Embodiment Construction

[0033] Referring to FIG. 1 , in one embodiment, a system 10 for determining radiated performance of a wireless device 12 includes a controller system 14 for generating control signals 16 for transmitting radio wave signals 18 to the wireless device 12 . The wireless device 12 is located within the test chamber 20 at a location 22 selected from a plurality of predetermined locations associated with a predetermined radiation performance test 24 run by the controller system 14 . The control signal 16 includes a positioning component 26 that defines the physical coordinates of the selected location 22, thereby specifying the movement of the positioning system 28 to which the wireless device 12 is mounted. Furthermore, the control signal 16 includes a corresponding signaling component 30 which defines the radio wave signal 18 and thus specifies the transmission of a radio signal system 32 . In one embodiment, for example, radio signal system 32 emulates a base station in a cellular...

Abstract

Systems, methods, apparatus, processors and computer-readable media include a radiated testing module that executes a predetermined radiated performance test on a wireless device. The test dictates various performance-related parameters to measure and log at each of a plurality of predetermined positions. Further, the wireless device receives synchronization information operable to enable synchronization between the logged measurements and each of the positions. The synchronized log allows the wireless device, or another apparatus, to determine a radiated performance characteristic based on apredetermined analysis protocol. Further, the described embodiments allow for the determination of several radiated performance characteristics in a single test, using a single, unaltered wireless device.

Description

[0001] Priority claim based on 35 U.S.C. §119 [0002] This application for patent claims the benefit of priority from Provisional Application No. 60 / 621,883, filed October 25, 2004, entitled "ANTENNA CORRELATION FROM MEASUREDCOMPLEX RADIATION PATTERNS," and Provisional Application No. 60 / 660,918, entitled "METHOD AND APPARATUSFOR PERFORMING RADIATED ANTENNA TESTS," both of which are assigned to the assignee of this application and are hereby incorporated by reference into this application. Background technique [0003] The described embodiments relate to wireless communication devices, and more particularly to systems, methods, apparatus, processors, and computer-readable media for determining radiation performance of antenna systems associated with wireless devices. [0004] Wireless devices utilize radio waves to provide long-distance communication without the physical constraints of wire-based systems. A wireless device transmits and receives information via radio waves t...
