Applications to improve coverage with Wi-Fi heat maps

Wi-Fi heat maps will allow us to know in detail the coverage that our Wi-Fi router or access point provides to the different locations of our home or office. There are tools that will greatly facilitate the task of knowing where the Wi-Fi coverage is weakest, and, therefore, where we must improve it to have a very good wireless speed and not have cuts due to low coverage. Today at RedesZone we are going to recommend a series of tools for both Windows and Android and iOS.

What is a Wi-Fi heatmap?

A Wi-Fi heat map is a graph that represents the strength of the Wi-Fi network signal, depending on where you are. Regardless of where you are, whether in a small or large house, a building or an apartment complex, it is a great support to have adequate Wi-Fi coverage. According to the strength of the signal, the graph is colored in different colors. For example, if the coverage is optimal, it will paint the involved area green, however, if the coverage is very poor, it will paint the area red.

Heat maps give us a summary of the characteristics of our network, as well as the people who are connected to it. Regardless of whether your role consists of being a Wi-Fi network administrator in a company, or simply managing your home network, it is a great support tool , especially when it comes to troubleshooting frequent problems such as low signal level in certain situations. parts of the area. Of course, Wi-Fi heatmaps help to prevent potential connectivity problems before setting up the actual wireless network, so it is ideal to use them before starting to deploy the different Wi-Fi access points.

Although mapping the network coverage area may take some time, it is important to do it before deploying the wireless network. Skipping this activity can result in high unnecessary costs later. Logically we will always be able to count on adding one more AP to the wireless network, but it would not necessarily solve the problem of “dead zones” or those areas with a weak signal. You can also opt for the typical Wi-Fi repeaters to extend the emitted signal, although this could further degrade the speed of the signal, considering that, at a greater distance, there will be a lower level and quality of the signal.

There are also external interferences that generally involve certain devices and parts of the structure of the place where we are. Nor should we forget electrical/radio interference and those that are typical of the environment, since they influence the quality of the signal emitted by the Wi-Fi network. For this reason, the use of this type of heat map applications is essential to determine where there is an area of ​​low coverage, and take an effective solution.

How to avoid Wi-Fi dead zones

We have seen what a heat map is and different programs that we can use. In this way we will know in which areas of the house we have the best connection and where it will be very difficult to connect. Now we are going to give some tips to avoid Wi-Fi dead zones, which are basically the places where we are not going to have access.

Place the router correctly

The first thing to keep in mind is to place the router well . This is going to be very important for the coverage to work properly. Ideally, put it in a central location in the house. We must avoid places near walls or walls, as well as areas where we are not really going to connect.

This will help avoid dead zones. It is important that the signal is distributed well and that it also points directly to where we are going to connect other equipment. Therefore, whenever possible we should think carefully about where to place the router.

Use Wi-Fi amplifiers

We can also use other devices to achieve a better wireless connection . Here we can mention Wi-Fi repeaters, Mesh systems or PLC devices. In all these cases, we will be able to extend the coverage and thus reduce the possibility that we will have errors when connecting.

Likewise, as in the case of the router, we have to place the devices correctly. The objective once again will be to achieve optimal coverage and not have problems.

Optimize device

Have we optimized the device we use to connect? This is also important to reduce dead zones and avoid Wi-Fi issues. We can always use a more powerful wireless network card, a higher capacity antenna, etc. This will help us make the connection work better.

But it is also important that the settings are correct. We must avoid using the wrong Wi-Fi band, for example. The 5 GHz band is going to be the one that offers the maximum speed, but it is more sensitive to distance and therefore more dead zones can be generated.

In short, these are some issues to consider in order to reduce dead zones when using Wi-Fi. We must ensure that the quality of the signal is adequate and be able to connect more devices without problems.
