Spectrum Analyzer on SOHO Router

The wireless WAN feature on the Surf Soho routers has been extremely important to our deployments. As it allows up to scan for network remotely that could be broadcasting on the same frequency as the SOHO router. I was wondering if it would be possible to give the SOHO routers the ability to have Spectrum Analyzer in the router to be able to scan for devices that might not be broadcasting a SSID.
