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.

Motion detection using wireless local area networks

A wireless device configured as a group owner determines whether all client devices paired with the group owner are currently associated with the group owner. If all paired client devices are currently associated with the group owner, the group owner enters a first mode in which the group owner is in an active mode (powered up to communicate) during a first portion of a beacon interval and is in a low power mode (in which no communication occurs) during a second portion of the beacon interval. If not all paired client devices are currently associated with the group owner, the group owner enters a second mode in which the group owner is in the active state during the first portion and at least part of the second portion of the beacon interval. The group owner and client devices are configured to operate as master and slave.

Multi-modal wireless connection management

Overhead associated with packet communication is reduced by combining or eliminating one or more fields of a packet. In some implementations, a reduction in overhead associated with packets employing security (e.g., IEEE 802.11ah packets) can be achieved by reducing overhead associated with verification-related fields. For example, a packet can include a merged frame check sequence (FCS) and an integrity check value (ICV). In some implementations, an FCS is omitted from a packet.

Reduced overhead for wireless communication

Operations for a WLAN-capable remote control device and a controlled device are disclosed. A first network device (e.g., remote control) may receive a user input for controlling operation of a second network device (e.g., controlled device) of a communication network. The first network device may transition to an active operating state in response to receiving the user input. The first network device may transmit the first user input to the second network device. The first network device may exit the active operating state in response to successfully transmitting the first user input to the second network device.

WLAN-capable remote control device

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may comprise a transceiver configured to transmit uplink frames and receive downlink frames in a first transaction slot of a super-frame. The one or more of the uplink frames and the downlink frames are associated with over-allocated network allocation vectors that reserve a transmission time which exceeds a time required to transmit acknowledgements of the one or more downlink frames or receive acknowledgement of the one or more uplink frames, respectively. The apparatus may comprise a processing system configured to cause the transceiver to transmit a first uplink frame to the access point with a first over-allocated NAV, to establish a start-time for the super-frame and to extract data from two or more downlink frames in a burst received from the access point.

Low latency 802.11 media access

An access point in a wireless communication system can be configured to include multiple virtual LANS (VLANs) based on security levels, thereby allowing secure traffic to be isolated from insecure traffic. Configuring the access point can include assigning a security level to each VLAN and setting a security association for each station associated with the access point. Based on this security association, each station can be assigned to an appropriate VLAN.

Method for organizing virtual networks while optimizing security

A method for encrypted communications between a first transceiver and a second transceiver is provided. The method includes sending from a first transceiver to a second transceiver a request to initiate derivation of a new encryption key. The request to initiate a new encryption key derivation includes an exchange threshold indicative of when the new encryption key is to be used to encrypt communication packets.
