LPWA LPWAN Technologies Explained: What Are Low-Power Wide-Area Networks?

How LPWA LPWAN Technologies Work

These network technologies focus on using specific radio frequencies and modulation types optimized for:

• Range over speed: Sacrifice high data rates to achieve long range

• Ultra-low power consumption: Optimized to last for years on a single battery

• Deep penetration: Signals reach indoor and underground locations

• Low-cost: Cheaper infrastructure than traditional cellular technologies

This makes them the perfect fit for IoT solutions and use cases where connected devices have to transmit small amounts of data occasionally with low latency requirements, e.g. smart meters, sensor values, device status, or asset tracking information.

Multiple cellular LPWA and wireless communication technologies fall under the LPWA LPWAN umbrella, all designed for low power consumption while providing wide area networks that cover distances of many kilometers through base stations and gateways. They allow IoT devices and modules to send small bits of data through low-bandwidth data transfer, such as sensor readings, status updates, or location information, over long distances while still providing years of battery life. This scalability makes them useful for real-time monitoring in IoT applications such as smart agriculture, smart cities, industrial IoT, healthcare, and automation.

LPWA LPWAN Technologies: Sigfox, LoRa, and NB-IoT

Sigfox Explained: Global LPWA Network Technology

Sigfox pioneered commercial LPWA markets with ultra-narrow band (UNB) technology. Founded in 2009, the French company provides global IoT networks coverage across 45+ countries through local operator partnerships and endpoint connectivity.

Sigfox features:

• Ultra-narrow band radio for maximum range (up to 40km rural)

• Extremely low power consumption (10+ year battery life)

• Simple device integration with minimal hardware

• Global coverage through operator networks

LoRa/LoRaWAN Technology

LoRa (supported by the LoRa Alliance) offers private wireless network deployment capabilities using chirp spread spectrum modulation. This technology provides greater data rates flexibility and throughput than Sigfox while maintaining excellent power efficiency.

LoRa advantages:

• Private network control

• Moderate data rates (300 bps - 50 kbps)

• Enterprise-friendly deployment

• Range up to 15km rural, 5km urban areas

NB-IoT (Narrowband IoT)

Narrowband IoT (NB-IoT) operates on licensed cellular spectrum through LTE networks, providing carrier-grade reliability and security. This cellular IoT and cellular LPWA solution integrates with existing LTE Cat infrastructure and 3GPP standards.

NB-IoT benefits:

• Cellular networks reliability

• Higher data rates (20-250 kbps)

• Licensed spectrum operation

• Urban areas coverage optimization

LPWA Use Cases: Where Low-Power Networks Excel

Smart Cities:

• Street lighting management and environmental monitoring

• Waste management optimization and parking solutions

• Smart home integration and urban areas connectivity

Agriculture:

• Soil moisture monitoring and livestock asset tracking

• Weather stations and crop condition analysis through large-scale deployments

Industrial Applications:

• Asset tracking and equipment monitoring modules

• Supply chain visibility and remote surveillance with LTE-M integration

LPWA LPWAN Network History: Older Than You Think

The origins of LPWA LPWAN technology trace back to radio communications developed during World War I. Armies implemented low-power, long-range radio to enable reliable communication across battlefields. The WWI Narrow Band Evaluation showed that even with less data speed, longer range and power savings can address communications problems - a principle that is at the core of today's LPWA.
