Wireless sensor network with power management and with deterministic control from an access point |
摘要 |
Providing wireless communication between an access point and a wireless device includes the wireless device operating in a first reduced power mode for a first period of time, where the wireless device does not receive communications while operating in the first reduced power mode and includes the wireless device operating in a full power mode for a second period of time, where the wireless device transitions back into the first reduced power mode in response to there being no communication from the access point to the wireless device during the second period of time. The wireless device may be a wireless sensor. In response to the access point directing the wireless sensor to collect data at a particular collection time, the wireless sensor may enter the first reduced power mode for a time prior to the collection time. |
