Abstract:
1. A mobile communication device for wirelessly transferring information to and from a base unit, comprising: (a) an RFID module to receive a wake-up communication from the base unit and send connection parameters back to the base unit; (b) a wireless communication module which is responsive to the connection parameters received from the base unit, and remains in a shutdown state with only a clock running until the RFID module receives the wake-up communication from the base unit and enables a microcontroller to wake-up the wireless communication module; (c) wherein the microcontroller is coupled between the RFID module and the wireless communication module to wake up the wireless communication module when the RFID module receives the wake-up communication from the base unit; and (d) wherein the connection parameters have an address of the wireless communication module transmitted by the RFID module to enable an inquiry period to be bypassed when the base unit connects to the wireless communication module.
