Abstract :
The Z-Phone project goal is to develop a low cost, ultra low-power, long range, ergonomic wireless headset using ZigBee Technology to transmit voice in full-duplex mode for use with leading PC VoIP programs, gaining significant communication autonomy and distance compared with Bluetooth, while DECT and WiFi consume much more power and cannot be integrated into small devices. This paper presents in a methodological way the details and performance of a voice codec implementation for Voice-over-ZigBee technology.
