Network infrastructure and switching through streetlights

By | September 27, 2018

A plurality lampposts or streetlights comprising Wireless data communication modules in a lighting enclosure, providing a 5th Generation (5G) base station cell, high speed radio frequency (RF) or high speed Visible Light Communication (VLC) with wired backhaul, possibly fibre optic. The cell has range covering a section of nearby road, which may achieve rates up to 5Gbps. The vehicles information (speed, direction and data requirements over a period of time) are determined. The nearest communications module negotiates with devices in the vehicle. A staggered relay buffer is calculated for queuing data at a series of neighbouring lampposts for uninterrupted transmission during computed time intervals as the vehicle is moving past each lamppost. The relay buffer may be calculated by a router or caching service. The wireless data communication may support a WLAN (Wi-Fi (RTM) or Bluetooth (RTM)) within the vehicle, which transmits vehicle information. Some cells may be microcells or femtocell or mounted on generic cell tower masts. Mains power or power over Ethernet (POE) may be used in the lamppost, which may comprise an environmental sensor. The vehicle may be autonomous. Some steps may be repeated at fixed intervals, after passing each streetlight or at unexpected stops.
