PURPOSE: A synchronization device of a DECT(Digital Enhanced Codeless Telephone or Digital European Codeless Telephone) using Bluetooth is provided, which prevents a signal attenuation and delay generated on a wire by transmitting a synchronous signal wirelessly, and reduces human power required in the installation and maintenance. CONSTITUTION: The first DECT(Digital Enhanced Codeless Telephone) system(202) generates a synchronous signal and then outputs it, and the first Bluetooth module(204) receives the synchronous signal being output from the first DECT system and then transmits it to a wireless section. The second Bluetooth module(206) receives the synchronous signal transmitted from the first Bluetooth module. And the second DECT system(208) receives the synchronous signal received through the second Bluetooth module, and is operated by being synchronized to the first DECT system. A data transmission/receiving range of the first or the second Bluetooth module is extended using an RF repeater and amplifier(210).
