Would you like to connect your smartphone to another device via Bluetooth, but the connection cannot be established? The range may not be sufficient. In this article we are going to show you what you should know about the Bluetooth range of your cell phone and how to get maximum range.
What is my range?
Bluetooth is a popular method for transferring data over short distances. For example, if you want to transfer photos from one smartphone to the other or if you want to play a music playlist on your Bluetotth headphones or speakers. Compared to a WLAN connection, the wireless connection via Bluetooth is more energy-efficient , but usually also slower . The range of a Bluetooth device can be divided into three classes.
| class 1 | up to 100m |
| 2nd grade | up to 10m |
| Class 3 | up to 1m |
| Klasse 1 | bis 100m |
| Klasse 2 | bis 10m |
| Klasse 3 | bis 1m |
Most cell phones use class 3 , as this not only saves electricity, but also ensures that not too many smartphones interfere with each other when connecting to other devices. With Bluetooth headphones is mostly Class 2 used so that a range of up to 10m can be guaranteed. In addition to the differentiation into the classes listed above, new versions of the Bluetooth standard are published on a regular basis. Smartphones, such as the Samsung Galaxy S8 / S9 or the iPhone 8 and X, are already equipped with Bluetooth version 5. However, thanks to the downward compatibility, you can also connect devices that use older Bluetooth versions. The latest version, Bluetooth 5.2 with an improved transmission speed, was released in January 2020. You can find information about which Bluetooth version your smartphone is using on the website of your mobile phone manufacturer in the data sheet for your smartphone ..
Generate maximum range
In order to achieve maximum range, you should make sure that the devices are as close together as possible . Obstacles such as walls reduce the range of your smartphone. Another possibility is the so-called Bluetooth repeaters , however, similar to the WLAN repeaters , these are only available for purchase in electrical retailers and are only worthwhile for devices from class 2 . Hold the devices to be connected in different positions to each other and make sure to have them at least within sight to create a successful connection.
