Deterministic Jitter Bound (<1 µs)
Sub-Microsecond Packet Delay Variation Requirement for 6G
Guarantee that packet arrival time variation across the network does not exceed 1 microsecond for time-sensitive industrial synchronization.
Technical Explanation
In modern cyber-physical automation (such as printing presses, robotic welding, and electrical sub-station synchrophasors), high throughput is meaningless if packets arrive with fluctuating delay (jitter). The 6G deterministic jitter bound guarantees that packet arrival variation remains strictly below 1 microsecond. This is achieved via IEEE 802.1 Time-Sensitive Networking (TSN) integration and synchronous cyclic queuing and forwarding (CQF) across the 6G user plane.
Key Functions
- Caps end-to-end packet arrival time variation strictly below 1 microsecond
- Synchronizes distributed robotics and electrical actuators without physical timing cables
- Replaces legacy proprietary fieldbuses (Profinet, EtherCAT) with standard 6G wireless
- Implements Cyclic Queuing and Forwarding (CQF) across core and radio routers
