Wi-Fi Multimedia (WMM) or Wireless Multimedia Extensions is a Wi-Fi Alliance interoperability certification based on the IEEE 802.11e standard. It offers basic QoS (Quality of Service) features for IEEE 802.11 networks. There are a number of Wi-Fi Alliance certification programs: RivieraWaves 802.11ax MAC – IP Modem already widely licensed for integration into low-power IoT SoCs As major sponsors, the alliance list Apple, Comcast, Samsung, Sony, LG, Intel, Dell, Broadcom, Cisco, Qualcomm, Motorola, Microsoft, Instruments, Texas and T-Mobile. The charter for this independent organization was to conduct tests, certify the interoperability of products and promote technology.  The Wi-Fi Alliance offers two-tier certification tests: The holder of a certification mark is responsible for defining the standard defined by the brand. The licensee may accept the trademark and register it with the Trademark Office of Canada as long as it does not manufacture, sell, lease or lease the products itself or provide the services associated with obtaining the certification mark. A certification sign is a special mark used to identify goods or services of a defined standard: Linksys will continue to operate the LCM1 platform for the offered life of 5 years, and then end the life of the service. Once access points have been updated, this 5-year cloud license for LCM1 will be replaced by the new licensing conditions for LCM2. Under Canada`s Trademark Act, a “brand” can be defined as one of four things: Agile Multiband Wi-Fi certification indicates that devices can automatically connect and maintain the connection in the most appropriate way. It covers the IEEE 802.11k standard on the Access Point information report, IEEE 802.11v for the exchange of network status information, IeEE 802.11u on additional information from a Wi-Fi network, IEEE 802.11r on fast roaming between different access points and other technologies specified by the Wi-Fi Alliance. TDLS, or Tunneled Direct Link Setup, is “a seamless way to spread media and other data more quickly between devices that are already on the same Wi-Fi network,” based on IEEE 802.11z and the Alliance Wi-Fi certification program in 2012. The devices that use it communicate directly with each other without including the wireless network router.
 The Wi-Fi alliance`s definition for interoperability requires products in typical network configurations to perform well and support established and emerging applications. The Alliance wi-fi certification process includes three types of testing to ensure interoperability. Wi-Fi-certified products are tested for: Here are some examples of certification brands. Vantage Wi-Fi, formerly known as the Wi-Fi Carrier, is a certification program for operators to maintain and manage high-quality Wi-Fi connections in a high-use environment.  It contains a number of certifications, such as z.B. Certified Wi-Fi (as in 802.11ac), Passpoint, Agile Multiband and optimized connectivity.  Wi-Fi EasyMesh is a certification program based on its Multi-Access Point specification for the creation of Wi-Fi networks from products from different manufacturers, based on IEEE 1905.1.
