Abstract: A system for reducing power consumption in a wireless network includes a station (e.g., Wi-Fi sensor) and an access point in wireless communication with the station. The station has at least a low-power sleep mode and an active mode. The system can be configured to assign a static Internet Protocol (IP) address to the station and disable re-negotiation of an encryption key while the station is in sleep mode. The system can further be configured to force the station to communicate via 802.11g and to transmit data to a proxy service while in active mode before returning to sleep mode upon receiving a response from the proxy service. Further, an association timeout period associated with the station can be configured to be at least twice as long as a wake-up period associated with the station.

Abstract: A device for use in a building management system (BMS) includes a base hardware component that provides communication between the equipment and a first network associated with the BMS. The base hardware component includes a processor and a memory. The device further includes a modular hardware component connected to the base hardware component and a modular software component stored in the memory that recognizes the modular hardware component connected to the base hardware component and provides communication between the equipment and a second network using the modular hardware component. The processor executes a control application to control operation of the equipment based in part on data received from the equipment and data received from at least one of the first network and the second network.
