recent and faster standards and their predecessors. The Wi-Fi Alliance used names like 802.11n, 802.11ac, and more to tell which standard was faster.

This naming scheme was confusing, and the Wi-Fi Alliance opted for a simple naming system that uses version numbers. Now, the previous Wi-Fi generation, 802.11ac, is known as Wi-Fi 5.

The current generation after Wi-Fi 5, previously known as 802.11ax, is now Wi-Fi 6, and the latest generation, an extension of 802.11ax, is called Wi-Fi 6E.

– The Invention of Wi-Fi

To understand the differences between dual-band vs tri-band routers, you must first know how they were made.

The creation of a committee known as the 802.11 led to the invention and release of Wi-Fi in 1997. Afterward, the IEE802.11 was created, a set of standards to define the communication between wireless area networks, otherwise known as WLANs.

With the standard in place, a basic Wi-Fi specification that allowed wireless devices to transfer two megabytes of data per second between each other was made.

This development led to the invention of prototype equipment that allowed users to meet the IEE802.11 standard. The prototype equipment would eventually become routers, and in 1999, Wi-Fi became available for home use.

– Understanding Wi-Fi Frequencies

Wi-Fi runs on two significant frequencies: the 2.4GHz frequency and the 5GHz frequency. The 2.4GHz frequency uses the 802.11b standard, while the 5GHz uses the 802.11a standard, which wasn’t very fast when it was created, as it is today.

For many years, the 2.4GHz frequency was the go-to option for Wi-Fi users. It was less expensive than 802.11a, had a more extended range, and worked with almost all mainstream devices.

– Becoming Better and Faster

In 2003, 802.11g was created. It was a combination of the faster speeds and longer range offered by the previous Wi-Fi standards. Routers had become better, too; they were becoming more powerful and offering better coverage. Wired connections were starting to fade out as Wi-Fi was beginning to catch up to the speeds they provided.

– What Changed Everything: The 802.11n Standard

The year 2009 came around, and the 802.11n (also known as Wi-Fi 4) standard was created. It was faster and even more efficient than the standards before it. The increase in efficiency led to the invention of ‘multiple input multiple output‘ data, otherwise known as MIMOs.

MIMOs use multiple antennas to make the communication between the receiver and the antenna stronger and better. Users were able to transmit and utilize more data without needing to get higher bandwidth.

– Too Much Fan Love

The 2.4GHz popularity meant that more users were using the channel. Every device, from Bluetooth devices to baby monitors, was using the same frequency. This demand led to the band becoming slower, and users had no choice but to look towards the short-range 5GHz channel.

– The Advent of Dual-Band Routers

Dual-band routers were invented to resolve the overcrowding on the 2.4GHz channel. They were designed with two types of wireless radios that could support both 5GHz and 2.4GHz frequencies at the same time.

Dual-band wireless routers were also made, so the devices close to the routers automatically connected to the 5GHz band. Devices behind walls or at a longer range connected to the 2.4GHz, which served as backup.

This setup reduced the load on 2.4GHz and got more users on the 5GHz frequency.

– Trying to Get More Users Onboard

In 2012, the 802.11ac standard was created. It focused on making the 5GHz band better and faster so more users could join and make the 2.4GHz frequency less crowded. That is why today, 802.11ac has four times the speed of what you get on 802.11n.

Also, 2012 was when the Beamforming concept was introduced as 802.11ac could support multiple antennas, allowing users to send data faster and efficiently.

Usually, when you send data or transmit a signal via wireless channels, the data spreads in all directions hoping to reach the target device. Beamforming focuses the data transmission and signals on the target device, allowing for a faster and reliable connection.

What Are Dual-Band Routers

As we noted earlier, dual-band routers were designed to bring more users to the 5GHz channel. The 2.4GHz channel gets a lot of interference since too many devices, such as Bluetooth gadgets, smartphones, and even home appliances like microwaves, use the channel. It’s just too saturated.

Dual-Band Wifi FeaturesSoon after 2.4GHz was introduced, many urban areas started having issues with it. It became slower and unreliable as everyone’s devices were on it. Unfortunately, that has remained until today.

Although the 5GHz band was a tremendous single-band solution, it wasn’t extremely fast at the time. It had a shorter range, and most people had 2.4GHz-only devices at the time. The channel couldn’t survive on its own as nobody wanted a 5GHz only router.

This issue led to the co-existence of both bands in what is now known as the dual-band Wi-Fi router. You get backward compatibility and excellent performance from a single device. Everyone is happy.

What Are Tri-Band Routers?

Just as dual-band routers came into being due to a necessity, tri-band routers are doing the same. To understand this better, we’ll use a typical gigabit AC2600 dual-band router as an example.

This type of dual-band router offers network ports with a maximum speed of 1000Mbps or 1Gbps. The AC attached to 2600 refers to the 802.11ac standard, otherwise known as Wi-Fi 5. And 2600 refers to the total speeds offered by both bandwidths; 800Mbps on the 2.4GHz channel and 1733Mbps on the 5GHz channel.

Now, a Wi-Fi client or device can only connect to one of these channels at a time. This feature means that the most you can get out of our router example is 1733Mbps. But what if you have more than one Wi-Fi device? Your router will need to share the speed in half with two devices, providing each device with 866Mbps.

Now imagine if you have about 10 devices connected to your router; the best speed you’ll get is just about 170Mbps. A hundred clients reduce the speed even further as they’ll only get about 17Mbps.

In an ideal world, a home wireless router can host about 253 different devices. Imagine how slow the speeds will be if all 253 devices are connected to it.

– Tri-Band to the Rescue

In 2014, chip makers decided to make things better by creating tri-band routers that would offer two 5GHz bands and one 2.4GHz band. They also decided to split users on the 5GHz channels into two groups — the lower and upper channels.

Both channels get one 5GHz band each, allowing the total number of users on the channel to remain the same while enjoying more bandwidth.

In simple terms, a tri-band router allows you to enjoy twice the bandwidth on the 5GHz channel and one 2.4GHz band that can be used as a backup for long-range devices.

Tri-Band and Internet Speed

The speed provided by your internet service provider is not affected by your tri-band router. Your router can’t influence your ISP’s system.

That means if your ISP is providing you with slow internet, your router will only output what it gets from your ISP. While you may notice some speed differences between a 5GHz client and a 2.4GHz client, the overall speed will not exceed what your ISP is offering.

For instance, if your ISP offers a maximum speed of 300Mbps and your router can provide you with 1.3Gbps, the capped speed you’ll get will be 300Mbps since that is the top speed ISP is offering.

What Are the Differences Between Dual-Band vs Tri-Band?

The main difference between Dual-Bad and Tri-Band is, Tri-band offers three times the bandwidth, while dual-band is more affordable.

To make things understandable and more straightforward, we’ll list out the pros and cons of each router type.

– Dual-Band Pros

  • It offers more bandwidth.
  • It is the current market standard, so it’s cheaper than tri-band.
  • It offers excellent range and stability.
  • Dual-band routers are compatible with new 5GHz devices.

– Dual-Band Cons

  • 5GHz isn’t populated yet, and you’re likely to experience interference on 2.4GHz.
  • The number of connected devices affects the amount of wireless speed you get.
  • 5GHz has lower object penetration and a shorter range, especially when there are many obstacles like furniture and walls.

– Tri-Band Pros

  • It offers three times the bandwidth thanks to the three separate bands.
  • Bands can be dedicated to each device in your home or office.
  • You experience less interference since you have more bands.
  • A good multiband router also provides high CPU speeds that allow files to be transferred faster.
  • Smoother handling of wireless devices.
  • The speeds offered by tri-band wireless routers are less likely to be affected when multiple devices are connected.

– Tri-band Cons

  • They tend to be pricier than dual-band routers.

You may not notice the difference between tri-band and dual-band routers if you don’t have many devices compatible with 5GHz.

When Should I Get a Tri-Band Router?

Tri-Band Router Wifi StandardsGetting a tri-band router would be overkill if you’ll be using it in a typical home setup. If you stay in a small apartment where all you’ll be connecting are your gaming console, a laptop, and a smartphone, a dual-band router is ideal for you.

However, if your home is set up in a way that: you’re streaming 4K videos downstairs, your spouse is watching recipe videos on YouTube in the kitchen, your guests are going ham on Call of Duty, and your children’s Pandora station is always on, then you might consider getting a tri-band router.

Other Use Cases for Tri-Band Routers

As we mentioned earlier, tri-band routers shine when there are many 5GHz clients on the network. They are also an excellent investment if you’re looking to use them for one of the following:

– A Wireless Mesh Setup

A wireless mesh setup is a system where multiple wireless hardware broadcasters link to each other without the need for network cables.

Using tri-band wireless routers for this system provides you with reliability and efficiency. The tri-band system will use one of its 5GHz bands as its dedicated server, which will link each broadcaster in the system. Clients or devices will have access to the remaining two bands.

With this system in place, your home network will become reliable and efficient. You’ll have better coverage and be less susceptible to signal loss. Also, the nodes in a mesh network configure and repair themselves when there’s an error because the nodes communicate with each other, providing data on path changes.

However, it’s important to note that using network cables to link the broadcasters in your mesh setup is still the most reliable way to get a non-compromising mesh system.

With a wired system, you’ll be using dual-band broadcasters as using a tri-band system would be overkill and a waste of money.

Also, note that while some standalone routers from brands like Synology and Asus can be integrated into a mesh system, most standalone routers can’t be used in a mesh system.

There are router combos that are sold together to create a mesh system. If you want to use different routers, ensure that they can be in a mesh setup.

– Speedy Broadband Connection

Do you have a gigabit-class broadband internet connection? If yes, getting a tri-band router is one of the best things you can do for yourself.

A tri-band router will help you provide more clients on your network with high internet speed at the same time.

– Heavy Local Wireless Network Usage

Tri-band routers are ideal for those who use extensive wireless networks for their local tasks instead of wired connections. You’ll get more local bandwidth, allowing you to backup, edit, and transfer files faster.

Also, if you have virtual reality headsets you use on Wi-Fi, a dedicated 5GHz or 6GHz band will significantly enhance your experience.

– Tiers and Compatibility

Thanks to the two 5GHz bands on tri-band routers, you can dedicate one 5GHz band to offer top speeds to specific clients while the other bands serve legacy clients in compatibility mode. This feature can be helpful if there are multiple clients with different Wi-Fi standards or tiers on your network.

Wi-Fi 6E and What It Means for Tri-Band

Wi-Fi 6E is still Wi-Fi 6 but extended, which is what the ‘E’ stands for. So, instead of having two 5GHz bands and one 2.4GHz band, Wi-Fi 6E aims for one 2.4GHz band, one 5GHz band, and the new 6GHz band.

Wi-Fi 6E offers the same speed as Wi-Fi 6, and even their functions are the same. So why then do we need it?

Well, the 5GHz frequency isn’t solely made for Wi-Fi. It’s used for other applications, including radars, which are more important than Wi-Fi.

Now, when these prominent applications come to the channel, Wi-Fi users are kicked off for a short while to make the channel better and reliable for those applications, which is why when you’re close to an airport or weather radar, your 5GHz Wi-Fi band becomes unreliable.

The goal of Wi-Fi 6E is to provide the benefits of the 5GHz band through 6GHz, so users don’t experience those short interruptions.

However, there are some caveats:

  • Wi-Fi 6E offers a much shorter range and lower object penetration than Wi-Fi 6.
  • You’ll need to buy new hardware as older hardware does not support the 6GHz band.
  • The hardware is likely going to be expensive.


We’ve covered a lot of points to help you understand the dual-band vs tri-band debate. Here are some key points to keep in mind if you’re looking to buy a router:

  • Dual-band wireless routers have two bands, 2.4GHz, and 5GHz.
  • Tri-band wireless routers have three bands; one 2.4GHz and two 5GHz.
  • Dual-band uses the 802.11ac standard now known as Wi-Fi 5.
  • Tri-band uses the 802.11ax standard, now known as Wi-Fi 6.
  • Wi-Fi 6E is an extension of Wi-Fi 6, and it offers one 2.4GHz, one 5GHz, and one 6GHz band.
  • The 5GHz and 6GHz bands offer more speed but shorter range and object penetration than the 2.4GHz band.
  • The 2.4GHz band is saturated because many devices that use radio frequencies use the channel.
  • Beamforming allows you to send data to your clients reliably and efficiently.
  • Tri-band routers won’t improve the speed allotted to you by your internet service provider.

Getting a tri-band router would be overkill if you don’t have many 5GHz clients in your network. While the extra band helps and would be great to have, it’s not a must-have. If you can afford it, or you’d like to use it for some of the use cases listed above, go ahead and proceed with a tri-band wireless router. It’s always nice to turn things up.
