Abstract:
In a described example, an integrated circuit includes an input coupled to receive a plurality of beacon frames, the beacon frames include an indication of data transmissions available for a device that includes the integrated circuit. The integrated circuit also includes a controller configured to compare the plurality of beacon frames to determine a plurality of bytes prior to the indication of data transmission available that is present in each of the plurality of beacon frames and is configured to provide a signal indicating a low power mode in which the device does not receive transmissions and to provide a signal indicating a wake mode at a selected time before transmission of the plurality of bytes in a subsequent beacon transmission.
Abstract:
A controller is arranged to: receive a first decoded beacon frame which includes a first indication of a first data transmission; receive a second decoded beacon frame which includes a second indication of a second data transmission; compare the first and second decoded beacon frames to determine common bytes in the first and second decoded beacon frames; determine an expected time of receiving the common bytes in a third beacon frame; control a device to enter into a low power mode; and control the device to wake up from the low power mode at a time to receive and decode at least a portion of the third beacon frame, in which the time to wake up is based on the expected time to receive the common bytes instead of based on an expected time to receive a preamble at a start of the third beacon frame.
Abstract:
A Wi-Fi device includes a controller coupled to a writeable memory implementing a MAC and PHY layer and to a transceiver. Connection data stored in the writeable memory includes Wi-Fi connection parameters including ≥1 router MAC level information or a most recently utilized (MRU) channel used, and IP addresses including ≥1 of an IP address of the Wi-Fi device, IP address of the MRU router, an IP address of a MRU target server, and an IP address of a network connected device. An accelerated reconnecting to a Wi-Fi network algorithm is implemented by the processor is for starting from being in a network disconnected state, establishing current connection parameters for a current Wi-Fi network connection using the Wi-Fi connection parameters for at least one MAC layer parameter for the MAC layer.

Abstract:
A system and method is disclosed that enables a peripheral or slave device to seamlessly transition in and out of sleep state while remaining completely transparent to host software. When the device is in a sleep mode and incoming data is detected, the device begins a wake-up procedure and data is routed to a first, transitional memory. The size of the transitional memory is selected such that it is capable of buffering data received during time required for the system memory to stabilize from wake-up. Once a second, extended memory is stabilized, the data is buffered from the transitional memory to the extended memory. The device resumes normal operation when its processor has initialized and can read data from the extended memory.
Abstract:
A wireless universal serial bus (USB) system that includes a wireless USB host, a first wireless USB device, and a second wireless USB device. The wireless USB host is configured to wirelessly transmit a beacon over a wireless USB network based on a wireless USB protocol. The first and second wireless USB devices are configured to exchange wireless packets with the wireless USB host. The beacon designates the wireless USB network address access times for the first and second wireless USB devices.

Abstract:
Systems and methods for enabling proximity operations with long-range wireless communication interfaces are described. In an illustrative, non-limiting embodiment, a method may include transmitting a plurality of data packets using a WiFi interface of a first device, where each data packet has a signal strength following a predetermined pattern; and receiving an indication, via the WiFi interface, of whether the predetermined pattern has been identified by a second device.
Abstract:
