Certain aspects of the present disclosure provide apparatus and techniques for configuring memory in an effort to reduce power consumption. For example, certain aspects of the present disclosure may provide an apparatus having a processing system configured to determine an operating mode of an application executing on the processing system. The operating mode may be one of a plurality of operating modes of the application, and each operating mode of the plurality of operating modes may correspond to a different configuration of memory. In certain aspects, the configurations of memory may correspond to different portions of memory that are active or inactive. In certain aspects, the apparatus may also include a memory control module configured to configure the memory based on the determined operating mode of the application.

Configurable low memory modes for reduced power consumption

A wireless device configured as a group owner determines whether all client devices paired with the group owner are currently associated with the group owner. If all paired client devices are currently associated with the group owner, the group owner enters a first mode in which the group owner is in an active mode (powered up to communicate) during a first portion of a beacon interval and is in a low power mode (in which no communication occurs) during a second portion of the beacon interval. If not all paired client devices are currently associated with the group owner, the group owner enters a second mode in which the group owner is in the active state during the first portion and at least part of the second portion of the beacon interval. The group owner and client devices are configured to operate as master and slave.

Multi-modal wireless connection management

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.

Power save mechanism for low-power network devices

Systems, methods, and devices for address format detection are described herein. In one aspect, a method of detecting whether an addressing format is supported by an access point on a wireless network is disclosed. The method includes transmitting a request to an access point using an addressing format including a source address field and a separate transmitter address field. In some aspects, the request may be an address resolution protocol (ARP) request or an Internet Control Message Protocol (ICMP) ping request. The request includes the source address field set to a first address and the transmitter address field set to a second address; monitoring transmissions of the access point to determine whether the access point transmits a response to the request that includes a destination address equal to the first address; and determining whether the access point supports the addressing format based on the monitoring.

Systems, apparatus, and methods for address format detection

A method of automatically configuring a wireless device includes performing service discovery by the wireless device to identify a programming module and sending to the programming module a probe request including a first device public key. The method includes receiving from the programming module a probe response including an indication of a match between the first device public key and a second device public key.

Automatic configuration of a wireless device

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.

Low latency 802.11 media access

A method of automatically configuring a wireless device includes receiving programming credentials from a server at a programming module and authenticating the wireless device based on the programming credentials. The method includes programming the wireless device with access credentials of an access point of a network to enable the wireless device to communicate, via the access point, with one or more devices outside of the network.

A method and system to transmit code to a System on Chip (SOC) from a host processor using a host-side driver is provided herein. The SOC and host processor are coupled by a bus. The host driver receives an overlay from an application layer and stores the overlay. The host driver receives an IOCTL to be transmitted to the SOC. The host driver determines whether an input/output control (IOCTL) value of the IOCTL to be transmitted to the SOC corresponds to an IOCTL value in one of the stored overlays. The host driver transmits an overlay to the SOC if the IOCTL value of the IOCTL to be transmitted is equal to at least one IOCTL value in the overlay. The host driver then transmits the IOCTL to the SOC.

Method and system to transmit code to a system on a chip (SOC)

A method and system for advanced media access control delegated from a host device, such as a WiFi device, to a smart wireless communications module. In an embodiment, the host signals to the wireless module a list of one or more preferred networks. The wireless module offloads from the host the processing required to scan for the preferred network(s), as well as possibly other management tasks. The wireless communications module may automatically reassign the network connection from an existing network to a preferred network, or may report to the host when a preferred network is discovered. In either case, the wireless communications module may monitor the wireless environment, and scan for preferred networks, in parallel with maintaining an existing connection. The method and system allows rapid adaptation to a changing network environment, and enables lower system power consumption by distributing management functions between the host and the lower-powered wireless communications module.
