What is the communication distance of Bluetooth?

Bluetooth has the concept of “Class.” Even with the same Bluetooth product, the strength of the radio wave differs depending on the class that is certified. That is, the communicable distance also changes.

Before you buy a Bluetooth product, make sure that you have the required class before purchasing so that it does not say, “The radio wave did not reach …”. There are three types of Classes 1-3.

Types of Bluetooth communication distance and communicable distance

One thing to keep in mind when choosing a product is that Class 1 devices do not always reach the maximum communication distance of 100m. For example, earphones with a communication distance of 20 m and microphones with a range of 50 m are also classified in Class 1. In other words, if the maximum output is “more than Class2 and within 100mW”, they are all equally classified into Class1.

As described above, even if the products are of the same class, the communication distance varies. If you want to focus on range, check the maximum output for each product.

Also, the intensity of radio waves that can be output differs depending on the country or region where the device is used. The upper limit is about 50 mW under the Japanese Radio Law, but not overseas. Besides, keep in mind that the distance may fluctuate depending on the performance of the receiving antenna and power amplifier, so it cannot be measured unconditionally.

How to set up pairing using iPhone

1. First, launch the iPhone settings screen and tap “Bluetooth.”
2. When Bluetooth is turned on, it will detect nearby devices, so tap it.
3. Tap the device, and if “Connected” is displayed, pairing is complete.

How to set up pairing using an Android smartphone

1. Launch the Settings screen and tap “Bluetooth.”
2. Turn on Bluetooth to detect nearby devices.
3. Since pairing is required, tap “OK” to complete the setting.

The setting method varies slightly depending on the terminal and OS version, but if you turn on Bluetooth, it will automatically detect nearby devices. The procedure is not complicated, so check it on your device.

Procedure to connect Bluetooth earphone with Windows PC

1. Start pairing
First, operate the buttons on the Bluetooth earphone side to start matching.

The operation method differs depending on the earphone or speaker, so check the manual.

* Playing and stopping, power and volume are nothing, but you may start pairing by pressing and holding a relevant button.

2. Add device
Open “Devices and Printers” in Control Panel, and click “Add Device.”

Many people drop out without finding this. Now, click on this to start searching for devices.

When the Bluetooth earphone is detected automatically, the device installation will begin.

Windows now recognize the Bluetooth earphone as a playback device.

3. Priority output for Bluetooth earphones
However, with this alone, you will not be able to hear the sound from the Bluetooth earphone. As before, you will get out of the speaker.

This is because the speaker you have been using has priority over Bluetooth as the output destination.

Go to “Control Panel”-> “Sound,” right-click the icon that says “Bluetooth Audio Device,” and try “Set as Default Device.”

About behavior
With this setting, the sound of the Windows PC will be played from the Bluetooth earphone, but no sound will be output from the speaker.

Here, when you turn off the Bluetooth earphone, it automatically switches to output from the speaker.

Also, when you turn on the Bluetooth earphone again, the output to the Bluetooth earphone has priority still, and the sound output from the speaker stops.
