What is a Class 1 Bluetooth device?
Bluetooth has three different defined ranges, based on their output power ratings. Class 1 devices are the most powerful. These can have up to 100 mW of power, and a regular antenna will give them a range of about 40 m – 100 m (130 – 330 ft). Class 2 devices are lower power, with up to 2.5 mW of power.
What power range is Bluetooth?
Bluetooth® technology supports transmit powers from -20 dBm (0.01 mW) to +20 dBm (100 mW).
Which Bluetooth class has got better range?
Class 1 devices use up to 100 milliwatts and have a range of about 300 feet (100 meters); Class 2 devices use far less at 2.5 milliwatts and have a range of about 30 feet (10 meters); Class 3 devices are the least powerful and are “not very common” with only about a 3-foot (1 meter) range.
What does Bluetooth class mean?
Bluetooth classes define a Bluetooth device’s maximum power output; the higher a device’s output power, the longer the maximum range. The below table outlines the average power output and range of the four Bluetooth classes: Class.
What are different classes in Bluetooth?
What is Bluetooth Class?
| BT Class | >Maximum Power | Operating Range |
|---|---|---|
| Class 1 | 100 mW (20 dBm) | 100 meters |
| Class 2 | 2.5 mW (4 dBm) | 10 meters |
| Class 3 | 1 mW (0 dBm) | 1 meter |
What is the maximum distance of a Class 2 Bluetooth device?
approximately 30 feet
A power-class 2 Bluetooth® wireless device has a transmission operating range of approximately 30 feet (10 meters) within a line of sight but will vary depending on the surrounding conditions.
How do I know what Bluetooth class I have?
Most phones use Class 2 Bluetooth devices. If you know the exact device name / model we can find the class of device by looking up the bluetooth qualification details – it will list the chip in use and its device class.
What is the operating range of Class 1 Bluetooth devices?
What is the intended range for a Class 1 Bluetooth transceiver?
Class 1 devices transmit at 100 mW with a range of 100 meters or 328 feet.
Can you increase Bluetooth range?
Bluetooth has its limits. Bluetooth range extenders will help you go further than the standard connection range. The extender, also known as booster or repeater, allows you to connect devices up 150 feet apart outdoors. When indoors, the extender allows you to increase the distance by up to 70 feet.
What is the range of Bluetooth Class 1?
The class of the Bluetooth device will determine the wireless range of the device. Most Bluetooth devices are Class 2 meaning they operate at a distance of up to 30 feet. Class 1 devices can operate at a distance of up to 300 feet.
