Design and Implementation of Battlefield Voice and Data Transmission Module Based on ZigBee

In order to achieve the close wireless transmission of voice and data in the battlefield, the paper combines voice transmission and ZigBee wireless network, and design a small wireless network to substitute of wired communication. IAR's Embedded Workbench was used as the development platform, and control module, voice module, wireless communication module, power amplifier module and data interface module were designed. RALCWI voice compression algorithm was used to ensure voice quality. Several 2.4 GHz ZigBee network nodes were developed and a 2.4 GHz ZigBee Small network was constructed. Voice and data could be free transferred in the network. The functions of voice processing and networking, wireless data transceiver, data transmission are also realized by software. The problem of wireless transmission on the battlefield is solved.
