This amendment to IEEE Std 802.3-2018 makes technical and editorial corrections and refinements to Power over Ethernet over 2-pairs in Clause 33.

This standard specifies how the Media Access Control (MAC) Service is supported by Bridged Networks, the principles of operation of those networks, and the operation of MAC Bridges and VLAN Bridges, including management, protocols, and algorithms.

The IEEE 802.11 directional multi-gigabit (DMG) physical layer (PHY) and the medium access control (MAC) layer are modified by this amendment to IEEE Std 802.11-2016 to enable operation in the Chinese millimeter wave frequency band around 60 GHz. This amendment also defines modifications to the IEEE 802.11 PHY and MAC layer to enable operation in the Chinese millimeter wave frequency band around 45 GHz.

Protocols, procedures, and managed objects to enhance the ability of IEEE 802.11(TM) media to provide transit links internal to IEEE 802.1Q(TM) bridged networks are specified in this amendment to IEEE Std 802.11(TM)-2016.

Modifications to IEEE Std 802.11(TM)-2016, above the physical layer (PHY), to enable delivery of preassociation service discovery information to IEEE 802.11 stations (STAs) are defined in this amendment.

This standard adopts MIPI Alliance--MIPI A-PHY Specification Version 1.0 as an IEEE Standard. The adopted standard provides an asymmetric data link in a point-to-point or daisy-chain topology, with high-speed unidirectional data, embedded bidirectional control data and optional power delivery over a single cable. In this way, it reduces wiring, cost and weight, as high-speed data, control data and optional power share the same physical wiring. For integration with existing network backbones, it complements Ethernet, Controller Area Network (CAN), FlexRay, and other interfaces.

This corrigendum to IEEE Std 802.1AC-2016 corrects the value of the LLC Encapsulation EtherType.

This document describes a complete communications specification, encompassing layers 1 to 4 of the Open Systems Integration (OSI) network model, for a secure, wireless mesh communications network, using open standards communications and cybersecurity standards from standards organizations including Institute of Electrical and Electronics Engineers (IEEE) and Internet Engineering Task Force (IETF). The specification describes the functionality of the physical (PHY layer), medium access control (MAC layer), the network layer, transport layer and security parameters including certificate format for a highly scaleable and secure wireless mesh network for critical infrastructure ipv6 wireless communications networks.

How all or part of a network can be secured transparently to peer protocol entities that use the MAC Service provided by IEEE 802® LANs to communicate is specified in this standard. MAC security (MACsec) provides connectionless user data confidentiality, frame data integrity, and data origin authenticity.
