Bluetooth Range
Most Bluetooth devices are described as 'Class 2'. These are very low power (typically 1 milliwatt - 1/1000th of a watt) and have a range of about 10 m (33 ft).
Some devices - for example, some plug in 'dongles' that can be added to to laptop computers - are Class 1. These have range comparable to that of Wi-Fi, ie, 100 m or 330 ft.
With Bluetooth, short range is actually a benefit, because it reduces the chance of interference between your Bluetooth devices and those belonging to other people nearby.
Devices that Use Bluetooth
A limited, but growing number of devices use Bluetooth at present. Devices that are starting to have Bluetooth connectivity built in include:
• Digital cameras and camcorders
• Printers
• Scanners
• Cell Phones
• PDAs
• Laptops
• Keyboards and Mice
• Headsets
• In-car handsfree kits
• GPS navigation receivers
• Home appliances (microwaves, washers, driers, refrigerators)
In addition, add on Bluetooth adapters are available for computers (eg with a USB interface) and for PDAs (eg SD cards).
