摘要:
An asset tracking system includes a station, transmitting points, and an asset tag. The asset tag can be used for communicating with the transmitting points to form a mesh network. The station receives data associated with signal strengths between transmitting points and asset tag. The station analyzes the data associated with a number of the transmitting points and determines the location of the asset tag.
摘要:
The system comprises a plurality of reference tags affixed to reference locations in a coverage area and configured to form a wireless mesh network. The system also includes a call tag configured to communicate with the plurality of reference tags and to collect data regarding the communication with the plurality of reference tags. The call tag is configured to send a first signal in response to an event. A positioning system is coupled to the wireless mesh network and configured to receive the first signal and the data collected by the call tag. The positioning system is further configured to process the data collected by the call tag to determine the call tag location with respect to the plurality of reference tags. A portable electronic device is configured to communicate with the wireless mesh network and configured to receive call tag location from the positioning system.
摘要:
A system can be for use with a number of reference tags disposed at respective reference locations in a coverage area. The reference tags can be configured to form a wireless mesh network. A system can include a first tag configured to communicate with the reference tags. The first tag can operate in a sleep mode and includes a motion sensor. The first tag is woken out of the sleep mode on a first periodic basis to communicate with the reference tags. The first tag is woken out of the sleep mode at a second periodic basis in response to motion signal from the motion sensor. The second periodic basis is more frequent than the first periodic basis. The system can also include a positioning system configured to receive data related to the communication between the first tag and the reference tags. The positioning system can be configured to process the data to determine a location of the first tag.
摘要:
A system includes a tag associated with an item wirelessly transmitting data; a network device receiving the data and determining a location of the item; and a mobile unit receiving the location of the item from the network device. The mobile unit further receives the data from the tag and outputs a description of the item based on the data.

A system for assessing the state of an RF network includes a plurality of wireless devices coupled to the network and having one or more associated antennae, the wireless devices configured to process data received from a plurality of RF elements within range of the antennae. An RF switch is coupled to the network and configured to receive the data and transmit the data over the network. A first memory within the RF switch is configured to store a system state comprising a plurality of performance indicators, wherein each of the performance indicators is associated with an operational characteristic of one or more of the plurality of wireless devices. A second memory within the RF switch is configured to store a plurality of labeled data entries, the labeled data entries each including the system state and a user-entered identifier, wherein the user-entered identifier includes information related to the time at which the system state was selected. A display coupled to the network is configured to display a comparison of the system states.
摘要:
A handheld device (e.g., an RFID reader, mobile computer, or the like) is configured to periodically scan its environment for the presence of RFID tags, determine whether any of the RFID tags within range include a valid security code, then disable operation (e.g., by preventing access to stored data) when it is determined that there are no RFID tags with a valid security code within the operational range. The RFID tags may be placed strategically at secure locations within the environment, such as within other network devices (access ports, switches, etc.).

A method for automated testing of a device (e.g., a router, switch, mobile terminal, barcode reader, or the like) includes creating a metafile, establishing a network connection to the device, parsing the metafile to determine a device command and an expected result, apply a terminology substitution process to the device command based on a terminology block associated with the device, thereby creating a modified device command; issuing the modified device command to the command line interface of the device via the network connection; receiving a response from the command line interface of the device via the network connection; comparing the response to the expected result, then logging, to a test summary file, a test result based on the comparing step. The metafile language has a relatively simple vocabulary and syntax, and is thus easy to learn and implement.
摘要:
A graphical management system includes a web browser application communicatively coupled to a web service and a graphical management module over a network and a plurality of wireless devices (e.g., RFID readers, access ports, etc.) coupled to the network and having one or more associated antennae. The wireless devices are configured to process data received from a plurality of RF elements (mobile units, 802.11 devices, RF tags, etc.) within range of the antennae. An RF switch coupled to the network is configured to receive the data and transmit the data to the graphical management module, which provides to the web service graphical information relating to the state of the RF elements (e.g., location information, heat maps, intrusion detection, self-healing status, etc.)
摘要:
Wireless switches in a cluster are managed by providing a configuration server for storing common configuration files and a DHCP server for storing cluster-specific configuration files corresponding to each cluster. A method for configuring the wireless switches then includes requesting, from the DHCP server, an IP address for the wireless switch; receiving, from the DHCP server, the IP address and the cluster-specific configuration file; receiving, from the configuration server, the common configuration file; and executing, at the wireless switch, the cluster-specific configuration file and the common configuration file.
摘要:
A wireless data communication system includes an access port configured to wirelessly communicate with a plurality of mobile units within multiple basic service sets (BSS), and a wireless switch having multiple predefined wireless local area networks (WLANs). The wireless switch is configured to automatically map the WLANs to the basic service sets and transmit to the access port a configuration template depending upon the type of access port. In one embodiment, there are n basic service sets, each having a corresponding basic service set identifier (BSSID), and m WLANs, each having a corresponding WLAN index, wherein the m WLAN indices are uniformly mapped to the n BSSIDs such that each BSSID has substantially the same number of WLAN indices mapped thereto. In a particular embodiment, there are n=4 BSSIDs per access port and m=16 pre-mapped WLANs. In this way, the wireless switch and respective access ports can be set-up in a simplified manner, in much the same way that set-up is performed with traditional access points.
