Abstract
Methods and systems for formatting and transmitting a wake-up signal for electronic devices having a wake-up receiver circuit. A low-power wake-up signal is transmitted, the wake-up signal comprising a wake-up frame including a legacy preamble decodable by legacy electronic devices and a wake-up packet decodable by the wake-up receiver circuit in a non-legacy electronic device. The legacy preamble includes information detectable by at least one of the legacy electronic devices indicating that the wake-up frame is not a valid frame for the at least one legacy electronic device, such as where the legacy electronic device is a IEEE 802.11n/ac/ax device.
Claims20
A method comprising:
- transmitting a low-power wake-up signal, the wake-up signal comprising a wake-up frame including a legacy preamble decodable by legacy electronic devices (EDs) and a wake-up packet decodable by a wake-up receiver circuit in a non-legacy ED;
- wherein the legacy preamble includes information detectable by at least one of the legacy EDs indicating that the wake-up frame is not a valid frame for the at least one legacy ED.
An access point comprising a processor configured to execute computer-readable instructions to cause the access point to:
- transmit a low-power wake-up signal, the wake-up signal comprising a wake-up frame including a legacy preamble decodable by legacy electronic devices (EDs) and a wake-up packet decodable by a wake-up receiver circuit in a non-legacy ED;
- wherein the legacy preamble includes information detectable by at least one of the legacy EDs indicating that the wake-up frame is not a valid frame for the at least one legacy ED.
A method comprising:
- receiving a wake-up signal, the wake-up signal comprising a wake-up frame including a legacy preamble decodable by a legacy electronic device (ED) and a wake-up packet decodable by a wake-up receiver circuit of a non-legacy ED;
- detecting information in the legacy preamble indicating that the wake-up frame is not a valid frame for the legacy ED.
