Abstract: A spectrum access system (SAS) includes a transceiver configured to receive a registration request from a first base station in response to the first base station being installed. The SAS also includes a processor configured to allocate a channel in a shared spectrum and a transmission power to the first base station. The transceiver is configured to transmit a test grant authorizing the first base station to transmit on the channel at the transmission power for a predetermined time interval. The test grant is converted to a suspended grant following the predetermined time interval. In some cases, the transceiver is configured to receive the registration request from the first base station in response to the first base station being installed in a protection area.
