An access point comprising an optical wireless communication device including: - a processing component (14; 114) arranged to produce transmitted digital signals during transmission periods (Pe); - a digital-to-analog converter (15; 115) arranged to produce transmitted analog signals from the transmitted digital signals; - a light source (24; 124) arranged to produce transmitted light signals from the transmitted analog signals; - a shutdown circuit (25; 125) arranged to selectively activate or deactivate the light source; characterized in that the processing component comprises a binary output (40; 140) and is arranged to generate and apply to the binary output a binary control signal (Sbc) which is in a first state during the transmission periods and in a second state outside the transmission periods, the shutdown circuit being arranged to receive the binary control signal, and to activate the light source when the binary control signal is in the first state and to deactivate the light source when the binary control signal is in the second state, in that the processing component is arranged to transmit, during search cycles, transmitted digital signals containing search frames for searching peripherals that may be connected to the access point, and in that each search cycle comprises at least one transmission period and at least one silence period, a sum of the silence periods being at least 10 times longer than a sum of the transmitting periods, so that during a search cycle, the binary control signal is in the first state for a first duration at least 10 times shorter than a second duration during which the binary control signal is in the second state. - a processing component (14; 114) arranged to produce transmitted digital signals during transmission periods (Pe); - a digital-to-analog converter (15; 115) arranged to produce transmitted analog signals from the transmitted digital signals; - a light source (24; 124) arranged to produce transmitted light signals from the transmitted analog signals; - a shutdown circuit (25; 125) arranged to selectively activate or deactivate the light source; characterized in that the processing component comprises a binary output (40; 140) and is arranged to generate and apply to the binary output a binary control signal (Sbc) which is in a first state during the transmission periods and in a second state outside the transmission periods, the shutdown circuit being arranged to receive the binary control signal, and to activate the light source when the binary control signal is in the first state and to deactivate the light source when the binary control signal is in the second state, in that the processing component is arranged to transmit, during search cycles, transmitted digital signals containing search frames for searching peripherals that may be connected to the access point, and in that each search cycle comprises at least one transmission period and at least one silence period, a sum of the silence periods being at least 10 times longer than a sum of the transmitting periods, so that during a search cycle, the binary control signal is in the first state for a first duration at least 10 times shorter than a second duration during which the binary control signal is in the second state.
