The usual approach for the search of a stochastic background of gravitational waves relies on correlating data from different detectors that share common sensitivity bands. This method leverages the overlapping frequency ranges to enhance the signal-to-noise ratio and improve detection confidence. However, here an alternative approach will be explored: detecting and characterizing a stochastic background using a network of detectors with non-overlapping sensitivity bands, such as the Einstein Telescope (ET) and the Laser Interferometer Space Antenna (LISA). We will delve into the theoretical and practical conditions under which this method is viable, including the mathematical framework for cross-correlating data from detectors operating in different frequency ranges. The role of the non-Gaussianity of the stochastic background will be a focal point, as non-Gaussian features can provide additional information about the sources and the nature of the background. We will discuss how non-Gaussian statistics can be used to distinguish between different types of stochastic backgrounds, such as those arising from astrophysical sources like binary black hole mergers and those from cosmological sources like primordial gravitational waves.
