A wireless base station system includes a phase-locked loop (PLL) and hold-over circuit linked to multiple frequency and time reference input connectors and a Global Positioning System (GPS) module having an antenna, and an output reference control circuit linked to the PLL and hold-over circuit and multiple frequency and time output connectors. The PLL and hold-over circuit can enable synchronization on either the GPS module or the multiple frequency and time references inputs. The output reference control circuit can generate frequency and timing reference signals for external equipment. The external equipment can include one or more wireless base stations. |
