IEEE 802.11k was implemented to specify and control WLAN and radio characteristics and data that impact network performance. Specifications include network data exposure; channel selection and orchestration; signal strength management and optimal access point (AP) selection.
IEEE 802.11k optimizes network performance by allowing a wireless subscriber to select an AP based on its active subscribers and overall traffic. For example, if there is an AP in close proximity with high traffic, versus an AP with less traffic but not in close proximity, IEEE 802.11k recommends using the latter AP, due to its faster throughput capability.
