Class licences do not have to be applied for, and no licence fees are payable. Class licences are 'issued' by the ACA by a notice published in the Commonwealth of Australia Gazette . The Infrared Devices Class Licence supports the use of devices that transmit infrared energy for radiocommunications purposes over short ranges. Infrared Lasers Infrared lasers in radiocommunications applications are used, for example, in distance and speed measurement systems, and in laser link communications systems. Maximum output powers typically vary between 100 microwatts and 125 milliwatts, depending on the application.
Interference is only likely to occur if two or more devices are operated over the exact same path.
Infrared LEDs are typically used for communications purposes in very short range remote control or sensing applications. Maximum output power is typically less than 30 milliwatts. Interference is only likely to occur if the devices are operated in the same location. It should be noted that radiations from laser devices are a potential health hazard . Interference Management Infrared devices operating under the class licence must not cause interference to other radiocommunications services and will not be afforded protection from interference caused by other radiocommunications services.
