Walkie-Talkie is one kind of two way radio, it is widely used in people’s daily lives. Through decades of development, the products of Walkie-Talkie now is mature and diversified. With the development of short-distance wireless communication technology, a new trend of the combination of Walkie-Talkie and the new short-distance wireless communication technology is shown, such as Walkie-Talkie which used ZigBee technology. Besides, the combination of chi flat iron Walkie-Talkie with voice codec technology, and design specific function for a specific cheap ralph lauren polo shirts customer is also in exploration, and it is full of important research value and application significance.

This paper simply introduces short wireless network technology of ZigBee and G.726 protocol. Compared with other short-distance wireless communication technology, ZigBee technology has the features of lower transceiver chi hair straighteners power, lower data rate, lower cost and lower power consumption. G.726 protocol is widely used in product development industry. The G.726 protocol contains 4 speeds, such as: 16kbps, hair straighteners, 40kbps. According to the different demands of Lacoste Polo products development, we can choose the suitable speed. G.726 protocol reduces the speed of the voice, and does not destroy the original sound.Based on a well analysis of ZigBee technology standard and G.726 protocol, the paper presents a scheme of design and implementation of Walki-Talkie system terminal on Freescale MCF5213 microprocessor platform.
