Document Type and Number:
WIPO Patent Application WO/2013/051742
Kind Code:
A1
Abstract:
The present invention relates to a wireless transmitting and receiving apparatus, and to a method for transmitting and receiving using same. The wireless transmitting and receiving apparatus of the present invention includes: a transmitting device for generating an initial registration code when power is turned on, searching for a frequency using frequency-hopping through RF communication, transmitting the initial registration code to a receiving device, randomly generating a registration code matched with an input through an adjustment button, transmitting the registration code to the receiving device, and transmitting digital audio data modulated in a GFSK scheme to the receiving device; and the receiving device for maintaining a waiting mode according to the reception of the initial registration code from the transmitting device, receiving the registration code and setting audio communication to "Enable", receiving digital audio data modulated in the GFSK scheme from the transmitting device and converting the digital audio data into an analog audio signal demodulated in the GFSK scheme, and outputting the analog audio signal through a speaker. The simple transmitting and receiving device enables instructions to be transferred through each channel to indoor members from the outside. In addition, when the power is turned on in the receiving device and the transmitting device, the instructions can be transferred through a channel setting for audio data.
