One of its tasks is to regulate the use of radio frequencies within the United States. Radio equipment must be certified for compliance with certain technical standards designed to limit interference to other devices. This certification has to be done by the manufacturer. Once this certification is obtained, the user is allowed to operate those devices without any special licence. It is in the responsibility of the user to make sure that he is allowed to operate this device without any additional license. Devices that have FCC certifications come with an ID issued by the FCC, the so called FCCID. There is a database that can conveniently be searched to check such an ID. Each manufacturer gets an ID and every product by that manufacturer gets another ID. So based on the FCCID you can identify the manufacturer and the exact product. For example: FrSky has the grantee ID XYF and the Taranis X-Lite has the product ID XELITET, so the total FCCID for the Taranis X-Lite by FrSky is XYFXELITET. This ID is placed somewhere on the product and allows the user to easily verify that the device complies to FCC regulations. What does LBT mean? LBT stands for Listen Before Talk is also know as listen before transmit. With LBT the device is required to first listen to its environment before it is allowed to transmit. The device has to listen for a free channel before it is allowed to transmit もっと見る
