IEEE 802.15.4m-2014

802.15.4m-2014 is a technical standard for low-rate wireless personal area networks focused on TV White Space operation between 54 MHz and 862 MHz. It sits within the broader 802.15.4 family and is relevant to communication, networking and broadcast technologies, as well as components and computing systems that rely on sub-GHz wireless links. This amendment helps define a controlled physical layer for longer-range, low-power connectivity where spectrum availability and coexistence are important.

Overview of 802.15.4m-2014

This standard extends the 802.15.4 framework with physical layer requirements suited to TV White Space frequencies from 54 MHz to 862 MHz. In practical terms, 802.15.4m-2014 addresses how low-rate wireless devices can operate in these bands while maintaining the structure needed for interoperable LR-WPAN designs. It is useful for engineers, integrators, and procurement teams evaluating wireless components, because it defines a specific technical basis for design, testing, and compatibility decisions.

Typical use cases

802.15.4m-2014 is commonly relevant where low-power wireless connectivity is needed over bands below and around traditional 2.4 GHz allocations. Typical applications may include sensor networks, industrial monitoring, building systems, and other embedded communications equipment that must work in TV White Space environments. It can also matter for radio modules, base stations, test setups, and system designs that need a defined physical layer for LR-WPAN deployments in spectrum-constrained or range-sensitive settings.

Why it matters

For product development and compliance work, 802.15.4m-2014 provides a clear reference for assessing whether a device or subsystem is aligned with the intended LR-WPAN physical layer in TV White Space bands. That helps reduce ambiguity in design choices, verification planning, and purchasing decisions. When teams need consistency across radio hardware, firmware behavior, and test expectations, using the correct standard can lower integration risk and support more reliable technical evaluation.
