Abstract

본 발명은 셀룰라폰에 관한 것으로 셀룰라폰의 통화시 발생되는 고주파 고전력에 의한 인체의 전자파 피해를 배제하도록 한 것이다.The present invention relates to a cellular phone is to exclude the damage of electromagnetic waves of the human body by the high frequency and high power generated during the call of the cellular phone.

본 발명은 셀룰라폰에서 고주파 고전력으로 기지국과 음성신호 및 데이타를 송수신하는 RF모듈을 분리하여 소정대역의 중간주파수를 통한 사용자 모듈과의 송수신을 사용자의 전파 피해를 배제하며 소형 및 경량의 사용자 모듈의 휴대로 사용이 간편하고 저전력의 소목 배터리의 사용시간 및 통화품위가 향상된다.The present invention separates the RF module for transmitting and receiving voice signals and data with a base station at high frequency and high power in a cellular phone, thereby eliminating radio wave damage to the user module through an intermediate frequency of a predetermined band, It is easy to carry and improves the usage time and call quality of low power joiner battery.

또한 전파의 취약지역에서 RF모듈과 사용자 모듈의 원거리 통화로 통화성공에 신뢰성을 제공한다.In addition, it provides reliability for successful call by remote communication between RF module and user module in the weak area of radio waves.
