Wireless networks providing voice, data, and video operate in an increasingly crowded spectral environment. Commercial wireless networks are increasingly devoid of guard bands between channels or adjacent services, making it essential that their systems and those of their neighbors are extremely linear and not create adjacent-channel distortion. Monitoring of their continuous and non-contiguous channels requires capturing signals over wide frequency ranges and potentially long periods and analyzing the results.
X-COM Systems Solutions for Wireless Communications
To address these issues, X-COM's IQC5000A Spectrum Capture and Playback System and Spectro-X Signal Analysis Toolkit software allow wireless carriers and military communications centers to capture on-air signal environments, detect anomalous conditions, identify their type, and create files containing the problems. These can be used to either bring their own equipment into compliance or use them as unimpeachable evidence when confronting the offending operator. The IQC5000A's dual channel capture capabilities can also be used to test and diagnose problems with MIMO systems that are increasingly being relied upon in wireless communications systems.
After being analyzed by Spectro-X software (and potentially edited using RF Editor, Graphical RF Signal Editor software) captured signals can also be played back in the lab or field using the IQC5000A's analog I&Q or RF outputs. If multiple channels of phase adjustable playback are needed (perhaps for MIMO systems) one of X-COM's vector signal generators could be used instead.
