How do the devices installed in the field send the data they read?
In the constantly evolving technology landscape, connectivity has become essential among solutions, with special emphasis on the Internet of Things (IoT). In this context, two technologies have stood out: LoRa (Long Range) and NB-IoT (Narrowband). Both offer efficient ways to connect devices to the network.
Connectivity: LoRa and NB-IoT
Devices can be compared to "mini cell phones": they exchange information with nearby antennas, and open a communication channel to send data.
Through spread spectrum modulation, the LoRa signal can travel significant distances, overcoming obstacles and penetrating dense urban areas. Therefore, the LoRa standard is widely used and requires its own antennas.
If there are no antennas in a city, a query is made to the connectivity company to verify interest in installing them. The data transmission time is very short; it is a way to save the device's battery, which should function for 10 years without replacing the battery.
The newer NB-IoT standard uses the common cell phone antennas in the 5G standard. So it already has many antennas already installed and coverage practically throughout the country. With this technology, it is possible to remotely update the device's control program. Like LoRa, it makes short communications and works for 10 years without replacing the battery.
Stattus4 already works with both standards, currently with NB-IoT for pressure devices and LoRa for the rest.
These technologies allow sensors installed throughout the distribution network to communicate precise data in real-time, providing valuable insights for the loss management team.
