A system of controlling one or more building automation devices. The system may incorporate communicating over a first network with one or more network connected devices. An access point for the first network may be utilized to facilitate communication among the network connected devices. One or more of the network connected devices may be a low power device that has a first mode and a second mode. The low power device may expend less energy in one of the first mode and the second than in the other of the first mode and the second mode. The system may allow network devices connected to the first network to receive details about the low power device while the low power device is operating with the first mode and the second mode.

System for communication with devices on a network to minimize power consumption

A system includes first and second access points. Each access point includes one or more 802.11 wireless radios configured to communicate with a wireless node. The first and second access points are both configured to wirelessly receive first data from the wireless node at substantially a same time and forward the first data. The first and second access points are also both configured to receive second data for the wireless node. The first access point is configured to wirelessly transmit the second data to the wireless node, and the second access point is configured to refrain from transmitting the second data to the wireless node while the first access point is operating properly.

Shadow access point for hierarchical tree network using 802.11 infrastructure nodes in fire detection systems and other systems

Methods, devices, and systems for managing a wireless mesh network are described herein. One method includes monitoring an outgoing data queue length of a node of a wireless network, determining that the outgoing data queue length exceeds a particular threshold, reducing a video quality associated with the outgoing data queue, and sending a notification to an additional node of the wireless network to reduce a video quality associated with an outgoing data queue of the additional node.

Managing a wireless mesh network

A network includes an access point Wi-Fi Direct (AP WFD) device. The AP WFD device includes access point (AP) functionality. A plurality of client WiFi Direct (WFD) devices is coupled to the AP WFD device. The client WFD devices include client functionality. The AP WFD device is configured to synchronize the client WFD devices and to stream multimedia data to the client WFD devices.

Multimedia streaming over multiple hops in WiFi mesh network

Devices, methods, and systems are described herein. One device includes a speaker component to broadcast a message, a microphone component to detect a sound, an IP component to receive the message using a communication path, and a computing component to determine a source of the detected sound.

Internet protocol addressable public address devices and systems

A method including running a local low frequency clock in a node in a network during a battery conserving sleep mode, waking from the sleep mode at a time boundary determined by the low frequency clock, updating a representation of a master time based on a calculation and the time boundary, advancing the representation of master time based on a local high frequency clock while the node is awake, receiving a time synchronization signal from a node in the network, updating the calculation based on a difference between the representation of master time and a time provided in the time synchronization signal, setting a new time boundary, and returning to the sleep mode.

Wireless sensor time synchronization

A system includes multiple nodes, where each node includes one or more 802.11 wireless radios. The nodes are arranged in a hierarchical tree structure in which one or more nodes residing in one level of the tree structure are configured to communicate with one or more nodes residing in another level of the tree structure to propagate information in the tree structure. At least a first of the nodes is configured to operate its associated radio(s) in an 802.11 access point mode and in an 802.11 station mode. The first node is configured to relay data to and from one or more nodes in a lower level of the tree structure using the 802.11 access point mode. The first node is further configured to transmit data to and receive data from one or more nodes in a higher level of the tree structure using the 802.11 station mode.
