Described herein are techniques for self-synchronization of wireless nodes. For example, the technique may involve determining a repetition rate for receiving a signal from another access point, wherein the repetition rate identifies the another access point. The technique may also involve receiving at the access point an unmodulated impulse radio (IR) ultra wide band (UWB) pulse train from the another access point during a transmission interval associated with the repetition rate. The technique may also involve synchronizing a first clock associated with the access point to a clock associated with the another access point based on the received unmodulated IR UWB pulse train.
