P802.11z/D4.0, Feb 2009 is an English-language draft standard for wireless LANs that focuses on Part 11 MAC and PHY specifications, specifically Amendment 6: Direct Link Setup. It is relevant to communication, networking, and broadcast technologies where direct station-to-station setup can affect efficiency and network behavior. As a draft specification, P802.11z/D4.0, Feb 2009 is useful for understanding the technical direction of direct link capabilities within IEEE 802.11 systems.

Overview of P802.11z/D4.0, Feb 2009

This document sits within the IEEE 802.11 family and addresses a direct link setup amendment to the wireless LAN Medium Access Control and Physical Layer framework. P802.11z/D4.0, Feb 2009 is intended to define how two wireless devices may establish a direct communication path under the broader WLAN architecture, rather than relying only on the usual infrastructure path. For product teams and technical reviewers, it provides a focused reference point for implementation, interoperability analysis, and draft-stage requirements review.

Typical use cases

P802.11z/D4.0, Feb 2009 is most relevant where WLAN devices need to support direct link establishment in an 802.11 environment. That can include enterprise access points, client devices, embedded wireless modules, and test setups evaluating direct peer connectivity. It may also be useful in product development workflows that assess how stations negotiate and maintain direct communication while still operating within standard WLAN procedures. The specification is closely tied to networking equipment and interoperability testing.

Why it matters

For organizations working with wireless LAN design or procurement, P802.11z/D4.0, Feb 2009 helps clarify the draft requirements around direct link behavior and related MAC/PHY interactions. Using the correct standard reference supports more consistent engineering decisions, better interoperability planning, and more reliable testing against the intended amendment scope. It also helps reduce ambiguity when documenting product capabilities or comparing equipment that may support direct link features under the IEEE 802.11 framework.
