Introduction to LPWAN IoT networks

The Internet of Things is transforming our connected world. LPWANs (Low Power Wide Area Networks) are essential to this evolution. They offer extended connectivity for devices with reduced energy consumption.

Defining low-speed networks

Low-speed networks, such as LoRaWAN and Sigfox, are designed to transmit limited amounts of data over long distances. They exploit specific frequencies and advanced modulation methods to enhance communication. For example, Sigfox uses Ultra Narrow Band (UNB) technology to increase transmission reliability.

The importance of long-range connectivity

Long-range connectivity is crucial for many IoT applications. It enables coverage of vast areas with little infrastructure. Sigfox can reach 30 to 50 km in rural areas, while LoRaWAN offers 15 km coverage in similar conditions. This capacity is essential for applications such as urban management or connected agriculture.

The challenges of energy consumption

Low energy consumption is a major advantage of low-speed networks. These technologies are designed to run on batteries, offering several years' autonomy. LoRaWAN and Sigfox minimize transmissions, which is crucial for large-scale deployment of the Internet of Things. This reduces maintenance costs and environmental impact.

LoRaWAN technology overview

LoRaWAN, an innovative communications protocol, is based on LoRa technology. LoRa was launched in Grenoble in 2009. Semtech acquired it in 2012. The LoRa Alliance, with over 500 members, has propelled LoRaWAN internationally.

By 2020, LoRaWAN was present in 162 countries, with 148 network operators. This expansion illustrates the reliability of m2m communication. LoRa modulation, based on the Chirp Spread Spectrum, enhances resistance to interference.

LoRaWAN stands out for its remarkable range, reaching 15 km in rural areas. Its maximum data rate of 22 kbps is suitable for a wide range of IoT applications. Adaptive Data Rate optimizes energy efficiency and data rates, enhancing network performance.

Unlike Sigfox, LoRaWAN is an open protocol. It enables bidirectional communication and offers advanced functionalities such as geolocation. LoRaWAN devices run on battery power for years, making them ideal for long-term deployments.

In the lorawan vs sigfox debate, LoRaWAN stands out for its flexibility. It allows network parameters such as frequency and data rate to be adjusted, offering superior adaptability for a variety of m2m communication scenarios.

Sigfox architecture and operation

Sigfox, a French company founded in Toulouse in 2009, has designed an innovative architecture for the Internet of Things. Its proprietary network represents a revolutionary solution for fleet management and the development of smart cities.

The Sigfox proprietary network

Sigfox has complete control over its network, guaranteeing extensive coverage and efficient management. Devices transmit directly to Sigfox base stations, avoiding intermediate gateways. This star-shaped structure facilitates deployment in both urban and rural areas.

UNB communication protocol

Sigfox's Ultra Narrow Band (UNB) protocol uses frequencies specifically designed for the IoT. Communication is mainly unidirectional, from devices to the cloud. Transmission speeds are low, 100 bps in Europe and 600 bps in the U.S., optimized for low energy consumption.

Infrastructure and deployment

The Sigfox network offers impressive coverage: 3 to 10 km in urban areas and up to 50 km in rural areas. It covers 98% of the French population and operates in 82 countries. Each sensor requires an operator subscription to communicate with the Sigfox cloud. This centralized approach facilitates the deployment of large-scale IoT solutions for fleet management and smart city projects.

lorawan vs sigfox: Comparative technical analysis

The technical comparison between LoRaWAN and Sigfox highlights crucial differences for connected objects. Both LPWAN technologies use the ISM 868 MHz bands in Europe, but they adopt distinct strategies.

LoRaWAN stands out for its flexibility, offering adjustable data rates from 0.3 to 50 kbps. It can transmit messages of up to 243 bytes, making it ideal for large volumes of data. Its star topology, with gateways, adapts to both public and private deployments.

Sigfox, on the other hand, takes a minimalist approach. It offers a fixed data rate of 100 bps and messages limited to 12 bytes, suitable for light transmissions. Its star network communicates directly with Sigfox base stations, simplifying the infrastructure.

In terms of security, LoRaWAN uses AES-128 encryption with separate network and application keys. Sigfox, on the other hand, uses a proprietary mechanism that is potentially less robust due to the shorter message length.

LoRaWAN stands out for its scalability, thanks to its multiple channels and spreading factors. Sigfox, with its ultra-narrow bandwidth, offers good resistance to interference, but can be challenging in dense environments.

The choice between lorawan and sigfox depends on the specific needs of connected objects in terms of data volume, transmission frequency and deployment environment.
