Overview

ISO/IEC 4005-3:2023 - Telecommunications and information exchange between systems - Unmanned aircraft area network (UAAN) - Part 3: Physical and data link protocols for control communication - specifies the physical layer and data link layer protocols for one-to-one control communication between an unmanned aircraft (UA) and its controller. Focused on a wireless distributed communication model (Level II), the standard defines how UAs and controllers establish and maintain robust, interference-managed links in licensed frequency bands.

Key keywords: ISO/IEC 4005-3:2023, Unmanned aircraft area network, UAAN, control communication, physical layer, data link layer, wireless distributed communication, UA controller.

Key Topics and Technical Requirements

The standard covers detailed technical topics and requirements for reliable UA control links, including:

Physical layer specifications
- Channel and frame structure for data channels (number of channels, bandwidth, frame/slot structure, subchannels)
- Channel and frame structure for tone channels (frame structure, slot power, slot block and subslot timing, signal waveform)
- Encoding procedures, synchronization, subchannel power management, measurements and coexistence operation
Data link layer protocols
- General protocol behavior, channel mapping, and measurement processes
- Subchannel negotiation mechanisms (using shared channel, dedicated slot, or initial work resources)
- Resource allocation competition, generated link confirmation, and broadcasting of control channel status
- Subchannel occupation, collision detection and collision management (including collision tone procedures and power control during occupation)
- Reallocation procedures and decision criteria
- Data exchange (packet format) and synchronization
- Data link layer security and interfaces with upper layers and other communication layers
Operational elements
- Initial work resources (IWR), dedicated slots/subchannels, subchannel maps, interference power calculation, and interface definitions for initialization and dynamic control.

Practical Applications and Who Uses This Standard

ISO/IEC 4005-3:2023 is intended for organizations involved in designing, implementing, certifying, and operating UA control communications:

Aerospace and UAV system integrators implementing UA-to-controller links
Telecommunications and radio equipment manufacturers (modems, transceivers)
Regulatory bodies and spectrum managers implementing licensed-band UA communication rules
Test labs and certification bodies validating compliance with UAAN physical and data link requirements
Software developers and network architects building UAAN protocol stacks and control applications
