Malaysia: Guidelines for the Use of Radio Spectrum for Unmanned Aircraft Systems

MCMC’s guidelines are designed to support the safe operation of UAS by addressing the radio spectrum and certification requirements for communications equipment. These guidelines apply to all types of UAS, regardless of size, weight, or function. Some of the key information found in the guidelines includes: 

UAS Communication Subsystems 

• CNPC (Command and Non-Payload Communications): Critical for safe UAS operations, this system handles telecommand messages, telemetry, navigation aids, and air traffic control data.
• Payload Communications: Used for real-time data streaming, such as video links. These systems are not critical to safety but are essential for specific applications. 
• DAA (Detect and Avoid): Supports collision avoidance capabilities, ensuring UAS operate safely without interfering with obstacles. 
•  

Frequency Bands Identified for UAS Use 

• Terrestrial CNPC Links: The frequency band from 5030 MHz to 5091 MHz is designated for CNPC links under the Aeronautical Mobile (R) Service (AM(R)S). 
• Satellite Communications: UAS satellite links can utilize the 1525 MHz to 1559 MHz and 1616 MHz to 1660.5 MHz frequency bands under the AMS(R)S and Mobile Satellite Service (MSS) allocations. 
• License-Exempt Bands: Commonly used frequencies such as 433 MHz to 435 MHz, 2400 MHz to 2500 MHz, and 5725 MHz to 5875 MHz are allocated for UAS communications.
