IEEE P802.15.4j/D4.0, Sept 2012

P802.15.4j/D4.0, Sept 2012 is a draft amendment to the IEEE 802.15.4 low-rate wireless personal area network framework, focused on an alternative physical layer extension for medical body area network services in the 2360-2400 MHz band. It is relevant to communication, networking, and bioengineering applications where short-range wireless links must be defined with care. For teams evaluating P802.15.4j/D4.0, Sept 2012, the document helps clarify technical direction for MBAN-oriented PHY design and interoperability.

Overview of P802.15.4j/D4.0, Sept 2012

This specification sits within the IEEE 802.15.4 family and addresses an alternative physical layer extension intended to support medical body area network operation in the 2360-2400 MHz band. It is closely tied to low-rate wireless WPANs, where device behavior, channel use, and implementation constraints must be defined precisely. P802.15.4j/D4.0, Sept 2012 is useful when assessing how the amendment fits into existing MAC and PHY structures and how it may affect engineering decisions for medical networking equipment.

Typical use cases

The standard is most relevant for medical body area network systems that rely on short-range wireless links between body-worn, implanted, or nearby sensing devices and associated controllers. It may be used in design work for patient monitoring equipment, portable biomedical sensors, and other low-power wireless devices operating in the 2360-2400 MHz band. It is also useful for teams comparing PHY options, planning interoperability testing, or reviewing how an MBAN-focused implementation aligns with the broader P802.15.4 environment.

Why it matters

In practice, this draft amendment matters because it gives engineers and procurement teams a clearer technical basis for MBAN-related design and verification. Using P802.15.4j/D4.0, Sept 2012 can help support consistent interpretation of physical layer requirements, reduce integration risk, and improve alignment between device behavior and intended medical use. For compliance-oriented projects, it provides a reference point for testing, performance checks, and specification review in a sensitive wireless environment.
