Claim 7:
8. A method of operating an ultra-wideband communication node, comprising:
transmitting, by processing circuitry of the ultra-wideband (“UWB”) communication node, over a first communication channel, using ultra-wideband communication circuitry comprised in the communication node, one or more ultra-wideband frames to an external UWB anchor device;
determining, by the processing circuitry of the ultra-wideband communication node, scrambled timestamp sequences for said ultra-wideband frames;
determining, by said processing circuitry, designated time slots of said ultra-wideband frames, within which said scrambled timestamp sequences are to be received by said external UWB anchor device;
transmitting, by said processing circuitry using the ultra-wideband circuitry, the scrambled timestamp sequences to the external UWB anchor device in the designated time slots of said ultra-wideband frames; and
transmitting, to the external UWB anchor device, data that identify the designated time slots within the one or more UWB frames.
