IEEE P802.15.4d/D3, Jan 2009

P802.15.4d/D3, Jan 2009 is a draft standard for low-rate wireless personal area networks, focused on an alternative physical layer extension for the Japanese 950 MHz band. It sits within IEEE 802.15.4 MAC and PHY specifications and is relevant to communication, networking, and broadcast technologies where short-range wireless links must follow defined spectrum and interoperability requirements. For teams working with LR-WPAN designs, this document helps clarify the technical direction of P802.15.4d/D3, Jan 2009.

What is P802.15.4d/D3, Jan 2009?

This document is part of the IEEE 802.15.4 family and addresses an amendment to the wireless MAC and PHY framework for low-rate wireless personal area networks. Its purpose is to define an alternative physical layer extension intended to support operation in the Japanese 950 MHz band. As a draft, P802.15.4d/D3, Jan 2009 is typically used to review technical requirements, align implementation expectations, and support development work before finalization or adoption.

Where is P802.15.4d/D3, Jan 2009 used?

P802.15.4d/D3, Jan 2009 is most relevant in the design and evaluation of short-range wireless devices intended for the 950 MHz band in Japan. Common use cases may include embedded wireless modules, sensor-network equipment, industrial monitoring nodes, and other LR-WPAN products that rely on low power and modest data rates. It is also useful in engineering workflows that require band-specific PHY planning, interoperability checks, and compliance-oriented review of wireless implementations.

Why is P802.15.4d/D3, Jan 2009 important?

This standard matters because it provides a structured basis for designing and comparing wireless solutions against a defined amendment to IEEE 802.15.4. For manufacturers and engineers, P802.15.4d/D3, Jan 2009 can support consistency in PHY behavior, reduce ambiguity during testing, and improve confidence when targeting the Japanese 950 MHz band. It also helps procurement and compliance teams identify the exact technical document associated with a draft LR-WPAN extension.
