IEEE P802.15.4m/D4, Oct 2013

P802.15.4m/D4, Oct 2013 is a draft amendment for low-rate wireless personal area networks that addresses a TV white space physical layer between 54 MHz and 862 MHz. It is relevant to communication, networking, and embedded device work where sub-GHz spectrum, propagation, and coexistence behavior can affect system design. By defining a focused PHY approach for these bands, P802.15.4m/D4, Oct 2013 supports more disciplined engineering and evaluation of LR-WPAN implementations.

P802.15.4m/D4, Oct 2013 overview

This draft sits within the IEEE 802.15.4 family and narrows attention to amendment-level requirements for TV white space operation. P802.15.4m/D4, Oct 2013 is intended to guide how low-rate wireless personal area networks can use spectrum from 54 MHz to 862 MHz at the physical layer, which makes channel behavior, modulation-related choices, and interoperability considerations especially important. For product teams, the document provides a technical reference point for design review, conformance planning, and RF implementation decisions.

Typical use cases

The standard is most relevant to LR-WPAN devices and test programs that need sub-GHz wireless links in challenging propagation environments. Typical applications may include sensor networks, utility monitoring equipment, industrial telemetry, and other embedded systems where longer reach or better wall penetration is useful. It can also matter for component selection, radio module evaluation, and lab verification work involving communication systems that must operate in TV white space conditions. P802.15.4m/D4, Oct 2013 is therefore useful wherever a defined low-rate PHY is needed for planning and validation.

Why this standard matters

For engineering and procurement teams, P802.15.4m/D4, Oct 2013 helps reduce ambiguity when evaluating whether a wireless design is aligned with a specific LR-WPAN amendment. Clear technical scope supports more consistent testing, better comparison of candidate radios, and fewer integration surprises during development. It can also improve compliance workflows by giving teams a common reference for physical-layer expectations in the 54 MHz to 862 MHz range. That consistency is valuable when performance, coexistence, and deployment risk all depend on the chosen wireless profile.
