In this paper, we address the issues of the mobile cell coverage diameter reduction from 400 m/cell to 100 m/cell for the next mobile generation. This feature is most needed in urban areas but not needed on highway roads. To overcome the coverage problem, we propose the idea of the vehicle to vehicle (V2V) communication through both visible light communication (VLC) and low earth orbit (LEO) satellite communication on highway roads. On highways, drivers prefer having continuous coverage to having a high-speed connection if they get covered at portions of the highway. Moreover, modern technology vehicular Manufacturers introduced the drive assist, auto-drive, and hologram aided support features that require a data-hungry high-speed V2V communication. The LEO satellite constellations have global coverage and high-speed connection. However, LEO satellite constellations have limitations in antenna size and motion, transmission power, interference level, and the needed energy, the system memory, and the cost per Mbyte. The VLC benefit from modern advances in vehicular technology to minimize the V2V telecommunication cost and the communication distance can be prolonged by allowing the multi-hop relaying. We build a MATLAB framework for a highway of 20 km two-way straight road with at least four lanes and randomly distributed vehicles moving at variable speeds. Our results show the VLC road gap distance effect on the LEO satellite signal to interference noise ratio (SINR), energy consumption, and data rate. We also study the presence of attenuation and interference conditions effect on the VLC road gap distance.
