Hybrid wireless/wired RoF transponder and hybrid RoF communication system using same
First Claim
1. A Radio-over-Fiber (RoF) communication system capable of providing wireless and wired connectivity to at least one client device, comprising:
- a head-end adapted to transmit and receive wired and wireless optical signals over an optical fiber cable; and
at least one transponder optically coupled to the optical fiber cable and configured to convert wired and wireless optical signals to corresponding wired and wireless electrical signals and vice versa, and configured to wirelessly transmit the wireless electrical signals to the at least one client device via an antenna system, whereinthe antenna system and the at least one client device are configured for multiple-input/multiple-output (MIMO) communication within a coverage area formed by the at least one transponder, wherein the at least one transponder comprises;
a converter adapted to convert wireless and wired optical signals from the head-end unit to wired and wireless electrical signals and vice versa; and
a frequency multiplexer/demultiplexer (M/D) electrically connected to the converter and adapted to multiplex and demultiplex the wired and wireless electrical signals.

Abstract
A radio-over-fiber (RoF) hybrid wired/wireless transponder is disclosed that is configured to provide both wireless and wired communication between a hybrid head-end and one or more client devices. The hybrid transponder includes optical-to-electrical (O/E) and electrical-to-optical (E/O) conversion capability and is configured to frequency multiplex/demultiplex electrical “wired” signals and electrical “wireless” signals. The electrical wireless signals are wirelessly communicated to the client device(s) via a multiple-input/multiple-output (MIMO) antenna system within a cellular coverage area. The electrical wired signals are communicated to the client device(s) via a wireline cable that plugs into a wireline cable port on the transponder. The hybrid RoF system includes a hybrid head-end capable of transmitting and receiving wired and wireless optical signals, and an optical fiber cable that is optically coupled to the hybrid head-end and to at least one hybrid transponder. Drop-down transponder configurations that allow for easy wired and wireless connectivity between the client device(s) to the transponder(s) are also disclosed.
