Ultra wideband communications based on chaotic signal is considered for low data rate, ranging application that is under standardization by the task group IEEE 802.15.4a. The current standard works are introduced and the proposed direct chaotic system is introduced. The PHY layer including transceiver, modem, and a ranging function are designed and implemented to realize a communication with low hardware complexity, low cost, efficient power management, robustness in multipath and flexible pulse length.
