IEEE Draft Standard for Low-Rate Wireless Network Amendment 1: Enhanced Ultra Wide-Band (UWB) Physical Layers (PHYs) and Associated Medium Access and Control (MAC) sublayer Enhancements

This amendment enhances the Ultra Wideband (UWB) physical layers (PHYs) medium access control (MAC), and associated ranging techniques while retaining backward compatibility with enhanced ranging capable devices (ERDEVs). Areas of enhancement include: additional coding, preamble and modulation schemes to support improved link budget and/or reduced air-time; additional channels and operating frequencies; interference mitigation techniques to support greater device density and higher traffic use cases; improvements to accuracy, precision and reliability and interoperability for high-integrity ranging; schemes to reduce complexity and power consumption; definitions for tightly coupled hybrid operation with narrowband signaling to assist UWB; enhanced native discovery and connection setup mechanisms; UWB sensing capabilities to support presence detection and environment mapping; and mechanisms supporting low-power low-latency streaming as well as high data-rate streaming allowing at least 50 Mbit/s of throughput; and, support for peer-to-peer, peer-to-multi-peer, and station-to-infrastructure protocols and infrastructure synchronization mechanisms.
