IEEE 802.15.4w-2020

The existing low-energy critical infrastructure monitoring (LECIM) frequency shift keying (FSK) physical layer of IEEE Std 802.15.4-2020 is extended to be more robust in the presence of interference and achieve higher link budgets for applications in low power wide area networks (LPWAN). Lower symbol rates and a split mode with low-rate forward error correction (FEC) codes are introduced to achieve this goal.

IEEE 802.15.4x-2019

Enhancements to the IEEE 802.15.4(TM) smart utility network (SUN) orthogonal frequency division multiplexing (OFDM) physical layers (PHYs) that enable support for data rates up to 2.4 Mb/s are defined by this amendment to IEEE Std 802.15.4(TM)-2015. This amendment also defines additional channel plans, as needed, to support emerging applications.

IEEE 802.3cg-2019

This amendment to IEEE Std 802.3-2018 specifies additions and appropriate modifications to add 10 Mb/s Physical Layer (PHY) specifications and management parameters for operation, and associated optional provision of power, over a single balanced pair of conductors.

IEEE 1679.1-2017

Guidance for an objective evaluation of lithium-based energy storage technologies by a potential user for any stationary application is provided in this document. IEEE Std 1679-2010, IEEE Recommended Practice for the Characterization and Evaluation of Emerging Energy Storage Technologies in Stationary Applications is to be used in conjunction with this document. Secondary (rechargeable) electro-chemistries with lithium ions as the active species exchanged between the electrodes during charging and discharging are included in the category of lithium-based batteries for the purposes of this document. Lithium-ion, lithium-ion polymer, lithium-metal polymer, and lithium-sulfur batteries are examples of secondary lithium-based batteries. Primary (non-rechargeable) lithium…

IEEE 802.1AE-2018

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.(The PDF of this standard is available at no cost to you compliments of the IEEE GET program https://ieeexplore.ieee.org/browse/standards/get-program/page)

IEEE C62.35-2010/Cor 1-2018

Superseded by C62.59-2019. Avalanche breakdown diodes used for surge protection on systems with voltages equal to or less than 1000 V rms or 1200 V dc are discussed in this standard. The avalanche breakdown diode surge suppressor is a semiconductor diode that can operate in either the forward or reverse direction of its V-I characteristic. This component is a single package, which may be assembled from any combination of series and/or parallel diode chips. This standard contains definitions, service conditions, and a series of test criteria for determining the electrical characteristics and verifying ratings of these avalanche breakdown diodes. If…

IEEE 802.3-2018

Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 400 Gb/s using a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted pair or fiber optic cables, or electrical backplanes. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up…

IEEE 802.19.1-2018

This standard specifies radio technology independent methods for network-based coexistence among dissimilar or independently operated networks of unlicensed devices and dissimilar unlicensed devices. The standard is defined for geo-location capable devices operating under general authorization such as TV band White Spaces, the 5 GHz license-exempt bands and the general authorized access the 3.5 GHz bands.
