Abstract: Technologies for updating a processing device, where a first device image is stored in a first (non-volatile) memory. When a new second device image is received via a communication interface, a first boot of the device is performed and a boot loader performs security processing on the second device image. Once security processing has passed, the second device image is set as a trial image and executed. The executed image is monitored to determine if predetermined operational parameters in the device are met. If the parameters are met, the second device image is set as a current image and the first device image is deactivated. A second boot is performed to make the new image operational for the device and the anti-rollback version one-time programmable fuses are blown. If the parameters are not met, the device revers to the first device image.

Abstract: A power save unit of a first network device determines a sleep duration associated with a sleep mode of a low-power network device based on an exchange of information between the first network device and the low-power network device of a communication network. The power save unit determines whether the low-power network device is in the sleep mode. In response to determining that the low-power network device is in the sleep mode, the power save unit redirects network packets destined to the low-power network device to the first network device. The first network device stores the redirected network packets and notifies the low-power network device that the first network device has stored the redirected network packets.

Abstract: 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.
