What’s is Bluetooth’s operating range?

Does anyone know how far the operating range of bluetooth is supposed to be?

A Look at the Basics of Bluetooth Wireless Technology

Range is application specific and although a minimum range is mandated by the Core Specification, there is not a limit and manufacturers can tune their implementation to support the use case they are enabling.
Range may vary depending on class of radio used in an implementation:
Class 3 radios – have a range of up to 1 meter or 3 feet
Class 2 radios – most commonly found in mobile devices – have a range of 10 meters or 33 feet
Class 1 radios – used primarily in industrial use cases – have a range of 100 meters or 300 feet"

There are 3 different classes of Bluetooth devices, and there is a big difference between them as far as range is concerned. Class 1 has the longest range; up to 100 meters. Class 2 has a range of about 10 meters, and the lowest power bluetooth, Class 3, is limited to less than 10 meters.
