Connecting to the Internet through mobile phones or tablets is very common and we do it through wireless networks. However, we do not always have an adequate speed and we can suffer from limitations and problems. In this article we are going to talk about a very important factor to be able to achieve a better connection: having dual band Wi-Fi on your mobile and tablet. We will explain what it is and why it is important.
How dual-band Wi-Fi works
To connect to a Wi-Fi network, we can generally use both the 2.4 GHz and 5 GHz bands. Modern routers have this option, as well as repeaters and the devices we use to navigate. Normally we will find two wireless networks to which we can connect and each of them works on a different frequency.
Not all devices are compatible with both bands, but most current ones are. In the event that a device is not dual band, it can only be connected to the 2.4 GHz band. This will cause it to be limited and unable to reach maximum speed, in addition to other connection problems.
The fact of having both bands available allows us to choose at all times which one is best for us to connect to. It does not mean that one is better than the other, since both have their advantages and disadvantages. In general, we can say that the 2.4 GHz band is the one with the greatest range, but the speed is more limited. In contrast, the 5 GHz band offers more speed, but is more sensitive to distance and possible obstacles. You can see if the mobile is dual band.
Because it is important
So why is it important for a mobile or tablet to be dual band? The first thing is to be able to achieve the maximum possible speed . Connecting the mobile to the 5 GH band, in optimal circumstances, will cause us to have a much higher upload and download speed than we would have in the 2.4 GHz band.
But it is also very interesting in order to avoid interference . There are more devices connected to the 2.4 GHz frequency. For example, Bluetooth devices or a microwave. On the other hand, the 5 GHz band has fewer interference problems and we will achieve better connectivity.
In addition, another factor to take into account is that the 5 GHz band has many more channels available and they are not interposed. This means that we will have fewer problems of finding ourselves before a saturated Wi-Fi channel in case our neighbors connect to the same one as us or to a nearby one. Very useful if you live in a building where many networks are available. You can always see which Wi-Fi channels your neighbors are using.
On the other hand, being able to choose between the two bands will allow you to connect from further away . If you use the 2.4 GHz band you will get better coverage when you have to connect from a greater distance or when there are many obstacles. If you only connect to the 5 GHz, you will be more limited in this regard.
In short, as you have seen, it is important today to have a dual-band mobile or tablet. This will allow you to have faster Internet speed, less interference and problems when connecting wirelessly.
