Abstract: This document describes improvements in range and reliability for wireless mesh networks implementing IEEE 802.11 networking technologies. Reducing the number of spatial streams, N, to a lower value at middle and far distance ranges using an optimized rate control algorithm, preemptively trades off a lower throughput limit for a higher link budget. This higher link budget provides longer range and higher RF link reliability by using an N×N spatial diversity of MIMO RF channels for maximizing link budget instead of network throughput.

Abstract: This document describes methods, devices, systems, and means for controlling wireless devices using aggregated data from cross-network access points. An access point (AP) provides operational information from a plurality of different types of client devices communicating with the AP to a cloud service and obtains per-client-device-type policy data from the cloud service that is based on aggregated operational information from a plurality of different types of client devices from different AP networks. The AP controls, using a wireless transceiver, a wireless client device that is of a first type, using the per-client-device-type policy data for the first type based on aggregated operational information from a plurality of different types of client devices from different AP networks.
