Bluetooth is really an extraordinary invention: it frees us from all these cumbersome wires and takes our favorite music everywhere with us.
Precisely, one of the criteria to consider closely when choosing a Bluetooth speaker, a shower speaker or any Bluetooth device, in addition to the quality of the sound transmitted, is the range of the Bluetooth signal.
Indeed, what is the point of buying a Bluetooth device if the signal stops or deteriorates when you move your device a few meters away?
Bluetooth Ranges and Speeds
Bluetooth is a communication standard that allows two-way data exchange using ultra-high-frequency radio waves in a 2.4 GHz frequency band.
Bluetooth 1.0, developed in 1999, had a range of only 10 meters. The range gradually increased from Bluetooth 4.0 (60 meters) to Bluetooth 5.0 (200 meters).
The speed has also increased: from 1Mbit/s with Bluetooth 1.0 to 5Mbit/s with Bluetooth 5.0.
Currently, the most popular version of Bluetooth is 4.0, which offers a range of 60 meters and a data rate of 3Mbit/s.
What Is the Most Common Range on Bluetooth Speakers on the Market?
The quality Bluetooth speakers are equipped with at least Bluetooth 4.0. This is the case with the Doss Touch Wireless Bluetooth Speaker (4.0), the JBL Flip 4 (4.2), the TrebLab HD55 (4.1) or the Aomais Sport II (4.0).
It should be noted that speakers equipped with Bluetooth 5.0 are no more expensive than those equipped with older versions: you can easily find them from about thirty dollars.
As a reminder, with Bluetooth 5.0, you will have a range of 200 meters, compared to 60 meters for Bluetooth 4.0.
Outdoor Use Versus Indoor Use
The range of a Bluetooth device depends on many factors (antenna quality, sensitivity of the receiving device, transmitter power…).
Among these factors, there is one that plays a key role: the different obstacles that can exist between the two devices connected to each other.
Outdoors, you can achieve a range of about 100 meters or more, on open ground for example.
But inside, many obstacles will prevent the Bluetooth signal from traveling properly, which will drastically reduce the range of the devices.
This is why a range of 10 meters is often used (for Bluetooth 4.0). It is very often this distance that is indicated on the manuals of the various Bluetooth speakers. Bluetooth 5.0 can have a range of up to 30 meters.
What Range for What Use
First of all, the question to ask yourself is the type of use you will make of your Bluetooth speaker. Are you going to use it exclusively indoors, or rather to accompany you on outings, picnics, at the beach…
If your use is mainly indoors, do you just want to soundproof a room or your entire apartment?
How to Improve the Bluetooth Range
Erase Physical Barriers
As mentioned above, Bluetooth relies on two-way radio communication to work. As a result, any obstacle between the two connected devices may limit the effective range of the connection.
Thick objects between the two devices degrade signal quality, so by removing these barriers, you will improve the connection distance.
A fact as innocuous as opening a door can allow the Bluetooth signal to pass through!
Use a Repeater
You can also use a repeater, which is a device that lies between the two Bluetooth devices. This will extend the range of the device with the smallest range. For example, a Bluetooth speaker with a range of 10 meters connected to a repeater with a range of 100 meters, can itself enjoy a range of 100 meters.
Note that this solution is more suitable for enclosed spaces, such as a house or apartment, but is not suitable for outdoor use.
Beware of Interference!
Using several Bluetooth devices at the same time in an enclosed area can cause interference and thus degrade signal quality as the devices will be competing for the same bandwidth.
Reduce the number of devices used simultaneously to restore a correct signal quality.
Check the Battery
Most Bluetooth devices are completely wireless, they need their batteries to transmit their signals.
A low battery level can cause poor signal transmission.
Check the battery level regularly and make sure that it is always higher than half. If necessary, fully recharge the battery.
Don’t Forget to Update Your Equipment!
It is not only your phone that you need to update regularly. Almost all the devices we buy now are connected and must therefore be updated regularly.
This is even more true with Bluetooth devices such as speakers.
Monitor the manufacturer’s website of your speaker regularly: it probably publishes regular updates. Check that the latest update is installed.
All these tips should help you to listen to music in Bluetooth in good conditions.
