Abstract: In an embodiment of the present invention, a wide-band spectrum analyzer system uses a combination of components to achieve wide-band spectrum analysis to conduct a spectrum survey to provide an optimum selected frequency for communication. A certain frequency within a band may be identified for a mobile device, such as a cellular telephone or satellite radio system, to receive or transmit communications signals. The spectrum survey may provide a mobile network a number of frequency options. The system for conducting the spectrum survey may be stationary or mobile and may be implemented in hardware, software or a combination of hardware and software.
