Abstract
An environmental simulator for use in the testing of wireless devices comprises a base station simulator, a signal manipulator, a switch and an antenna array. The environmental simulator is configured to couple wireless signals to and from a device under test in order to test the performance of the device over a variety of real world operating conditions.
Claims11
An environmental simulator for use in the testing of wireless devices, comprising:
- a base station simulator configured to create forward link signaling intended for a wireless remote unit;
- a signal manipulator coupled to said base station simulator and configured to impose a measure of manipulation of said forward link signaling in order to produce one or more manipulated forward link signals;
- a switch having a plurality of input ports coupled to said one or more manipulated forward link signals and having a series of output ports, wherein said switch is configured to programmably couple one or more input port to one or more output port;
- an antenna array comprising a plurality of antennas, each antenna coupled to at least one of said series of output ports, said antenna array configured to couple wireless signals to a wireless remote unit;
- and
- a controller coupled to said signal manipulator and said switch, said controller controlling said measure of manipulation imposed by said signal manipulator and said programmable coupling of said switch.
3 more elements
A method of wireless remote unit testing, comprising the steps of:
- generatrng wireless for ward link signaling;
- manipulating said forward link signal link to generate specified test conditions thereby creating one or manipulated signals;
- coupling said one or more manipulated signals to a set of selected antennas within an array of antennas;
- and
- collecting a set of test data from a wireless device under test wherein said device under test is wirelessly coupled to said antenna array and is capable of separately receiving multipath signals.
