Identification tag configured for variable intervals between signal transmissions

This is a wireless tag that powers itself by gathering energy from its surroundings. It sends out its unique identification signal at irregular times, meaning the gaps between any three consecutive transmissions are always different. These irregular timings can be based on a set rule or chosen randomly.

Why it matters: Since 2020, advancements in ultra-low-power electronics and ambient energy harvesting have made self-powered, long-duration operation more feasible for compact devices. The increasing demand for privacy and anti-tracking features in ubiquitous sensing applications also makes variable transmission timing more relevant.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
