Microcellular radios over optical fibers using subcarrier transmission are described. This paper presents the delivery mechanism with cross-connect switch between base stations and a central station. Theoretical optical link performance are discussed. Carrier-to-noise ratio (CNR) performance is also shown as a function of optical modulation index. Dynamic range improvement is proposed through the use of Frequency modulation (FM) method. Economical diversity by way of base station is also described. This strategy will provide a more cost effectiveness and flexible networks.
