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 techniques and devices to detect and classify human and animal presence and/or motion based on changes in the interaction of the human or animal with Wireless Local Area Network (WLAN) radio frequency (RF) signals within or about a building structure, such as a home or office. A first WLAN device transmits a sounding packet to a second WLAN device and receives an acknowledgement (ACK) of receiving the sounding packet by the second WLAN device. The first WLAN device uses the received ACK to determine Channel State Information (CSI) for an RF signal path between the first WLAN device and the second WLAN device, aggregates the determined CSI with additional CSI, and uses the aggregated CSI to determine a presence or a motion within the structure.

Abstract: A wireless communication device (WDEV) includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other WDEV (s) and to generate and process signals associated with such communications. The WDEV supports first communications with a first other WDEV and supports second communications with a second other WDEV. The WDEV processes the first communications and the second communications to determine whether the first other WDEV and the second other WDEV are substantially co-located at a physical location. When not co-located, the WDEV processes the first communications and the second communications based on at least one of a ranging or a location protocol to determine location information of the WDEV. Alternatively, when co-located, the WDEV stores information that indicates co-location of the first other WDEV and the second other WDEV.

Abstract: A communications system distributes code word pairs within the audio of a television or radio program or the like. Each pair of code words includes an ID code word that is the same for a given program and a synchronization code word that is unique within the program. A portable user device is able to synchronize itself to the program using the embedded synchronization code words.

Abstract: A wireless communication device (e.g., generally, a device) includes a communication interface and a processor configured to support communications with one or more other devices. In an example of operation, the device supports first communications based on a first communication protocol with a first network coordinator device and identifies a second network coordinator device that operates based on a second communication protocol when supporting those first communications. The device also determines one or more operational parameters associated with the second network coordinator device. When one or more conditions is/are appropriate, the device interworks the first communications and second communications based on the second communication protocol with the second network coordinator device.
