Small cells have become an integral component in meeting the increased demand for cellular network capacity. Cloud radio access networks (C-RAN) have been proposed as an effective means to harness the capacity benefits of small cells at reduced capital and operational expenses. With the baseband units (BBUs) separated from the radio access units (RAUs) and moved to the cloud for centralized processing,...
500Mb/s Quadrature Phase-Shift Keying (QPSK)-Orthogonal Frequency Division Multiplexing (OFDM) signals on 60-GHz mm-wave are experimentally demonstrated over 100-m graded-index polymer optical fiber with less than 1 dB power penalty at BER = 10-4.
