LoRa vs. Sigfox: What are the Difference?

Wireless communication technologies have revolutionized the way we communicate and interact with our surroundings. They have enabled the growth of the Internet of Things (IoT) and have allowed for seamless communication between devices, sensors, and the cloud. Wireless communication technologies come in different forms, each optimized for specific use cases and applications. These technologies include cellular networks, Wi-Fi, Bluetooth, Zigbee, LoRa, LoRaWAN, and Sigfox, among others.

What is LoRa and LoRaWAN?

The LoRa (short for Long Range) wireless communication technology, which employs chirp spread spectrum modulation and operates in the sub-gigahertz frequency regions, enables long-range communication between low-power devices. Chirp spread spectrum modulation disperses the signal over a broad frequency band to extend the signal’s range and minimize interference.

When devices need to transfer little amounts of data over long distances, such as in smart cities, smart agriculture, and industrial automation, LoRa is the best option. LoRa is designed to provide low-power, long-range connections for Internet of Things (IoT) devices. Anyone can use LoRa since it is made to function in unlicensed frequency bands and does not require a license.

The LoRaWAN protocol provides a standardized method for Internet of Things (IoT) communication by running on top of the LoRa physical layer. Together with the system architecture and communication protocol of the network, it describes the topology, device activation, security, and data rates of the network. A range of applications can be supported by LoRaWAN, a low-power, low-cost, and scalable IoT connection solution.

End devices, gateways, and a network server are the fundamental building blocks of LoRaWAN networks. End devices are low-power IoT gadgets that use LoRa technology to send data to gateways. Data is collected from endpoints by gateways and sent to the network server. The network server is in charge of administering the network, which includes data routing to the proper application server, device activation, security, and network management.

In a LoRaWAN network, end devices and gateways connect with one another directly and with the network server via a star topology. End devices are frequently battery-operated and made to use less power by sending data only when it is required. Secure communication and over-the-air upgrades for end devices are also supported by LoRaWAN.

What is Sigfox?

A wireless communication system created exclusively for the Internet of Things is called Sigfox (IoT). Little amounts of data are transmitted across vast distances utilizing unlicensed radio frequency bands using an ultra-narrowband modulation technique. Sigfox is meant to support IoT applications that need long-range communication and low power consumption and is tuned for low-power, low-cost hardware.

End devices, base stations, and a cloud-based backend are the three primary parts of Sigfox networks. Low-power Internet of Things (IoT) endpoints uses Sigfox to send data to base stations. End-device data is received by base stations, which then transmit it to a cloud-based backend. Data routing to the proper application server, device registration, security, and network management are all handled by the backend.

The long-range capacity of Sigfox is one of its primary characteristics. Depending on the location and the particular installation, Sigfox can carry data over distances of up to several hundred meters in urban areas and several kilometers in rural areas. As a result, Sigfox is appropriate for use in applications like asset tracking, smart cities, and industrial automation where devices may be spread out and require long-distance communication.

Secure communication and over-the-air upgrades for end devices are also supported by Sigfox. Devices employ a specific identification to authenticate and encrypt data transfer after registering with the Sigfox backend. This aids in protecting the confidentiality and integrity of data sent across a network.

The difference between Sigfox and LoRa

Two wireless communication systems created for the Internet of Things are Sigfox and LoRa (IoT). Although they are both designed for low-power, long-distance communication, there are several significant distinctions between the two technologies.

The modulation method used to transmit data is the primary distinction between Sigfox and LoRa. Using its ultra-narrowband modulation technique, Sigfox enables extremely long-distance communication with little battery usage. In contrast, LoRa employs a chirp spread spectrum modulation technique that, while not as fast as Sigfox, nevertheless enables long-range communication.

The network architecture of Sigfox and LoRa also differs. Its own management oversees the Sigfox network, which is a private network. LoRa, on the other hand, is an open standard that anyone can use to create their own network. This means that Sigfox networks are standardized and centrally maintained, but LoRa networks can be modified and fitted to particular use cases.

Sigfox networks also have some limitations in terms of data rate and payload size. Sigfox can transmit up to 12 bytes of data per message and up to 140 messages per day, while LoRa can transmit up to 243 bytes of data per message and at a higher data rate than Sigfox. This makes LoRa better suited for applications that require higher data rates and larger payloads.

In terms of availability, Sigfox has a global network that covers many countries, while LoRa networks are more localized and may require building or joining a specific network for a given location.

Use cases for Sigfox and LoRa

Sigfox and LoRa have the following applications:

Sigfox use cases include:

Asset tracking: Across vast distances, Sigfox can be used to track things including cars, containers, and machinery.

Smart cities: Sigfox can be used to keep an eye on and manage city facilities including lighting, traffic lights, and parking meters.

Agriculture: Sigfox technology can be used to track soil moisture, temperature, and other environmental elements.

Automation in the industrial sector: Sigfox can be used to track and manage machinery and operations.

Smart home: Devices like sensors, thermostats, and security systems can be connected to and managed by Sigfox.

LoRa use cases include:

Smart meters: LoRa can be used to monitor and manage utility meters like those for electricity, gas, and water.

Asset tracking: Across long distances, LoRa can be used to track things like cars, containers, and machinery.

Smart agriculture: LoRa can be used to monitor and manage irrigation systems, soil moisture, and other environmental aspects in agriculture.

Smart cities: LoRa can be used to monitor and manage city infrastructure, including traffic lights, parking meters, and streetlights.

Industrial automation: LoRa can be used to monitor and manage machinery and procedures in the industry.


Wireless communication technologies like Sigfox, LoRa, and LoRaWAN enable connectivity between IoT devices over great distances and with little power usage. The growth of the Internet of Things has been hastened by the development of LoRa, LoRaWAN, and Sigfox, three key wireless communication technologies that also enable a wide range of smart applications in various industries (IoT).
