The different IoT connectivity technologies

1. Sigfox: An Efficient Solution for IoT

Sigfox is a low-power network technology specifically designed for the Internet of Things (IoT). Thanks to its wide geographical coverage, especially in rural and remote areas, this solution allows devices to be connected over long distances while consuming very little energy. Its main characteristic is the transmission of a small amount of data, around 1.7 KB/day, making it ideal for applications like logistics, traceability, or remote monitoring in the maritime field, agriculture, or infrastructure.

2. LoRa and LoRaWAN: Long-Range, Low-Power Networks

LoRa (Long Range) and LoRaWAN are protocols that allow low-data transmission over long distances. These technologies are perfect for environments where network coverage is weak or expensive to deploy. They offer an effective alternative for smart sensors in agriculture, industry, and smart cities.

3. Bluetooth: Versatile Connectivity for Home Automation

Bluetooth is a widely used technology for home applications such as headsets, connected speakers, or wireless keyboards and mice. This technology is distinguished by:

• Very low energy consumption, ideal for battery-powered devices.
• Medium throughput, allowing the transmission of audio files or commands.
• Short-range, suitable for close-range use.

4. Ultra Wideband (UWB): Precision Geolocation

Ultra Wideband (UWB) is a connectivity technology that allows data transmission over short distances, similar to Zigbee. However, its main advantage is its ability to measure the distance between two communicating objects, making it ideal for indoor geolocation or proximity tracking applications. It is particularly used in security systems, asset tracking in businesses, and advanced home automation devices.

5. NB-IoT and LTE-M: Cellular Connectivity in the Era of 4G LTE

4G LTE and 5G are technologies suited for connected objects that require fast connectivity or very large data volumes, but they remain energy-hungry. NB-IoT (Narrowband IoT) and LTE-M (LTE for Machines) are derivatives of 4G technology optimized for connected objects. They are characterized by low energy consumption and good network coverage.

• NB-IoT is suited for fixed devices such as connected meters.
• LTE-M offers higher throughput and better mobility, ideal for moving objects.

6. Satellite Coverage: A Solution for Remote Areas

When terrestrial network coverage is lacking, satellite coverage takes over. Used for maritime applications, exploration, or critical infrastructures, this solution ensures continuous connectivity in the most hostile environments.

7. Wi-Fi Connection and Network: A Must-Have for Urban Environments

Wi-Fi connections and networks remain widely used solutions for fast and efficient connectivity in buildings, homes, and public spaces. With the evolution of standards such as IEEE 802.11, Wi-Fi now offers enhanced performance for high-speed data transfers.

8. Zigbee: Connectivity for Home Automation and Sensors

Zigbee is a mesh network technology designed for home automation and indoor sensors. It allows stable communication over short distances while consuming little energy. It is a preferred solution for smart homes.
