Five myths about Bluetooth that were not true

How to share installed applications easily and via Bluetooth

When some new technology or development arrives on the market, it always does so surrounded by all kinds of myths, about its possible dangers. This is something that happens regularly, also with a technology that has been among us for many years. like Bluetooth. We have seen the evolution it has had over the years, in addition to the importance it has had and continues to have in the field of smartphones.

Over the years there have been many rumors and myths about Bluetooth. Most likely, you've heard some of them on occasion. Here we talk about five myths about it, which today we can say were not true. Dismantling myths.

Using Bluetooth consumes a lot of battery

For a long time, Bluetooth has been associated with excessive power consumption in the phone. This is not something too far-fetched, since in its beginnings it was not completely perfected and yes there was a greater than expected or desired energy consumption, which made the phone's battery last less than it should. Later versions have been improving this.

Especially since the launch of Bluetooth 4.0 officially we have been able to see important changes. It was in this version when the so-called Low Energy (LE) module was introduced, aimed at lower energy consumption. This allows that when we use this technology, they are going to look for connected devices, as until now, only consuming less. Since until there is no data transfer, this consumption is reduced.

Thanks to this module, consumption has been reduced by half. So it is an improvement of great importance, which we noticed in the use of Bluetooth on an Android phone. It is something that is still working, as far as possible. But this myth has been dismantled thanks to the work that has been done to improve this.

It's bad for your health

This is an argument that we have surely heard on occasion. Especially when Bluetooth arrived on the market there was a lot of talk about possible health risks. Currently, several studies have been carried out worldwide. None of them have been able to find evidence that it is something that puts our health at risk.

There were also doubts with the use of Bluetooth headphones, for fear of the possible radiation they emit. In this case the same thing happens, they are safer for health than using a smartphone, in fact. The radiation emitted by headphones is much less, which means that they are less dangerous for the health of any person. Most likely, this is an issue that will continue to be investigated, in order to demonstrate that there are no risks to people.

Bluetooth only works in small spaces

One of the most classic myths, is that Bluetooth only works at a very short distance, which forced the phones to be close to each other when transferring files with it. Of course, it works over short distances and small spaces, but we must not forget that there are several levels of it. This is a detail that we usually forget.

In class 3, the lowest, the range is less than 10 meters. Then we have the second class, which reaches 10 meters or more (around 10 meters). While the Bluetooth Class 1 call, It has a range of more than 100 meters. So it depends on the class that is used on the device, the range varies clearly.

In the case of a smartphone, the most normal is that they use class 2 or 3, which give us a range of about 10 meters. In general it is something that works well, especially since most are going to use them in confined spaces, such as your home or office. Devices that use class 1 are wireless speakers, which usually have a range of 100 meters in many cases.

Bluetooth is not safe

Another issue that has been mentioned many times is that Bluetooth is not safe. It is not the safest or best-protected technology in the world, but there has been a great job in this regard over the years. Thanks to this work they have managed to cover many of the holes or problems that were in it.

In addition, one of the biggest security problems facing Bluetooth are the weak passwords that users create. Unfortunately, it is still very common for passwords such as 0000 or 1234 to be used on the device. This is very easy to guess or hack, which makes a person can connect to that device, your phone in this case, without too many problems, with the risk that entails.

Therefore, one of the first actions that is requested to carry out on a smartphone is to change the Bluetooth password. Use a secure or a four-digit PIN that is secure and is not the typical key that is so used and so easy to guess. This is already a significant improvement in security for users.

It interferes with the WiFi

Bluetooth and WiFi are the two wireless technologies most important in recent years. You have probably heard on some occasion that someone says that if they are both at the same time, they interfere with each other. Especially if we consider that Bluetooth makes use of the 2.4 GHz frequency to operate. This leads us to think that there could be problems in this regard.

Keep in mind that Bluetooth makes use of a technology called adaptive frequency hopping, which we can translate as an adaptive frequency jump. The 2.4 Ghz band ranges from 2,400 MHz to 2,483.5 Mhz. What is done, especially since version 5.0, is that the two channels are used, each representing 50 of the band. The signal jumps from one to another frequently, allowing it to not interfere with other devices that use the band.

So this prevents that have this kind of problems with the WiFi. There will be no interference in this case, again thanks to the improvements that have been introduced over the years to avoid operating problems in it.
