LoRa (Long Range) is a wireless communication protocol designed for long-range and low-power IoT applications. It operates in the sub-GHz frequency bands, enabling devices to transmit data over vast distances while consuming minimal energy.
Key Features of LoRa
- 🌍 Long Range: Reach up to 15 km in urban areas and 50 km in rural environments (depending on the frequency and obstacles).
- ⚡ Low Power: Battery life can extend for years in many devices, ideal for remote sensing.
- 📡 Low Cost: Simple hardware and open standards reduce deployment expenses.
- 🔐 Secure: End-to-end encryption ensures data privacy.
Common Use Cases
- 🏗️ Smart Cities: Monitoring environmental sensors, streetlights, and parking systems.
- 🧬 Agriculture: Soil moisture tracking and livestock monitoring.
- 📺 Consumer Electronics: Asset tracking and home automation.
Technical Highlights
- Frequency Bands: 868 MHz (EU), 902–928 MHz (US), 940 MHz (Asia).
- Modulation: Chirp Spread Spectrum (CSS) for robust signal quality.
- Network Types: LoRaWAN (for mesh networks) and LoRa (for star networks).
- Data Rate: Varies from 0.3 kbps to 50 kbps, depending on distance and bandwidth.
