  • Patent number: 7440741
    Abstract: A method and system for over-the-air testing of a radio transreceiver is described. The radio transreceiver is placed in an enclosure box that is shielded to prevent leakage of RF energy. A nest assembly holds in place the radio transreceiver during testing to provide repeatable results with different radios. The testing assembly allows high volume characterization of the radio transreceiver performance in an environment rich with interfering RF signals.

  • Publication number: 20080100329
    Abstract: Methods, systems, and apparatuses for ways of testing tags are provided. In an aspect of the present invention, an antenna is mounted in a cavity of a surface. The antenna transmits a test signal, such as a radio frequency (RF) test signal, to the antenna of an adjacent tag, to test the adjacent tag. In aspects, multiple cavities having antennas may be arranged in various ways in the surface, such as in a “checkerboard pattern” (e.g., diagonally positioned from each other), to test multiple tags in a web of tags simultaneously. In another aspect, tags that are not being tested may be held at an electrical voltage, such as a ground voltage, to disable the tags from responding to the test signals of other tags. For example, in an aspect, a vacuum system may be used to hold tags in a web of tags to the surface to hold antennas of the tags at the electrical voltage.

  • Publication number: 20070139057
    Abstract: Methods, systems, and apparatuses for testing radio frequency identification (RFID) tags are described. The tags are tested using a direct connection scheme, where a testing apparatus makes direct contact with a portion of a tag in order to perform a test on the tag. For example, the testing apparatus may read data from the tag to verify operation. Any number of tags may be tested at a time, including one tag at a time, or multiple tags in parallel.
