Long Wave Induction Spread Spectrum Handheld Radio adopts technologies of Spread Spectrum Digital Signal Processing, Error Correction of Coding, Vocoder, and Digital Modulation. It is a kind of new-type induction communication equipment through the induction of mental medium (such as electric power line) to perform voice communication, it is composed of a transceiver, an antenna, and a charger. The rechargeable lithium-ion battery is internally installed in it. The product can be hand-held or used with external handset. It has the advantages of small in size, light in weight, convenient to carry, and low background noise. It can capture the signal which is lower than interference signal in the environments with strong electromagnetic interference, thus to solve the communication problem in the skip zone. This product is applicable to be used in complex environment such as railways, mines, saps, power station and so on.
