What is the maximum data transmission speed for Bluetooth devices?

1 Mbps
3 Mbps
12 Mbps
54 Mbps

The correct answer is: 3 Mbps

The maximum data transmission speed of Bluetooth devices is 3 Mbps. This speed is associated with Bluetooth 2.0 + EDR (Enhanced Data Rate), which was a significant upgrade over previous Bluetooth versions that offered lower speeds. This enhancement allows for faster data transmission between devices, enabling better performance for applications that rely on wireless communication, such as audio streaming or file sharing. Earlier versions of Bluetooth, such as Bluetooth 1.2, were limited to speeds of up to 1 Mbps, and while newer standards, like Bluetooth 3.0 and 4.0, introduced even faster speeds, they use a different approach to achieve that, primarily leveraging Wi-Fi technology. Therefore, while the highest speeds attainable in newer Bluetooth versions may exceed 3 Mbps, the standard maximum for Bluetooth 2.0 EDR remains a critical benchmark for understanding Bluetooth capabilities.
