How Do Dual Band Routers Work?

Any home that wants to have wireless internet – and that?s most homes these days – is going to need to have a wireless router. The router is one of the most important parts of the whole system if you are hoping to get online, and if you want to connect devices wirelessly then a wireless router is clearly essential. In essence, the router connects the devices in your home that are able to be connected to the internet, to the modem, which in turn connects to the internet. There are many kinds of router that you might consider when you are on the market for one. In this article, we will look more closely at dual band routers, and how they work – as well as what you might need one for.

Wireless Frequencies: What Are They?

To understand and get to grips with what dual band routers are, you first need to be clear on what wireless frequencies are. When a router connects wirelessly to a device, it does so through the use of radio waves, which carry the data from the router to the device and back again. To do this, it can use a certain number of frequencies, and there are two main ones that home routers tend to use.

The frequency of a wave depends on how tightly information within it is packed, as well as how fast it is all moving. Wifi operates on one of two wave bands – either 2.4GHz or 5GHz. The latter, in truth, has only been in ordinary commercial use for a few years now. But it is going to become more and more popular in the years to come, and a big part of that will be the introduction and further usage of dual band routers.

What Is A Dual Band Router?

So in essence, a dual band router is simply the name for a router that utilizes both the 2.4GHz and the 5GHz band waves. Your dual band router is able to encode and decode data travelling along either of these waves, making it much more of a superior machine than many of the older models of router. That being said, this is a function and feature that the vast majority of modern routers will have. In fact, it is highly likely that you can expect your current home router to be a dual band router. Still, it?s good to know about it. So, how does a dual band router actually work?

How Does It Work?

Given that a dual band router is able to make use of both frequencies, you should be able to see just why it is that this kind of router is useful to have. After all, each of the frequencies have their own benefits and drawbacks, and it?s easy enough to understand what the trade-off is there. With a 2.4GHz frequency, you have more range, but a weaker signal, whereas with 5GHz you have a stronger and faster signal that can?t travel to every corner of a large home. If you live in a small home, and you are merely looking for the fastest internet possible, 5GHz would be the way to go. If you need to reach many devices around a larger home, then utilizing 2.4GHz is much more likely what you will want to do – but just make sure that you are placing high-bandwidth devices as close to the router as possible.

The Benefits Of Using A Dual Band Router

Before you make sure whether or not you have a dual band router, or if you want to have one or not, it?s useful to know about the kinds of benefits you can expect to get from using this kind of router. There are actually many of these, and it is soon going to become clear just why dual band routers really are the norm across the board these days.

One of the main advantages of using a dual band router is that you have maximum flexibility when you are setting up a home network. That?s because this kind of router uses separate wireless interfaces for each band, and in so doing ensures that you are going to be able to have the appropriate band used in each instance for each device.

There is also a common issue in the home of interference with the wifi signal, as there are a number of home devices which function on the 2.4GHz signal too. For instance, most microwaves are likely to interrupt this. Therefore, having a router that automatically deals in both 2.4GHz and 5GHz means that you will still be receiving the kind of internet connection you really want. All in all, that means a faster and more reliable internet speed at all times, which is something that everyone can get behind in their home.

There is also the very useful fact that most modern dual band routers incorporate what is known as Multiple-In Multiple-Out radio configurations, providing a much higher performance for your home network and ensuring a better connection at all times.

It?s All About The Bandwidth

But the main reason that you will want to think about making use of a dual band router is so that you have much more bandwidth to work with. The bandwidth is essentially the capacity that your internet connection has – if lots of devices are connected at once, it will be under strain, and will provide less of a flow of data to each device individually. If you are using a dual band router, however, the bandwidth capability is going to be much greater, ensuring that your devices will receive an even flow of the internet connection each.

As you can see, there are plenty of great reasons to use a dual band router, and chances are – you are already using one. But understanding why it is so important can help you in making future decisions if you need to buy a new router, and it?s good to know the options you have.
