The increasing proliferation and concentration of wireless technology in public and private spaces also increases the prospect of interference and performance degradation. In many circumstances, monitoring this complex signal environment is crucial to ensure the viability of essential services, such as emergency response units that could otherwise find their command and control systems impaired by a cluttered spectrum.
Tracking all of the traffic on this spectrum calls for quality measurements, analysis of interference, identification of signal sources, interception of those signals, band clearing and regulatory enforcement. Readily available components - including an antenna and wideband receiver - can begin these tasks, providing analogue input to a converter that generates digital output for more detailed processing.
Software then takes over the task of sorting out how the spectrum is being used, and what the implications of that use might be. The faster it can do so, the sooner potential problems can be flagged and addressed, and the lower the risk to everyone who might be affected.
