What is a Dual Band Router?

Have you seen a label on the router retail package as ‘Dual Band Router’ or ‘Dual Band Smart Wi-Fi Router’ or something similar?

Would you like to know what it is? Then you are at the right place. To begin with, I would like to tell you few basic things related to network connectivity of the routers.

There are in total of 3 network standards. One is 802.11g, 802.11n, and 802.11ac. The very new standard today is 802.11ac which is fast when compared to other standards. The conventional routers do come with 802.11n and 802.11ac standards but to get the improved speed, you need to have the latest technology router with AC standard.

What is Dual Band Router then?

Let me explain it in brief.

Dual band means the router with two different frequencies (or bands). The regular routers will only operate at certain frequency say like 2.4GHz leaving other bands.

What would be the problem then?

There is an issue. Most of the Smartphones, Tablets, Laptops do connect to the network at the 2.4GHz band. If the higher number of devices connects to the same network at the same period, that makes the problem. Even, some of the electronic devices do operate at the same frequency levels which creates interference to the broadcasted network. Therefore, the performance of the signal becomes weak which in turn affects the connectivity. Assume, how the bandwidth affects when you live in an apartment? Hope you got me!

So, to avoid these connectivity problems, router manufacturers like Netgear Router etc., induced another band of frequency called 5GHz. Most of the other devices except routers won’t operate at this frequency. Therefore, it is possible to reduce the network interference.

Let me explain you with an example. I have a Smart TV, Laptop, a Smartphone, Micro Oven, Refrigerator in my home. All are very nearer to each other. When I connect my Smart TV, Smartphone, and Laptop to the router at 2.4GHz, I may face lower connectivity issue that returns in buffering of TV programs. Since the signal transmits over the air, the devices which are attracted to the same frequency band may create interference resulted in decreased bandwidth.

To avoid this problem, I will connect my TV to 5GHz frequency and other low priority devices to 2.4GHz band. That will solve the issue.

If you really want to optimize your Internet speed then do consider of getting good dual band router. It not only improves the speeds but it also gives you freedom to choose between two frequencies. But, the uplink and downlink speed depends on the ISP provider. Don’t expect 2x fast by just upgrading to dual-band router.
