The Bluetooth technology was designed to make wireless connections over short distances between portable devices. The class implemented in our devices by manufacturers has a maximum range of 10-15 meters with no obstacles in between.
From an article published at ehow.com we can consider the following points to improve our Bluetooth connection:
- Minimize as many large obstacles as possible between the Bluetooth-connected devices. Range improves if, for example, there are fewer walls between the devices. Range also is affected by large furniture between devices, so move the electronics or rearrange furniture to improve performance.
- Turn off or move away from competing wireless signals, such as Wi-Fi connections. Wi-Fi works like Bluetooth, but is much stronger. The signals can disrupt Bluetooth connections, shortening the Bluetooth's range.
