Advanced large distance optical free-space link on the infrared diode in nanosecond pulsed mode

In the paper, the brief performances of wireless communication systems are represented and their disadvantages are considered. The infrared diode in nanosecond pulsed mode was investigated. The new multipurpose circuit of infrared transmitter block for wireless free-space communication systems is offered. Using modification of infrared diode and enhanced method of radiation, up to 100 Mbps transfer rate can be achieved.
