Technology has come a long way over the recent past years, where WiFi has become the central hub of any home. It has given us the privilege of not having to tackle cables and messy wires, where you can easily connect all your devices on one network and enjoy streaming or surfing the internet. Routers too have advanced in ways that most users are unaware of. Having a lot of wireless devices connected to the same network can over burden it and cause problems such as lag, buffering streams and slow web browsing. So these devices use up a lot of data and cause congestion. So manufacturers came up with a way to ease the load by having not one, but three frequency bands. This way more devices can be connected on the different bandwidths while at the same time not slowing down your internet.
Firstly, let’s talk about dual band routers. They work on two frequencies, which are 2.4GHz and 5GHz. Modern 802.11ac routers use the 5GHz spectrum since it’s less cluttered and faster. This basically means that the router is not only compatible backwards but can also host two different networks at once. Newer devices will connect to the 5GHz frequency while older devices will connect to the slower 2.4GHz. Although dual band routers are slightly more expensive than single band routers, they are worth the money especially if you have a lot of devices to connect to your network. Dual band routers are commonly sold as AC1900 products and provide a combined bandwidth of 1900Mbps; 600 from the 2.4GHz frequency and 1300 from the 5GHz. But keep in mind you will have shorter range because 5GHz waves don’t easily travel through walls.
Now talking about tri band routers, they basically work on 2.4GHz and two 5GHz bands. More bands essentially means less interference since data has more frequencies to travel on. These frequencies provider a faster connection and a sum total of almost 4000Mbps. These routers are mainly sold as AC3200 and AC3500, with the same 600Mbps on the 2.4GHz and 1300Mbps on 5GHz but with an additional 1300Mbps on the third band. Tri band routers automatically assort devices into different networks so there’s more bandwidth to share and each device has good speed as well. However, tri band routers are more expensive than single and dual band routers. Also, tri bands with 60GHz have shorter range than both single and dual band routers.
At the end, a user’s needs specify the type of router they need. Since there are more modern devices being released on a daily basis, manufacturers are moving towards dual band routers which essentially support two frequencies, a lot more bandwidth and improve the overall performance of your network. Tech savvy users can opt for the tri band routers who want higher bandwidth. Even though single band routers are cheap and common, they don’t support some of the latest wireless devices.
