1. A method of monitoring spectrum usage in a cognitive radio system comprising:
- distributed monitoring of spectrum usage using at least one first monitoring apparatus and at least one second monitoring apparatus;
the at least one first monitoring apparatus having a level of monitoring precision higher than a level of monitoring precision of said at least one second monitoring apparatus; and
transferring information data on the spectrum usage collected by one of the at least one first and at least one second monitoring apparatuses to another one of the at least one first and at least one second monitoring apparatuses for pre-processing.

Abstract
Spectrum usage in a radio cognitive transmission system may be monitored in a distributed manner in space and time through a first set of monitoring apparatuses and a second set of monitoring apparatuses. The first set of monitoring apparatuses may be associated to apparatuses, such as base stations, having a monitoring precision level, for example, linked to the spectrum sampling frequency, greater with respect to the monitoring precision of the monitoring apparatus of the second set. The later may be suitable to be represented by a low-cost “sniffer” associated to consumer electronics devices.
