LoRa Iot or LoRaWan IoT represents the future for smart buildings. Until recently, the Building IoT Market has been dominated by wired sensors using Modbus and BACnet protocols. In recent years, different wireless communication technologies such as Zigbee, EnWave, Bluetooth have entered the market. Despite the hype behind them, their short-range, security risks, and hard-to-configurable network architecture make them disadvantageous due to the complex nature of commercial buildings. Sensgreen fostered the recently emerged wireless communication protocol “LoRaWAN” for ease of installation and scalability.

LoRaWAN is a non-cellular wireless communication protocol. LoRaWAN enables long-range communication. LoRaWAN is both the communication protocol and system architecture for LoRa IoT networks. The LoRaWAN technology stack is the best choice for connected cities because of its long signal range and minimal power requirements.

LoRaWAN brings different advantages to the market: 

Ultra-low energy consumption: Compared to other data transmission protocols, LoRaWAN smart city requires little power, preserving the battery life of devices.

Range: The wider the coverage, the better and cheaper the IoT infrastructure. With LoRaWAN, depending on conditions, signals can reach 10 to 15 kilometers in urban areas, and 1 km in buildings. 

Cost efficiency: LoRaWAN smart building architecture is comparatively easy to deploy within IoT infrastructure. Deployment on frequencies that don’t require licensing and low-cost base stations make LoRaWAN applications economically viable. Add to this the low cost of LoRaWAN IoT devices that can run for years on the same battery and reduced site visit costs for device maintenance.

Open-source. Being an open-source protocol, LoRaWAN covers all the community best practices. LoRa Alliance members do their part to propel LoRaWAN-powered IoT initiatives.

Bi-directional communication: LoRaWAN-enabled IoT network units (sensors, for instance) can both transmit and receive data. Sending data to networks and receiving information in return, LoRaWAN equipment can deliver status messages even to remote locations.

Good building penetration and low path loss: LoRaWAN radio waves can pass through obstacles and reach sensors indoors, such as those placed in elevators, basements, or underground parking garages.
