Bluetooth remote ptt and handsfree communication system and method thereof

A remote PTT(Push To Talk) and handsfree communication system using Bluetooth and a method for providing the same are provided to execute a call through a Bluetooth wireless headset due to freely using both hands by remotely controlling the PTT function of various radios, including a TRS(Trunked Radio System) terminal, by wireless. A remote PTT and handsfree communication system using Bluetooth comprises a dongle(110), a headset(120), and a PTT key device(130). The dongle(110), connected to a radio(100) or a CDMA terminal, toggles either Tx mode or Rx mode according to a key signal from the PTT key device(130). In Rx mode, the dongle(110) transmits audio signals, outputted from the radio(100), to the headset(120). In Tx mode, the dongle(110) receives voice signals from the headset(120) and outputs them to the radio(100). The headset(120) receives audio signals from the dongle(110) and outputs them. The headset(120), if a user's voice is inputted, transmits the voice signal to the dongle(110). The PTT key device(130) transmits a key signal to toggle either Tx mode or Rx mode according to the user's operation. The dongle(110), the headset(120), and the PTT key device(130) execute short range wireless communication using Bluetooth.
