What is the range and speed of Bluetooth?

Published in Bluetooth Technology 2 mins read

The provided reference focuses only on the speed of Bluetooth, so I'll address that part of the question. I will present the theoretical and real-world speeds according to Bluetooth version.

While the reference doesn't give the range of bluetooth I can give a summary table for both.

Bluetooth Speed and Range

Bluetooth's speed capabilities vary depending on the version. While range also varies. Here's a breakdown:

Speed

Bluetooth Version Theoretical Max Speed Real-World Speed (Typical)
Bluetooth 4.0 Up to 25 Mbps 2-3 Mbps
Bluetooth 5.0 Up to 50 Mbps Up to 24 Mbps
  • Note: Real-world speeds are often lower than theoretical maximums due to environmental factors and device limitations. The speeds provided are under optimal conditions.

Range

Bluetooth Class Power Output (mW) Range (Typical)
Class 1 100 mW Up to 100 meters (328 feet)
Class 2 2.5 mW Up to 10 meters (33 feet)
Class 3 1 mW Up to 1 meter (3.3 feet)
  • Note: Range can be significantly affected by obstructions like walls, interference from other devices, and the Bluetooth class of the transmitting and receiving devices. Modern devices typically use Class 2.
