Through adopting code-division multiple access and power control technique, receiver sensitivity of CDMA mobile phone is higher but emission power is lower – network emission power of CDMA is only 200 milliwatt, ordinary call power can be controlled can be within nought point milliwatt and its radioactive function is negligible, combining call with health! Reduction of base station and mobile phone emission power also greatly prolongs call duration of mobile phone, which means that lifetime of both battery and mobile phone increases, playing a protective role to environment and human body, so it is called “green” mobile phone.
