Abstract

A communications method and device that enables multiple source devices (110, 120, 130) to communicate information to a destination device (100) is disclosed. The information communicated from any source device to the destination device (100) typically takes the form of binary electronic product codes ('EPC') or identification ('ID') information. The preferred embodiment of the invention utilizes the techniques of: data scrambling and descrambling; channel selection and transmission; enabling and disabling group transmissions; correlation; and collision mitigation.
