Radio-over-Fibre Transmission of Multiple Wireless Standards for Digital Cities: Exploiting the New Tramway Infrastructure

摘要

The present paper aims at the specific application of Radio-over-Fibre to provide dedicated Wi-Fi access to tramway passengers. The challenge here is to provide wireless services in densely populated city areas based on a real-case scenario targeting public transport. The proposed system targets 2.4 GHz Wi-Fi access at 1 Mbps per user inside a tram, with a wireless bridge at 5 GHz along the track. A chosen design will finally be implemented and evaluated in terms of WiFi coverage, BER and power consumption. Lessons learned will be interpolated for 60 GHz RoF for Wi-Fi access. Replacing the 5-GHz track site solution by a 60 GHz wireless link will bring a significant increase in data throughput (>1 Gbps). We report here performances of running experiments on 2.4 and 5 GHz RoF systems and results on photonic 60 GHz generation for existing fibre backbone between the stations.
