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.
