In this paper it is envisaged that Cognitive Radios (CRs) consult a supporting network infrastructure for per-mission to transmit. The network server either grants or rejects these requests by estimating, from the CRs geo-location and antenna features, the likely impact its transmission would have on incumbents and other CR devices. This decision would be based on a real-time radio environment map which would be kept up to date with readings from CRs, sensors and dynamic radio propagation prediction.
