old Wi-Fi Alliance logo
Wi-Fi Alliance is a non-profit organization that promotes
technology and certifies Wi-Fi products if they conform to certain standards of . Not every -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-Fi . Manufacturers may use the trademark to brand certified products that have been tested for interoperability.
Early 802.11 products suffered from interoperability problems because the
(IEEE) had no provision for testing equipment for compliance with its standards. In 1999, pioneers of a new, higher speed variant, endorsed the
specification to form the Wireless Ethernet Compatibility Alliance (WECA) and branded the new technology Wi-Fi.
The group of companies included , Aironet (acquired by ),
As key sponsors, the alliance lists , , , , , , , , , , , , , and . The charter for this independent organization was to perform testing, certify interoperability of products, and to promote the technology.
WECA renamed itself the Wi-Fi Alliance in 2002. It is based in .
Most producers of 802.11 equipment became members, and as of 2012, the Wi-Fi Alliance had over 550 member companies. Wi-Fi Alliance extended Wi-Fi beyond
applications into point-to-point and personal area networking and enabled specific applications such as .
The Wi-Fi Alliance owns and controls the "Wi-Fi Certified" , a registered , which is permitted only on equipment which has passed testing. Purchasers relying on that trademark will have greater chances of interoperation than otherwise. Testing involves not only radio and data format interoperability, but , as well as optional testing for quality of service and power management protocols. A focus on user experience has shaped the overall approach of the Wi-Fi Alliance certification program: 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. This pragmatic approach stems from three tenets, around which certification is centered:
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.
Innovation is supported through the introduction of new certification programs as the latest technology and specifications come into the marketplace. These certification programs may be mandatory (e.g. ) or optional (e.g. ). Equipment vendor differentiation and inventiveness are preserved in areas that are not covered by certification testing.
The Wi-Fi Alliance definition of interoperability goes well beyond the ability to work in a Wi-Fi network. To gain certification under a specific program, products have to show satisfactory performance levels in typical
configurations and have to support both established and emerging applications. A user that purchases a Wi-Fi enabled laptop, for instance, would not be satisfied if the laptop established a connection with the home network, only to get the throughput of a dial-up connection. Similarly, subscribers using a Wi-Fi enabled mobile phone would be disappointed, if a voice call could not go through or was dropped. 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. Compatibility testing is the program component that helps to ensure devices purchased today will work with Wi-Fi Certified devices already owned or purchased in the future.
Conformance: the equipment conforms to specific critical elements of the
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 to meet end-user expectations in support of key applications. Performance tests are not designed to measure and compare performance among products, but simply to verify that the product meets the minimum performance requirements for a good user experience as established by the Wi-Fi Alliance. Specific performance tests results are not released by the Wi-Fi Alliance.
The Wi-Fi Alliance provides certification testing in two levels:
Mandatory:
Core MAC/PHY interoperability over , , , and . (at least one)
Wi-Fi Protected Access 2 (WPA2) security, which aligns with IEEE 802.11i. WPA2 is available in two types: WPA2-Personal for consumer use, and WPA2 Enterprise, which adds EAP authentication.
Tests corresponding to IEEE 802.11h and 802.11d.
Quality of Service, based upon a subset of IEEE 802.11e.
WMM Power Save, based upon APSD within IEEE 802.11e
, 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
In October 2010, the Alliance began to certify , that allows Wi-Fi-enabled devices to communicate directly with each other, without going through a
or hotspot. Since 2009 when it was first announced, some suggested Wi-Fi Direct might replace the need for
on applications that do not rely on .
Wi-fi Aware(TM) is a interoperability certification program launched 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.
