Abstract
The present description concerns a radio transmission device including a plurality of elementary cells, each including a transmit circuit and an antenna connected to an output terminal of the transmit circuit, each transmit circuit including a power detector coupled to its output terminal, the device further including a control circuit configured to: a) simultaneously activating in transmit mode a first cell, deactivating in transmit mode a second cell, and reading from an output node of the power detector of the second cell a signal representative of a radio frequency power received on the output terminal of the second cell via the antenna of the second cell; and b) deducing from the signal read at step a) information relative to the state of the device or of its environment.
