摘要:
A system and method for concurrent WLAN and WPAN wireless modes from a single device is presented. A client uses a Wi-Fi device's infrastructure mode to communicate in a WLAN environment and, during idle WLAN times, uses the Wi-Fi device's adhoc mode to communicate in a WPAN environment. The Wi-Fi device uses a watchdog timer to switch between infrastructure mode and adhoc mode. When the client's Wi-Fi device switches to infrastructure mode, the client's Wi-Fi device uses an infrastructure register and an infrastructure device driver to transfer data over the WLAN environment. Likewise, when the client's Wi-Fi device switches to adhoc mode, the client's Wi-Fi device uses an adhoc register and an adhoc device driver to transfer data over the WLAN environment. The client uses a code shim to act as a virtual device driver at times when either the infrastructure device driver or the adhoc device driver is inactive.

A data processing network configuration includes a server and an access point wired to a network and a mobile system wirelessly connected to the access point. The access point receives and stores a request to retrieve information from the mobile system. The mobile system, when in a powered down state, powers its wireless network adapter periodically to poll the access point to discover the stored request for information. The mobile system responds to discovery of the stored request by retrieving the requested information from nonvolatile storage of the mobile system and transmitting the requested information via the wireless network adapter while otherwise remaining powered down. The information request may be a system management request and the request packet may include a Media Access Control (MAC) address repeated multiple times. The access point stores pending requests in a table having an entry for each associated mobile system.

An apparatus, system and method of verifying an interface address are provided. A communication device is connected to a network. The apparatus, system and method query the communication device for an interface address identifying the communication device to the network. The apparatus, system, and method further receive the interface address from the communication device and identify an invalid interface address. In one embodiment, the interface address is invalid if it is outside of a specified interface address range. The apparatus, system, and method mitigate the invalid interface address. In one embodiment, the apparatus, system, and method mitigate the invalid interface address by deactivating the network.

A method and system is described for remotely managing a battery powered client computer. A data packet, which includes a set of instructions, is sent to the client computer from a managing computer. Included in the data packet is a field indicating how much computing time is needed to execute the set of instructions. If the client computer is operating on battery power, the client computer determines if there is enough battery life remaining to execute the set of instructions. If not, then the set of instructions are disregarded.
摘要:
A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to balance loads by deferring association of new clients and thereby directing clients to associate with alternative access points having improved backbone connectivity. Where the client is unable to find an alternative access point, the client will eventually make a second association request to the access point. The access point, in identifying the second association request of the client, proceeds to associate the client in response to the second association request. Specific time limits can be imposed relative to the second association request.
摘要:
A wireless network client is described which obtains access to the resources of a backbone network provided by a wireless access point. The client is adapted to receive a reassociation request from an access point which is able to detect a degraded condition on the backbone network and inform clients of the degraded condition. Upon detecting the degraded condition, the access point transmits or broadcasts a reassociation request to one or more clients associated with the access point. Information can also be sent identifying the degraded performance of the backbone network and can include other information useful to clients. Once a client has received the reassociation request and/or the informed identifying the degraded performance, the clients seek access to the backbone network through other access points which are not experiencing degraded performance. The seek preferably omits the access point identified as experiencing degraded backbone performance.
摘要:
A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to detect a degraded condition on the backbone network. Upon detecting the degraded condition, the access point transmits or broadcasts a reassociation request to one or more clients associated with the access point. In addition, the rate at which new associations are made is halted or reduced during the degraded backbone condition. In one embodiment, the association rate is reduced by increasing the interval between beacons transmitted by the access point which identify the access to the backbone network.

An apparatus for distance-based network resource discovery includes a storage device storing machine-readable code and a processor executing the machine-readable code. The machine-readable code includes a determination module determining a distance between an information handling device and a network resource capable of communication with the information handling device. The machine readable code also includes a policy module following a discovery policy according to the distance. The discovery policy is associated with discovery of the network resource.

Systems, methods and products directed toward context aware device disconnection are provided herein. One aspect includes obtaining one or more physical measurements of an information handling device connected to one or more external systems, the one or more physical measurements being measured using one or more physical characteristic measurement elements; analyzing the one or more physical measurements using one or more policy settings configured in one or more disconnection policies stored on the information handling device; and initiating one or more disconnection events responsive to the one or more physical measurements matching the one or more policy settings. Other embodiments are described herein.
摘要:
An apparatus and method are presented for a maximum speed criterion for a velocity gesture. The apparatus includes a processor, a memory, a determination module and a transmission module. The determination module determines, through a wireless communication infrastructure mode, an amount of wireless network activity. The transmission module sets a rate of data transmission in a peer to peer mode based on the amount of wireless network activity.
