Solar Smart Lighting

  • Solar Smart Lighting

  • Solar Smart Street Light IoT Communication Solutions

  • Solar smart street lights combine renewable energy with intelligent communication to deliver efficient, grid-independent lighting. Two widely used communication options are:
  • LoRa-MESH: A low-power, long-range wireless mesh network.
  • 4G/LTE: A high-speed, cellular-based point-to-cloud communication.

  • Key Differences Between Solar LoRa-MESH and Solar 4G/LTE Solutions

  • Feature Solar LoRa-MESH Solution Solar 4G/LTE Solution
    Communication Type Wireless MESH (node-to-node + gateway) Cellular (each node connects directly to the cloud)
    Topology Mesh topology (with relay routing) Star topology (direct-to-cloud)
    Internet Connection Via Gateway (shared among nodes) Via SIM card (per light or per group)
    Coverage Range 1–5 km with relays Nationwide, depends on telecom signal
    SIM Card Required No Yes
    Cost (Per Node) Lower (shared gateway, no SIM/data fees) Higher (SIM + data fees per unit or group)
    Installation Complexity Medium (gateway setup, MESH configuration) Simple (plug-and-play with good signal)
    Reliability High (self-healing, peer relaying) High (if signal is stable)
    Scalability Excellent for large-scale deployments Good for small/medium sites or remote areas
    Data Transmission Speed Moderate (enough for lighting control) High (supports video/sensor-heavy applications)

  • Advantages of LoRa-MESH & 4G/LTE Solution

  • Solar LoRa-MESH Solution – Advantages
  • No SIM or cellular data cost 
  • Self-healing network ensures coverage even in signal-blocked areas 
  • Ideal for large urban/rural networks with dense or scattered lights 
  • Flexible gateway placement reduces infrastructure dependency 
  • Lower total cost of ownership (TCO)
 
  • Solar 4G/LTE Solution – Advantages
  • Direct, cloud-to-node communication without the need for gateways 
  • Faster data transmission – supports cameras, environment sensors, etc. 
  • Easier to deploy in remote locations with cellular coverage 
  • Simplified network management — no need for MESH setup or maintenance 
  • Ideal for high-value standalone lights or small clusters
