Abstract

An ambient internet of things, AIoT, device is configured to have more than two different states that are needed for channel coding and modulation with backscattering, such as an increased radio reflection coefficient that is closer to one than in normal backscattering. The AIoT device is configurable to at least an energy harvesting state in which the radio reflection coefficient is as close to zero as possible; a normal operation state in which the radio reflection coefficient higher but clearly below one to allow sufficient energy harvesting for various circuitries, such as processing and volatile memory circuitries; and a range extending state in which the radio reflection coefficient is as close to zero as possible so as to reach maximum range for outgoing data that is backscattered.
