Correct option is D
LoRaWAN (Long Range Wide Area Network) is a communication technology designed for long-range, low power consumption applications. It is widely used in IoT (Internet of Things) applications due to its ability to connect devices over large distances with minimal energy usage, making it ideal for smart cities, agriculture, and other IoT solutions.
Important Key Points:
1. LoRaWAN: LoRaWAN is optimized for low power consumption, allowing devices to operate for years on a small battery, making it ideal for IoT applications that require long-range communication with minimal power usage.
2. Long-Range Connectivity: LoRaWAN provides long-range connectivity, allowing IoT devices to communicate over several kilometers in rural and urban areas, which is essential for various applications such as monitoring and remote sensing.
3. IoT Popularity: LoRaWAN’s combination of long-range, low power, and scalability makes it highly popular in IoT applications, where devices often need to communicate over vast areas with minimal energy consumption.
Knowledge Booster:
· Bluetooth: Bluetooth is commonly used for short-range communication, typically within a few meters. It does not provide the long-range connectivity required for many IoT applications.
· NFC: NFC (Near Field Communication) is used for very short-range communication, typically within a few centimeters, and is not suitable for long-range IoT applications.
· Wi-Fi: While Wi-Fi offers good speed and bandwidth for short-range communications, it consumes more power and does not provide the long-range connectivity that LoRaWAN offers.
