Sensors for a cultivated field must report the results once a day. These sensors are powered by batteries that need to last for years. Which form of connectivity do you use?

1. Bluetooth

2. Wi-Fi

3. LoRaWAN

4. Satellite C-Band

The correct answer is: LoRaWAN

Choosing LoRaWAN as the form of connectivity for the sensors in a cultivated field is the most suitable option due to several key characteristics that align well with the requirements stated in the question. LoRaWAN (Long Range Wide Area Network) is specifically designed for low-power, long-range communication between devices. This protocol excels in scenarios where devices need to transmit small amounts of data infrequently while maintaining energy efficiency. In the case described, the sensors are only required to report results once a day, which fits well with the low data transmission needs of LoRaWAN. Furthermore, LoRaWAN is particularly advantageous for battery-operated devices. The technology allows devices to operate for several years on a single battery due to its low power consumption, which directly addresses the requirement for the sensors to last for years without needing frequent battery replacements. In contrast, other connectivity options would not fulfill the same criteria as effectively. Bluetooth typically operates over shorter distances and may require more frequent connections, which can lead to increased energy consumption. Wi-Fi offers higher data rates suitable for larger data transfers, but it consumes significantly more power than LoRaWAN, making it less desirable for battery-powered devices meant to last years. Satellite C-Band connectivity, while capable of providing extensive coverage, is also
