Robust Cellular connectivity-Based Smart LED Street Lighting System: A Platform For Innovative Mission Critical Smart City IoT Applications

Smart connected LED streetlights are emerging as an important infrastructure that can support basic lighting control services as well as a wide range of current and future smart city applications and services. Each smart streetlight is turned into multi-sensor-equipped smart node, a sensor `hub' node, capable of capturing and transmitting/receiving real-time data (digitally controllable nodes). A smart LED has sensors embedded into and connectivity to the cloud. This paper assesses the feasibility and quantifies the performance of commercial point-to point (P2P) 4G LTE cellular networks when used to provide robust connectivity between a massive number of smart streetlight hub nodes and the cloud. Each smart streetlight hub node is assumed to be running simultaneously few basic lighting control services as well as smart city services and applications, including mission-critical with strict latency and reliability requirements, with particular emphasis on HD IP video surveillance cameras.
