Bluetooth positioning is a kind of GPS signal wireless receiver, it can receive the GPS data after processing through the Bluetooth wireless technology to send to the cell phone, PDA, computer and other devices to assist the user positioning. The emergence of Bluetooth positioning, can make ordinary digital devices also have positioning function.

Extended information:
Bluetooth technology operates in the globally available 2-4GHz ISM (Industrial, Scientific, Medical) band at a data rate of 1Mb/s. Theoretically, technology operating in the 2-45GHz ISM band could enable devices up to 30m apart to connect to each other at up to a 2Mb/s rate, but this is difficult to achieve in practice. In practice, this is difficult to achieve.
Applying the Bluetooth plonk and play' concept, which is similar to the concept of 'plug and play', any Bluetooth device can establish a connection as soon as it searches for another Bluetooth device, without the need for the user to carry out any setup, which can be explained as It can be interpreted as "connect-and-use". This makes it even more advantageous in environments where the radio environment is very noisy.
