BEAVERTON, Ore.--(BUSINESS WIRE)--The Consortium for Smart Energy Profile 2 Interoperability announced its formal incorporation, with founding members HomePlug® Alliance, Wi-Fi Alliance® and ZigBee® Alliance continuing a clear path to SEP 2 interoperability for consumer benefits in the smart grid market.

Launched in October 2011, the Consortium will create and maintain a certification test suite to validate interoperability for a variety of wired or wireless devices. This will provide the Smart Grid ecosystem – including utilities, service providers, product vendors and consumers – confidence in application and device interoperability while accelerating the availability of products and services. Products to be certified as a result of the Consortium’s work are expected to include thermostats, appliances, electric meters, gateways, electric vehicles and countless other devices in the Smart Grid.

The Consortium successfully finished its first interoperability Plugfest that tested the interoperability of products built using either HomePlug, Wi-Fi or ZigBee communications. More Plugfests will be conducted over the coming months as the Consortium moves to complete its certification program.

“The CSEP incorporation further solidifies the industry’s commitment to collaboration and delivery of interoperable SEP 2 solutions,” said Edgar Figueroa, Consortium chairman. 'CSEP incorporation is an important step toward establishing the Consortium as the recognized creator of the SEP 2 test plans and tools required to ensure interoperability across multiple communications technologies.'

SEP 2 is an Internet Protocol-based application layer whose development involves the ZigBee Alliance partnering with Wi-Fi Alliance, HomePlug Alliance and other organizations. The Smart Energy 2.0 Working Group expects to complete the SEP 2 Application Specification in Q4 2012. SEP 2 was selected in 2009 by the United States National Institute of Standards and Technology (NIST) as a standard for home energy management devices.

Wireless Ethernet Compatibility Alliance

Wi-Fi Alliance is a non-profit organization that promotes Wi-Fi technology and certifies Wi-Fi products for conformity to certain standards of interoperability. Not every IEEE 802.11-compliant device is submitted for certification to the Wi-Fi Alliance, sometimes because of costs associated with the certification process. The lack of the Wi-Fi logo does not necessarily imply a device is incompatible with Wi-Fi devices.

The Wi-Fi Alliance owns the Wi-Fitrademark. Manufacturers may use the trademark to brand certified products that have been tested for interoperability.

  • 2Wi-Fi certification
  • 3Certification programs

History[edit]

Early 802.11 products suffered from interoperability problems because the Institute of Electrical and Electronics Engineers (IEEE) had no provision for testing equipment for compliance with its standards.In 1999, pioneers of a new, higher speed variant, endorsed the IEEE 802.11b specification to form the Wireless Ethernet Compatibility Alliance (WECA) and branded the new technology Wi-Fi.[1][2]

The group of companies included 3Com, Aironet (acquired by Cisco), Harris Semiconductor (now Intersil), Lucent (was Alcatel-Lucent, then acquired by Nokia), Nokia and Symbol Technologies (now Zebra Technologies).[3]

As key sponsors, the alliance lists Apple, Comcast, Samsung, Sony, LG, Intel, Dell, Broadcom, Cisco, Qualcomm, Motorola, Microsoft, Texas Instruments, and T-Mobile. The charter for this independent organization was to perform testing, certify interoperability of products, and to promote the technology.[4]

WECA renamed itself the Wi-Fi Alliance in 2002.[5] It is based in Austin, Texas.

Itu Sectors

Most producers of 802.11 equipment became members, and as of 2012, the Wi-Fi Alliance included over 550 member companies. Wi-Fi Alliance extended Wi-Fi beyond wireless local area network applications into point-to-point and personal area networking and enabled specific applications such as Miracast.

Wi-Fi certification[edit]

The Wi-Fi Alliance owns and controls the 'Wi-Fi Certified' logo, a registered trademark, which is permitted only on equipment which has passed testing. Purchasers relying on that trademark may have greater chances of interoperation than otherwise. Testing involves not only radio and data format interoperability, but security protocols, as well as optional testing for quality of service and power management protocols.[6] Wi-Fi Certified products have to demonstrate that they can perform well in networks with other Wi-Fi Certified products, running common applications, in situations similar to those encountered in everyday use. Certification employs 3 principles:

  • Interoperability is the primary target of certification. Rigorous test cases are used to ensure that products from different equipment vendors can interoperate in a wide variety of configurations.
  • Backward compatibility has to be preserved to allow for new equipment to work with existing gear. Backward compatibility protects investments in legacy Wi-Fi products and enables users to gradually upgrade and expand their networks.
  • New certification programs allow newer technology and specifications come into the marketplace. These certification programs may be mandatory (e.g. WPA2) or optional (e.g. WMM).

The Wi-Fi Alliance definition of interoperability demands that products have to show satisfactory performance levels in typical network configurations and have to support both established and emerging applications. The Wi-Fi Alliance certification process includes three types of tests to ensure interoperability. Wi-Fi Certified products are tested for:

  • Compatibility: certified equipment has been tested for connectivity with other certified equipment . Compatibility testing has always been, and still is, the predominant component of interoperability testing, and it is the element that most people associate with 'interoperability'. It involves tests with multiple devices from different equipment vendors
  • Conformance: the equipment conforms to specific critical elements of the IEEE802.11 standard. Conformance testing usually involves standalone analysis of individual products and establishes whether the equipment responds to inputs as expected and specified. For example, conformance testing is used to ensure that Wi-Fi equipment protects itself and the network when the equipment detects evidence of network attacks.
  • Performance: the equipment meets the performance levels required. Performance tests are not designed to measure and compare performance among products, but simply to verify that the product meets the minimum performance requirements. Specific performance tests results are not released by the Wi-Fi Alliance.

Certification types[edit]

The Wi-Fi Alliance provides certification testing in two levels:[7]

Mandatory:

  • Core MAC/PHY interoperability over 802.11a, 802.11b, 802.11g, and 802.11n. (at least one)
  • Wi-Fi Protected Access 2 (WPA2) security,[8] which aligns with IEEE 802.11i. WPA2 is available in two types: WPA2-Personal for consumer use, and WPA2 Enterprise, which adds EAP authentication.

Optional:

  • Tests corresponding to IEEE 802.11h and 802.11d.
  • WMM Quality of Service,[9] based upon a subset of IEEE 802.11e.
  • WMM Power Save,[10] based upon APSD within IEEE 802.11e
  • Wi-Fi Protected Setup,[11] a specification developed by the Alliance to ease the process of setting up and enabling security protections on small office and consumer Wi-Fi networks.
  • Application Specific Device (ASD), for wireless devices other than Access Point and Station which has specific application, such as DVD players, projectors, printers, etc.
  • Converged Wireless Group–Radio Frequency (CWG-RF, offered in conjunction with CTIA), to provide performance mapping of Wi-Fi and cellular radios in converged devices.
  • Passpoint/Hotspot 2.0[12]

Certification programs[edit]

There are a number of certification programs by Wi-Fi alliance:[13]

Wi-Fi Direct[edit]

In October 2010, the Alliance began to certify Wi-Fi Direct, that allows Wi-Fi-enabled devices to communicate directly with each other by setting up ad-hoc networks, without going through a wireless access point or hotspot.[17][18] Since 2009 when it was first announced, some suggested Wi-Fi Direct might replace the need for Bluetooth on applications that do not rely on Bluetooth low energy.[19][20]

WPA[edit]

Wi-Fi Protected Access is a security mechanism based on IEEE 802.11i amendment to the standard that the Wi-Fi Alliance started to certify from the year of 2003.[21]

IBSS with Wi-Fi Protected Setup[edit]

IBSS with Wi-Fi Protected Setup would enable the creation of ad hoc network between devices directly without central access point.[22]

Wi-Fi Aware[edit]

Wi-Fi Aware is an interoperability certification program announced in January 2015 that enables device users, when in the range of a particular access point or another compatible device, to receive notifications of applications or services available in the proximity.[26][27] Later versions of this standard included new features such as the capability to establish a peer-to-peer data connection for file transfer.[28][28]

Fears were voiced immediately in media that it would be predominantly used for proximity marketing.[29]

Wi-Fi Location[edit]

Wi-Fi Location is a type of Wi-Fi positioning system, and the certification could help providing accuracy to in-door positioning.[30]

TDLS[edit]

TDLS, or Tunneled Direct Link Setup, is 'a seamless way to stream media and other data faster between devices already on the same Wi-Fi network' based on IEEE 802.11z and added to Wi-Fi Alliance certification program in 2012. Devices using it communicate directly with one another, without involving the wireless network's router.[31]

Wi-Fi Agile Multiband[edit]

The certification of Wi-Fi Agile Multiband indicate devices can automatically connect and maintain connection in the most suitable way. It cover the IEEE 802.11k standard about access point information report, the IEEE 802.11v standard that enable exchanging information about state of network, IEEE 802.11u standard about additional information of a Wi-Fi network, IEEE 802.11r about fast transition roaming between different access points, as well as other technologies specified by Wi-Fi alliance.[32]

Wi-Fi EasyMesh[edit]

Wi-Fi EasyMesh is a certification program based on its Multi-Access Point specification for creating Wi-Fi meshes from products by different vendors,[33] based on IEEE 1905.1. It it is intended to address the problem of Wi-Fi systems that need to cover large areas where several routers serve as multiple access points, working together to form a larger/extended and unified network.[34][35][36]

Wi-Fi Vantage[edit]

Formerly known as Carrier Wi-Fi, Wi-Fi Vantage is a certification program for operators to maintain and manges quality Wi-Fi connections in high usage environment.[37] It includes a number of certification, such as Wi-Fi certified ac (as in 802.11ac), Passpoint, Agile Multiband, and Optimized Connectivity.[38]

WMM[edit]

Wi-Fi Multimedia (WMM) or known as Wireless Multimedia Extensions is a Wi-Fi Alliance interoperability certification based on the IEEE 802.11e standard. It provides basic Quality of service (QoS) features to IEEE 802.11 networks.
