Tri-Band vs. Dual-Band Router (What’s the Difference?)

A router is a critical networking gadget that transmits and receives data packets from your internet access point like a modem to all connected devices, including your computers, smartphones, smart TVs, and tablets.

Your internet connection largely depends on this device. Essentially, your home or office network is incomplete if you don’t have a router. Besides, it is the first line of your network’s security as it monitors and directs incoming and outgoing traffic. 

Routers transmit and receive data using different frequency bands, either 2.4 GHz or 5 GHz. They broadcast data packets over a network, either one at a time or simultaneously, depending on the selected channel or frequency band and the router’s capabilities.

So, when shopping for a router, you can choose between a single-band, dual-band, tri-band, and quad-band router. 

For purposes of this post, we shall compare tri-band vs. dual-band routers only. Keep reading to learn more about these different types of routers and how they work.

Tri-Band vs. Dual-Band Router

What is a Dual-Band Router?

A dual-band router is one capable of transmitting and receiving data packets, either one at a time or simultaneously, using 2.4 GHz and 5 GHz frequency bands. They broadcast two wireless signals to your devices, hence the name.

Dual-Band Router

Frequency bands are radio waves that transmit data over a wireless network from one device to another. They are two types of frequency bands, including 2.4 GHz and 5 GHz. The 2.4 GHz band is slow but has an extended range, while the 5 GHz is fast and offers additional network bandwidth but has a shorter range.

2.4 GHz and 5 GHz

As the name suggests, dual-band routers support the two different frequency bands for maximum flexibility and stability. You can use your router with any compatible device regardless of whether it uses the 2.4 GHz or the 5 GHz band.

Dual-band routers come in two forms: selectable and simultaneous. 

The selectable dual-band router allows you to select your preferred frequency band depending on the capability of your devices. With a selectable dual-band router, you can only choose one frequency at a time.

Simultaneous dual-band routers transmit and receive data packets using both 2.4 GHz and 5 GHz frequencies at the same time. You do not have to choose a particular frequency as the router provides two separate networks for enhanced flexibility.

What is a Tri-Band Router?

A tri-band router can broadcast three separate wireless signals so your devices can connect to the network and access the internet. The device transmits and receives data packets using one 2.4 GHz band and two separate 5 GHz bands.

Tri-Band Router

By supporting three frequencies bands, tri-band routers provide three separate networks for your devices to connect to, solving overcrowding and interference issues and guaranteeing optimum speeds and performance.

A tri-band router offers three networks in one, meaning the different bands share one SSID (network name), making it easy to manage your wireless network. 

The three frequency bands available also make it easy to connect multiple devices at once without congesting your connection. You can connect your phones, laptops, gaming consoles, tablets, and smart TVs without interfering or cluttering the network.

Besides, a tri-band router has intelligent features that automatically select the optimum frequency band for various devices. For instance, if your smartphone works best under the 5 GHz band, the router will connect the device to this particular network. If you have two devices using the 5 GHz band, the router will place them onto the separate 5 GHz networks.
