摘要： An RFID system provides opportunistic locationing of RFID tags and associated assets in environments where multiple tags are read from multiple readers. A radio frequency identification (RFID) system includes one or more location triggers and a first RFID reader coupled to the network having a first antenna associated therewith. The first reader is configured to read a first set of tag IDs from a first set of RFID tags within a first range of the first antenna. A second RFID reader is coupled to the network and has a second antenna associated therewith. The second RFID reader is configured to read a second set of tag IDs from a second set of RFID tags within a second range of the second antenna. An RF switch is coupled to the network and is configured to receive the first set of tag IDs and the second set of tag IDs from the first RFID reader and the second RFID reader. The RF switch is configured to reconcile the location of an asset having a particular tag ID when the particular tag ID is an element of both the first set of tag IDs and the second set of tag IDs.

摘要： 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, issuing the 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 said comparing step. The metafile language has a relatively simple vocabulary and syntax, and is thus easy to learn and implement.

摘要： Wireless switch licenses are assigned on a cluster basis rather than being limited to individual switches. A switch cluster is made up of two or more wireless switches that each having an assigned number of licenses. Each of the wireless switches is configured to establish the switch cluster with the other wireless switches, and to verify the identity of each other wireless switch in the switch cluster during operation. License restrictions are enforced based upon a total number of licenses for the switch cluster so that the sum of the numbers of licenses assigned to the wireless switches in the cluster are available for use even if one or more of the other wireless switches in the cluster become unavailable.

摘要： A wireless data communication system suitable for use as a radio frequency (RF) locationing or presence detection system includes at least one wireless access device and at least one active RF tag corresponding to an item or asset of interest. The wireless access device is configured to transmit a locale message that conveys location-specific data corresponding to a geographic operating region of the wireless access device. The active RF tag receives the locale message, processes the location-specific data conveyed in the locale message, and configures itself in accordance with the location-specific data to support operation using a selected wireless data communication scheme. The selected scheme is compliant with the operating requirements of the geographic operating region in which the active RF tag resides.
