IEEE 802.11r-2008 or fast BSS transition (FT), is an amendment to the IEEE 802.11 standard to permit continuous connectivity aboard wireless devices in motion, with fast and secure client transitions from one Basic Service Set (abbreviated BSS, and also known as a base station or more colloquially, an access point) to another performed in a nearly seamless manner.
Cisco Centralized Key Management (CCKM) is a form of Fast Roaming and a subset of the Cisco Compatible EXtensions (CCX) specification.. When a wireless LAN is configured for fast reconnection, a Lightweight Extensible Authentication Protocol (LEAP) enabled client device can roam from one wireless access point to another without involving the main server.
The IEEE 802.11 standard doesn't specify the communications between access points in order to support users roaming from one access point to another and load balancing. The 802.11 working group purposely did not define this element in order to provide flexibility in working with different wired and wireless distribution systems (i.e., wired ...
IEEE 802.11ai is a Wireless LAN standard from IEEE that since June 2017 [1] provides fast initial link setup (FILS) methods that enable a wireless LAN client to achieve a secure link setup within 100ms, designed to improve dense environments. [1] FILS provides fast roaming without 802.11r. [2]
The Cisco Compatible Extensions (CCX) Specification describes a list of functional extensions to the IEEE 802.11 Wireless LAN standard to support fast roaming with upgraded security, reliability, and diagnostic performance. This specification is Cisco proprietary and a device manufacturer requires a Cisco license agreement in order to develop ...
IEEE 802.11k-2008 is an amendment to IEEE 802.11-2007 standard for radio resource measurement.It defines and exposes radio and network information to facilitate the management and maintenance of a mobile Wireless LAN.
Disaster roaming has also been activated in the hard-hit state, which allows any customer to connect to any provider's working network, according to a release from Gov. Roy Cooper.
However, such communications are restricted by delays and limited bandwidth. Wireless ad hoc networks enable ship-area-networks to be formed while at sea, enabling high-speed wireless communications among ships, enhancing their sharing of imaging and multimedia data, and better co-ordination in battlefield operations.
