Study Notes
Low Power Wide Area Network (LPWAN)
- LPWAN is a wireless telecommunication network designed for long-range communication at a low bit rate.
- These networks are suitable for connecting battery-operated sensors and other "things" (connected objects).
- Legacy non-cellular wireless technologies are not ideal for connecting low-power devices over large geographical areas, often limited to hundreds of meters.
- Cellular networks provide wide area coverage but do not offer sufficient battery life for some applications.
- LPWAN achieves long range and low power operation, but at the cost of a low data rate and higher latency.
- This technology is not suitable for industrial IoT, vehicle-to-vehicle, and vehicle-to-infrastructure applications that require high data rates and quick response times.
- However, they meet the needs of applications in smart cities, smart metering, and home automation that require low data transmission and infrequent data exchange.
Applications of LPWAN
- Smart City Applications
- Personal IoT Applications
- Smart Grid & Smart Metering
- Industrial Assets Monitoring
- Critical Infrastructure Monitoring
- Agriculture
- Home Automation & Safety
- Logistics
- Wildlife Monitoring & Tracking
5G Network Architecture
- 5G networks can provide speedy cellular data throughput with very low latency and support for ultra-dense network connections.
- 5G networks are capable of speeds up to 10 Gbps while maintaining reliable connections for thousands of devices simultaneously.
LPWAN Architecture
- LPWAN is designed for long-range communication with low energy consumption.
- LPWAN devices are characterized by low complexity and long range.
- LPWAN operates in license-free frequency bands and some licensed frequency bands, including cellular bands.
Technologies Concepts for LPWAN Market Players
- LoRaWAN: A low-power wide area network utilizing LoRa technology.
- Sigfox: A global network operator utilizing a proprietary PHY layer protocol covering sub-1GHz radio frequencies.
LPWAN Design Goals and Techniques
- Long Range: Designed for wide area coverage. Extends signal across long distances (kilometers).
- Ultra-Low Power Consumption: Designed for operation using minimal power consumption over time. Uses mechanisms like duty cycling, enabling devices to turn off when not needed.
- Low Cost: Facilitates reduced hardware complexity and need for minimal infrastructure, like a single base station connecting tens of thousands of devices. Uses available un-licensed bands.
- Scalability: This is achieved through diversity techniques, leveraging cooperation, and multi-channel communication.
- Quality of Service: Aims to accommodate varying requirements for application needs in terms of delay tolerance for applications like smart metering versus the speed needed for security applications.
Broadband vs Narrowband
- Broadband is suitable for high data rate applications but requires higher power and significant bandwidth.
- Narrowband communications are suitable for long-range, low-power applications but transmit lower data rates.
- Narrowband technologies are preferred for IoT applications.
