802.11ai Fast Initial Link Setup

Wi-Fi Optimized Connectivity leverages features from IEEE 802.11ai, IEEE 802.11k, and IEEE 802.11ax to better manage spectrum and network resources, increase mobility, and provide the best possible user experience.

• Select features from IEEE 802.11ai-2016, known as Fast Initial Link Setup (FILS), together with enhancements introduced in IEEE 802.11ax, introduce mechanisms to aid efficient discovery of APs and fast authentication
• New features first introduced in IEEE 802.11-2016 and IEEE 802.11ax provide for enhanced metrics for AP and network selection
• Additional features from IEEE 802.11k focus on informing client devices of channels on which neighboring APs are operating to optimize scanning

Wi-Fi Optimized connectivity relies on several Wi-Fi Alliance features and mechanisms to help optimize network capacity by controlling network access according to received signal strength indication (RSSI), and define a variety of signaling and rules to help ensure consistent, interoperable behavior of devices and APs. Wi-Fi CERTIFIED Agile Multiband™ is also a prerequisite for Wi-Fi Optimized Connectivity, ensuring efficient management of Wi-Fi network resources in changing network environments.

Wi-Fi Agile Multiband: Fast Basic Service Set (BSS) Transition, also known as Fast Transition, is based on IEEE 802.11r. Fast Transition enables devices to reauthenticate quickly with WPA2 security when roaming within the same Wi-Fi network, improving experience with latency sensitive applications such as voice over Wi-Fi.

Wi-Fi Optimized Connectivity: Fast Initial Link Setup (FILS) Authentication is a mechanism defined in IEEE 802.11ai to enable fast authentication to APs.

Devices that are certified for Wi-Fi Vantage represent the most recent and interoperable Wi-Fi technologies for managed networks. Users will experience fewer connection interruptions during calls or video streaming, even while traversing through a transportation hub like a large airport. These devices, when used in a Wi-Fi Vantage enabled network, bring a more seamless and consistent connection and therefore a better mobile experience.

Managed networks are Wi-Fi networks, such as those operated in airports, stadiums, schools, office buildings, retail and hotel locations and other venues, that are “managed” by network administrators to optimize their coverage, performance, and network access. These networks are frequently open to the public or offer access to subscribers.

Future generations of Wi-Fi Vantage will add enhancements in network access, frequency band and channel management, and reduced connection times, resulting in improved roaming and management of Wi-Fi networks.
