If you have ever utilized a Bluetooth audio receiver in order to convert a speaker into a Bluetooth speaker, you may have experienced dropouts when streaming audio. These dropouts are caused by the wireless signal not reaching the speaker. However, dropouts could also originate from other devices interfering with the transmission. In this article, I’m going to offer some tips for improving the wireless range when using Bluetooth audio receivers.
When purchasing a Bluetooth receiver you will typically find a specification for the wireless range. Most commonly available devices will operate up to 30 feet line of sight. This means that you can walk away up to 30 feet from the Bluetooth receiver and still get a clear signal. However, this range is often optimistic and does not consider the fact that anybody walking between the streaming device and the Bluetooth receiver can interrupt the signal and therefore decrease the effective range.
Also, when streaming through walls, you will often experience a drastic reduction in the effective operating range. This is due to the fact that the signal gets weaker when it travels through wall or obstacle. In order to improve the range, you can use a better antenna. This antenna can be attached to the Bluetooth receiver if it has an external antenna connector. If you don’t have a receiver that comes with an external connector, you can try to improve the location of the streaming device in order to maximize the range. I would recommend to locate the streaming device at least 6 feet from the ground. Also, make sure that there’s nothing blocking the line of sight between the streaming device and the receiver.
Also, I recommend not to locate any metal cases or other metal objects near either the receiver or streaming device. The orientation of the streaming device also can have a great impact. The wireless signal is usually polarized either vertically or horizontally. That means that reception will actually change drastically depending on how the streaming device is rotated. In order to figure out the best orientation of the device, just walk away to the maximum range where the signal starts cutting out and then experiment with the orientation of the device. Just rotated sideways and upwards and see which have a position yields the best reception. At the same time, I also recommend to raise and lower the device to see if elevation will impact performance.
