The first step required by the process of cognition is the intelli- gent observation of the environment that surrounds the actors of such a process. We present the CalRAdio-Based advanced Spec- trum Scanner (CRABSS), an open platform developed to monitor the ISM 2.4-2.499 GHz band and reveal opportunities for a bet- ter utilization of the available spectrum resources. CRABSS is built through a modular approach by integrating the development platform CalRadio 1 with the Unified Link Layer API (ULLA) framework. This solution provides sensing capabilities while pre- serving the 802.11b standard compatibility on the CalRadio 1 plat- form. Moreover, it takes advantage of the ULLA framework to ex- port spectrum occupancy information to prospective cognitive ra- dio manager engines, through a standardized set of sensing APIs.

Abstract
The first step required by the process of cognition is the intelli- gent observation of the environment that surrounds the actors of such a process. We present the CalRAdio-Based advanced Spec- trum Scanner (CRABSS), an open platform developed to monitor the ISM 2.4-2.499 GHz band and reveal opportunities for a bet- ter utilization of the available spectrum resources. CRABSS is built through a modular approach by integrating the development platform CalRadio 1 with the Unified Link Layer API (ULLA) framework. This solution provides sensing capabilities while pre- serving the 802.11b standard compatibility on the CalRadio 1 plat- form. Moreover, it takes advantage of the ULLA framework to ex- port spectrum occupancy information to prospective cognitive ra- dio manager engines, through a standardized set of sensing APIs.
