IEEE has announced updates to four wireless communications technologies in the 802 family of standards, as well as a new IEEE 802 standards development project. The new standards support the global utility industry’s needs for smart grid data communications infrastructure and build on the IEEE Standards Association (IEEE-SA) portfolio of more than 100 active IEEE standards or standards in development pertaining to the smart grid.
The new standards include the following:
* IEEE 802.15.4g-2012 – IEEE Standard for Local and Metropolitan Area Networks – Part 15.4: Low-Rate Wireless Personal Area Networks (LR-WPANs) Amendment 3: Physical Layer (PHY) Specifications for Low-Data-Rate, Wireless, Smart Metering Utility Networks – is a global standard that provides carrier-grade wireless communications connectivity for very large-scale smart metering applications and advanced metering infrastructure used in smart grids.
It supports geographically diverse networks with minimal infrastructure that can potentially connect millions of end points. The new standard, an amendment to IEEE 802.15.4, offers the communications range, robustness and coexistence characteristics required for these types of applications and deployments that fit the general objectives of IEEE 802.15 but were not covered by the existing standard.
* IEEE 802.16-2012 – IEEE Standard for Air Interface for Broadband Wireless Access Systems. This standard supports worldwide deployment of innovative, cost-effective, interoperable and multi-vendor broadband wireless access (BWA) products, with Ethernet as well as IP interfaces, that utilities can use for machine-to-machine smart grid applications.
The standard specifies the air interface, including the medium access control and physical layers (MAC and PHY), of combined fixed and mobile point-to-multipoint BWA systems. The standard updates the WirelessMAN-OFDMA air interface designated by the ITU as IMT-2000.
Further enhancement relevant to smart grid applications are provided in IEEE 802.16p-2012, an amendment providing “Enhancements to Support Machine-to-Machine Applications.”
* IEEE 802.16.1-2012 – IEEE Standard for WirelessMAN-Advanced Air Interface for Broadband Wireless Access Systems – provides an enhanced air interface and improved capacity for metropolitan-area networks that utilities can use for smart grid machine-to-machine communications, as well as mobile voice-based applications, with support for Ethernet as well as IP interfaces.
IEEE 802.16.1-2012 is a new standalone version of the technology first specified in IEEE 802.16m-2011 and designated by the ITU as IMT-Advanced. Further enhancements relevant to smart grid applications are provided in IEEE 802.16.1b-2012, an amendment providing “Enhancements to Support Machine-to-Machine Applications.”
In addition, the IEEE-SA has approved development of a new standard that is intended to enable the handover of groups of wireless data connections between different types of networks in a heterogeneous network. Utilities will be able to use the standard to allow large groups of devices to hand over from one network to another to ensure continuous connectivity and service reliability if a part of the network loses connectivity.
* IEEE P802.21d – Standard for Local and Metropolitan Area Networks—Part 21: Media Independent Handover Services Amendment: Multicast Group Management – is intended to amend IEEE 802.21-2008 by adding support for simultaneous handovers of multiple users.
