Abstract: Described is a system and method for establishing a wireless connection between wireless devices. The method comprises obtaining data of a corresponding computing device. The device conducts wireless communications using a predetermined wireless protocol. The obtained data is processed to generate a wireless address of the device and a first message is transmitted to the device for establishing a wireless connection. The first message is addressed to the wireless address. When a first response message is received from the device, a second message is transmitted to the device. The first response message is generated in response to the first message and includes the wireless address. The second message includes synchronization data. When a second response message is received from the device, the wireless connection is established with the device. The second response message is generated in response to the second message.
Abstract: Methods are provided for processing a packet received by a mesh-enabled access point (MAP). When a first MAP receives a packet it can determine whether the packet is destined for a mesh portal based on the destination address. If so, the first MAP can retrieve an encryption key corresponding to the mesh portal, use the encryption key to encrypt the packet and set a mesh forwarding flag in the packet to indicate that the packet is destined for a mesh portal, and is encrypted with an encryption key corresponding to the mesh portal, and then forward the packet to the next hop MAP towards the a mesh portal. The mesh forwarding flag indicates that the packet is destined for a mesh portal, is encrypted with an encryption key corresponding to the mesh portal, and is to be forwarded to the next hop MAP without performing decryption/re-encryption processing on the packet. When a MAP receives a packet, the first MAP it determines whether a mesh forwarding flag is set in the packet.
Abstract: Apparatus and methods are provided for locating a mobile device in a sleep mode. A method comprises transmitting a beacon signal configured to initiate transmission of a response signal from a mobile device in a sleep mode. The mobile device is associated with a first wireless access device on a first communication channel. The method further comprises receiving the response signal from the mobile device on the first communication channel and determining the physical location of the mobile device based on the response signal.
Abstract: A system is configured to scan for APs on DFS channels while maintaining VOIP traffic employing both passive and active scans. During passive scan mode, the APs are configured to listen only. During active scan mode, the STA sends a probe request, and the AP(s) send(s) probe responses. During power save mode, the STA tells the associated AP that it will be turning “off” to save power. The STA is then required to listen to beacons for traffic notifications. The power save mode enables the STA to move to other channels during periods in which the AP “thinks” it is asleep. An 802.11 “in-use” list is used to facilitate scanning.
Abstract: A remediation system employs local and autonomous conditions within the mobile unit itself. A method for performing remediation for a plurality of mobile units generally includes determining a first set of remediations, wherein each remediation includes a condition for determining whether a remediation is necessary for one of the mobile units, and an action for addressing the condition. The system may determine a second set of remediations, and providing the second set of remediations to the mobile units.

Abstract: A method of handling a discontinuation of service from a wireless access device is provided. The first wireless access device has a first basic service set identifier and communicates with a plurality of mobile units using a first channel. The method comprises transmitting a first service notice with a second wireless access device using the first channel, wherein the first service notice containing information instructing the first plurality of mobile units to transfer to a second channel for service, and providing service to the first plurality of mobile units using the second channel.
Abstract: A self-assignment method for assigning detector and working devices among a plurality of access devices in a wireless network begins by performing wireless data collection with the access devices during an automated calibration period. During this time, each access device receives beacons from one or more other transmitting access devices. The method records radio frequency (RF) data associated with beacons received during the wireless data collection, and thereafter automatically designates at least one of the access devices as a detector device, based upon the recorded RF data.
Abstract: A multicamera imaging-based bar code reader 10 for imaging a target bar code 30 on a target object 32 features: a housing 20 supporting a plurality of transparent windows H, V and defining an interior region, an imaging system including a plurality of camera assemblies C1-C3 coupled to an image processing system, each camera assembly of the plurality of camera assemblies being positioned within the housing interior. Each camera assembly includes a sensor array. Light reflecting fold mirrors split light from a given camera assembly into portions that are directed out of the housing to different fields of view. Light bounces from a target in a camera field of view back along said light path to the image capture sensor array.

Abstract: Methods and systems for automatically updating contact information or executing other commands via a messaging system can automatically associate a command tag with a message. The command tag can, for example, have a value indicating that the message contains contact information, or have another value corresponding to a command. Based on the value of the command tag, the message receiving component can automatically extract the contact information and apply it to a contact database, or can execute the command.
Abstract: A parasitic dipole assisted WLAN antenna for creating a second resonance in the A band and providing greater bandwidth usage to a mobile computing or communication device. A secondary B/G band monopole antenna is connected to the A band antenna at the point of maximum impedance of the A band providing minimal interference between the two bands. The dipole structure antennas are connected at the A band loop antenna feed pin and ground pin.

Abstract: A self-configuration method for access devices in a wireless network begins by performing wireless data collection with the access devices during an automated calibration period. During this time, each access device receives beacons from one or more transmitting access devices, the beacons being transmitted and received using a plurality of different channels available to the wireless network. The method records radio frequency (RF) data associated with the received beacons, and processes the RF data to select, from the plurality of different channels, a respective channel for each of the access devices. In addition, the RF data is processed to adjust transmit power levels for the access devices. The selected channels and adjusted transmit power levels are then used as configuration settings for the access devices.
