Radio Frequency Analysis at Fiber-Based Cell Sites with an OBSAI Interface

Radio equipment at conventional cell sites is located at the base of the tower, transmitting RF signals via coax to antennas at the top of the tower. However, these coax-based feeders produce most problems in cell sites due to their inherent loss and susceptibility to interference. In addition, environmental conditions deteriorate cables and connectors, creating signal reflections and intermodulation.
