IEEE P802.16.1b/D4 May 2012

P802.16.1b/D4 May 2012 is a technical amendment for machine-to-machine communication, with a focus on enhancing wireless networking behavior for connected devices and systems. As part of the broader P802.16.1 family, it is relevant to communication, networking and broadcast technologies as well as computing and processing applications. This document matters for teams evaluating interoperability, device coordination, and protocol support where automated, low-touch data exchange is a key requirement.

What is P802.16.1b/D4 May 2012?

P802.16.1b/D4 May 2012 is an amendment specification titled Enhancements to Support Machine-to-Machine Applications. It addresses technical changes intended to better support device communication patterns associated with M2M environments, where systems may exchange data with limited human intervention. In practical terms, the standard is used as a reference for defining requirements, comparing implementations, and checking whether equipment behavior aligns with the intended communication model. For organizations working with P802.16.1b/D4 May 2012, it provides a structured basis for design and compliance planning.

Where is P802.16.1b/D4 May 2012 used?

This standard is most relevant in wireless networking and embedded communication scenarios where machine-to-machine links must be coordinated reliably. It may apply to connected modules, controllers, gateways, and other systems that exchange status, telemetry, or control information across a network. The amendment is especially useful where device behavior must be defined for automated operations, integration testing, or product qualification. Because P802.16.1b/D4 May 2012 is tied to enhancements for M2M applications, it fits contexts that depend on predictable device interaction rather than general consumer data traffic.

Why is P802.16.1b/D4 May 2012 important?

P802.16.1b/D4 May 2012 is important because it helps teams work from a defined technical baseline when supporting machine-to-machine communication. That reduces ambiguity during design, procurement, and testing, especially when multiple devices or vendors must interoperate. Using the standard can support more consistent implementation choices, clearer acceptance criteria, and lower integration risk. For inactive standards material, it is also useful as a reference point when reviewing legacy systems or comparing historical requirements against current engineering needs.
