Abstract
In this paper we discuss the results of the experiment conducted in Poznan, Poland, where the performance of CBRS spectrum sharing model in 3.6–3.8 GHz band has been verified. Three-tier model has been tested, where the highest priority has been assigned to the fixed WiMAX users, whose transmit parameters cannot be modified. Second tier of users was constituted by the peer-to-peer microwave line, whereas the third tier of lowest priority covered the low-power cognitive small-cells. The whole system has been managed by the dedicated remote database located in Finland. Experiments have been carried out in the laboratory, where mainly the functionality of the management of the third tier user has been tested, while protecting the users assigned to two higher tiers.
