What is LoRaWAN?

LoRaWAN stands for Long Range Wide Area Network. It is a wireless communication protocol designed for long-range communication between low-power devices, typically used in the context of the Internet of Things (IoT). Here’s a breakdown of the key components and how LoRaWAN works:

LoRa (Long Range): LoRa is a modulation technique that allows for long-range communication between devices while consuming minimal power. LoRa operates in the sub-GHz frequency bands (usually around 868 MHz in Europe and 915 MHz in the US) which enables it to penetrate obstacles and cover long distances, making it suitable for outdoor deployments.

Wide Area Network (WAN): LoRaWAN is a wide-area network protocol built on top of LoRa technology. It enables communication between end-devices (sensors, actuators, etc.) and the network infrastructure over long distances. LoRaWAN networks are typically deployed by telecom operators, businesses, or communities to provide connectivity for various IoT applications.

Network architecture

  • End Devices: These are the IoT devices equipped with LoRa transceivers. They collect data from sensors or send commands to actuators.
  • Gateways: Gateways act as the intermediary between end devices and the network server. They receive LoRa transmissions from nearby devices and forward them to the network server through an IP connection (via Cellular, Wi-Fi, Ethernet or Satellite Communications).
  • Network Server: The network server manages the communication between gateways and end devices. It handles tasks like authentication, encryption, and routing of messages.
  • Application Server: The application server processes the data received from end devices and performs any necessary analysis or actions. It’s the interface between the LoRaWAN network and the end-user applications.

Key features of LoRaWAN with SenArch

  • Solar and off-grid connectivity:
    LoRaWAN gateway deployment with less complexity and lower costs from not having to pull power and data cables. It has never been easier to install gateways on the roofs of buildings, enabling off-grid and carbon neutral network infrastructure for seamless wireless connectivity with IoT devices, both indoors and outdoors.
  • Cost-effectiveness:
    LoRaWAN operates on unlicensed frequencies, which makes it a cost-effective solution for IoT applications that require wide area coverage. This reduces infrastructure costs and enables cities to deploy a large number of IoT devices without incurring significant expenses.
  • Long-range coverage:
    LoRaWAN’s long-range connectivity allows IoT devices to be deployed over large areas, providing comprehensive coverage of the city. This makes it possible to monitor and control various aspects of the city’s infrastructure and services, including street lights, traffic, air quality, waste management, and more.


  • Scalability:
    LoRaWAN’s star-of-stars network topology enables it to support large-scale networks with millions of devices. This makes it possible to connect a wide range of IoT devices throughout the city, enabling real-time monitoring and control of city infrastructure and services.


  • Low-power consumption:
    LoRaWAN’s low-power consumption enables IoT devices to operate for long periods on a single battery charge. This reduces maintenance costs and makes it easier to deploy and manage large numbers of IoT devices throughout the city.


    • Security:
      LoRaWAN includes advanced security features, including end-to-end encryption, to ensure the privacy and security of data transmitted over the network. This protects the city’s infrastructure and services from cyber-attacks and other security threats.

    Applications of LoRaWAN
