UDP Stream
User Datagram Protocol data streaming - a method for transmitting RTLS data over networks. UDP provides low-latency, connectionless transmission suitable for real-time position updates. Trades reliability for speed - acceptable for position data where occasional lost packets don't critically impact operations.
UDP Stream in industrial RTLS refers to real-time position data transmission using User Datagram Protocol (UDP), a connectionless network protocol that delivers location updates to applications with minimal latency and overhead. Update rates for UDP streaming vary by application: 1-5 Hz for general asset tracking balancing data freshness with network load, 10-20 Hz for dynamic applications like AGV navigation or worker safety requiring rapid updates, and adaptive rates where update frequency varies by tag motion state (faster when moving, slower when stationary). Challenges with UDP streaming include: packet loss in congested networks or with unreliable connectivity (typical industrial networks experience 0.1-2% packet loss even under normal conditions), out-of-order delivery requiring applications implement sequence numbering and reordering logic, no flow control causing potential receiver overload if applications cannot process packets as fast as transmitted, and no delivery confirmation making it difficult to detect communication failures. UDP streaming performance characteristics: latency typically 5-50 milliseconds from position calculation to application receipt (depending on network topology and congestion), throughput supporting thousands of position updates per second on modern network infrastructure (1 Gbps Ethernet easily handles 10,000 positions/second at 100 bytes per position), and scalability where single positioning server can stream to multiple applications without per-connection overhead. Comparing UDP to alternative protocols: TCP provides reliable, ordered delivery but higher latency (10-100+ milliseconds connection overhead) and connection state management limiting scalability to many consumers. WebSockets offer bidirectional communication over persistent connections, useful for web applications but with connection overhead.
