Claims25
A wireless transceiver test bed for testing a wireless transceiver unit under test (UUT), comprising:
- a virtual wireless channel processor;
- a computer program for the virtual wireless channel processor, the computer program comprising:
- a computer usable medium having computer readable program code modules embodied in said medium for emulating a radio frequency (RF) environment;
- a computer readable first program code module for modeling noise in a wireless environment;
- a computer readable second program code module for modeling interference in a wireless environment;
- a computer readable third program code module for modeling the path loss for a wireless signal;
- a computer readable fourth program code module for modeling the presence of multipath transmission;
- a computer readable fifth program code module for modeling a virtual spectrum user (VSU) having selectable transmission parameters and selectable physical characteristics;
- a computer readable sixth program code module for selecting transmission parameters and physical characteristics of the UUT;
- a test instrumentation processor, comprising:
- a first port for receiving test instrumentation signals from the UUT and VSU;
- a second port for receiving RF environment emulation information from said virtual wireless channel;
- a computer program for the test instrumentation processor, the computer program comprising:
- a computer usable medium having computer readable program code modules embodied in said medium for evaluating the performance of the UUT and VSU in the emulated RF environment.
The system of claim 3 wherein the metadata includes at least one of time stamp information, location, frequency, bandwidth and analog to digital conversion parameters.
A method of testing a wireless transceiver unit under test (UUT), comprising the steps of:
- (a) selecting transmission parameters and physical characteristics of a UUT;
- (b) modeling in a processor a virtual spectrum user (VSU) having selectable transmission parameters and selectable physical characteristics;
- a virtual wireless channel processor;
- (c) emulating a radio frequency (RF) environment comprising the steps of:
- (i) modeling noise in a wireless environment;
- (ii) modeling in a processor interference in a wireless environment;
- (iii) modeling in a processor the path loss for a wireless signal;
- (iv) modeling the presence of multipath transmission;
- (d) receiving test instrumentation data from the UUT and VSU;
- and
- (e) evaluating a performance of the UUT and VSU in the emulated RF environment.
