Evaluation on a Costless 60 GHz OFDM Based Indoor Wireless over Multimode Fiber Green System Employing a Photonic Integrated Smart Antenna

摘要

A 60GHz wireless over fiber indoor system is proposed and evaluated, using a microwave/optical/wireless converged analysis. In order to promote a cost-efficient deployment multimode fiber indoor infrastructure is employed, and a photonic integrated patch antenna combined with a LiNbO_3 modulator scheme for all-optical frequency up-conversion are studied. Using, a 3Gb/s Orthogonal Frequency Division Multiplexing (OFDM) based IEEE 802.15.3c prestandard, and OM-4 graded index multimode fiber (GI-MMF) transmission of 100m, an acceptable performance, in terms of Error Vector Magnitude (EVM) is calculated for a wireless coverage in the order of 10m. A possible system topology is proposed which apart from fulfilling the wired-wireless and low cost requirements, utilizing a FTTB single mode fiber (SMF) feeding and MMF indoor deployment, is appropriate for future green system scenarios through λ-reuse and photonic integrated antenna scheme without post amplification.
