A wireless communication protocol LoRaWAN also referred to as long-range wide-area network, was developed for communicating over long distances between low-power devices.

Here is an overview of its primary components, along with its functioning:

  1. LoRa: LoRa stands for Long Range. It has been rendered feasible by physical layer technology. It provides long-range communication at relatively low power consumption through the utilization of spread spectrum modulation techniques. LoRa devices can connect over long distances up to several kilometres even in densely populated cities with structures like skyscrapers.
  2. Key Components:  The key components of a LoRaWAN network include network servers, gateways (that serve as middlemen between end devices and the network server), application servers (that process data for specific applications or services), and end devices (that include sensors and other data gathering devices).
  3. Low Power: Low power consumption is one of the key advantages of LoRaWAN technology. Nodes also referred to as devices, are typically powered by batteries that last for years without needing frequent replacement. Due to this, it is ideal for applications with limited power supply or accessibility.
  4. Topology: In general, LoRaWAN utilizes a star-of-stars network topology. In this arrangement, one or more intermediary devices known as gateways, enable end devices like sensors, actuators, etc. to connect with a centralized network server. Upon receiving the messages from endpoints within their coverage area, gateways forward them over a backhaul connection, typically the internet to the network server.
  5. Device Classes: In order to satisfy the requirements of diverse application scenarios, LoRaWAN supports multiple device classes. Class A, Class B and Class C devices belong to these classes. Class A devices consume the least amount of electricity but offer little flexibility in communication, Class B devices in LoRaWAN offer scheduled receive windows, balancing low power consumption with increased communication flexibility. On the other hand, Class C devices consume more power but provide continuous connectivity.
  6. Security: One essential component of LoRaWAN is security. The data sent between devices and the network server is ensured to be authentic, private, and intact through the use of encryption and authentication methods. Secure communication additionally includes the implementation of key management and secure key exchange protocols.
  7. Scalability: LoRaWAN networks are capable of seamlessly expanding from a few devices to thousands or even millions of devices. LoRaWAN is suitable for extensive IoT deployments due to its scalability, long-range, and low-power features.
  8. Cost Effective: When considering alternative communication technologies such as Wi-Fi or cellular, the infrastructure needed to establish LoRaWAN networks is comparatively less expensive. Due to this, LoRaWAN is an affordable option for extensive IoT deployments. Furthermore, because LoRaWAN devices require fewer external power sources or frequent battery replacements, their low power consumption lowers total costs.
  9. Compatibility: LoRaWAN is a universal standard that facilitates smooth communication between devices developed by various manufacturers within the same network. Developers can select from a range of LoRaWAN compatible devices and solutions due to its interoperability, which encourages creativity and competitiveness in the IoT market.
