Bluetooth Wireless Networking
The class 2 devices are lower power, offering up to 2.5 mW of power. A regular antenna will give them a range of around 50 - 100 feet. Class 3 devices use even less power, up to 1 mW of power to be exact. With a regular antenna, they will have a range of around 16 - 33 feet.
Even though you may not realize it, Bluetooth wireless technology has never been intended for anything other than short distance types of communication. With Bluetooth wireless, the short range is actually a benefit.
For one, the short range will reduce the change of interference between your devices and those that belong to others who are nearby. Overall, this is a basic type of security, designed to protect you and your devices.
