High-Speed Wireless Access in Forested Rural Areas Using Analog Radio-over-Fiber Technology

Abstract

A low complexity Ka-band hybrid photonic-wireless link based on a commercial SFP+ module is demonstrated, offering an economical and efficient solution for access provisioning to rural areas. A rain forest environment is emulated and low BER is achieved.

Analog Radio Over Fiber Fronthaul for High Bandwidth 5G Millimeter-Wave Carrier Aggregated OFDM

“…The total power at the output of the SMF is controlled by the second VOA. The RF signal is generated by the heterodyne beating between the OS and CT on a high-speed photodiode (PD) with a bandwidth of 40 GHz [9]. The generated RF wave at a carrier frequency of 28 GHz is amplified by a medium power amplifier (MPA) with 30 dB gain and transmitted over a 2.2 m wireless link using a pair of Ka-band standard gain horn antennas with a gain of 20 dBi each.…”

V-Band Vivaldi Antenna for Beyond-5G Integrated Photonic-Wireless Millimetre Wave Transmitter

“…The beneficial aspect of operating in an unlicensed band resides on the nonexisting channel segmentation allowing carrier aggregation of the whole bandwidth for point-to-point (P2P) links. Thus, broadband signals can be transmitted in outdoor P2P connections bridging buildings, or rural areas with obstacles where fibre deployment is impossible [3], [4]. Moreover, various potential applications in these bands are based on establishing indoor wireless links such as the provision of multi-Gbit/s access in kiosk downloading, rack-to-rack communications in data centres and high-speed WiFi to the home [5].…”
