What is the maximum communication range of the Bluetooth connection? (2024)

FAQs

What is the maximum communication range of the Bluetooth connection? ›

Commercial Bluetooth

Class 1 transmitting at 100 mW with a range of 100 meters or 328 feet. Class 2 transmiting at 2.5 mW with a range of 10 meters or 33 feet (most Bluetooth headsets and headphones are common Class 2 devices).

With the new Bluetooth long-range mode, you can now achieve ranges of over 1 kilometer using BLE! This is useful for extending the range of a Bluetooth connection or discovering advertisem*nts, but it also helps achieve more robust communication in noisy RF environments and areas with many obstacles.

Think of transmit power like the volume of your voice. The louder you speak, the farther away someone can hear you but the more energy it takes. Bluetooth® technology supports transmit powers from -20 dBm (0.01 mW) to +20 dBm (100 mW).

How Many Bluetooth Connections at Once is Possible? Bluetooth 5 is the latest version of Bluetooth to date and was released back in July of 2016. Through Bluetooth 5, a single primary Bluetooth connection can connect up to seven different Bluetooth devices simultaneously.

The minimum range of Bluetooth is approximately 1 meter (3 feet), and the maximum range is approximately 100 meters (328 feet). However, the range of Bluetooth depends on its class. There are three main classes of Bluetooth: -Class 1: transmits at 100 mW with a range of 100 meters.

Longer range: Bluetooth 4.2 can hold connection to another device for a maximum of 60 meters (200 feet). With Bluetooth 5.0, that distance is quadrupled to 240 meters (800 feet).

Using a Bluetooth® connection, you can use third-party devices such as wireless keyboards, headphones, speakers, car kits, game controllers, and more with iPhone. Note: iPhone must be within about 33 feet (10 meters) of the Bluetooth device.

Despite their weakness, Bluetooth signals don't require line of sight between devices. The radio waves will travel through walls easily, and their low power helps to reduce the chance of interference from other technologies that use radio waves, such as baby monitors and garage door openers.

Fortunately, there are several ways to increase the range of Bluetooth, including keeping your devices up to date, reducing interference, using an external Bluetooth antenna, using a Bluetooth range extender, using a Bluetooth amplifier, and keeping your devices cool.

Will Bluetooth work through walls? ›

The answer is yes, but with caveats. The type of wall, the strength of the signal, interference from other devices, and the distance between the connected devices all play a role in determining how well a Bluetooth signal can penetrate walls.

So, according to this comparison table between different Bluetooth versions (taken from this handy article) - The range of Bluetooth version 5 (and definitely 5.3) is 240m/800ft.
