What technology is characterized by long-range, power-saving features for wireless communication with IoT devices?

1. Wi-Fi

2. LPWA

3. Bluetooth

4. NFC

The correct answer is: LPWA

The technology characterized by long-range, power-saving features for wireless communication with IoT devices is indeed Low Power Wide Area (LPWA) technology. This type of communication is specifically designed to connect a large number of sensors and devices over broad areas while consuming minimal power. LPWA networks support devices that require long battery life, often lasting years while transmitting small amounts of data intermittently. This makes them ideal for IoT applications such as smart meters, environmental monitoring, and agricultural sensors, where devices need to be deployed in remote locations and cannot easily be recharged or replaced. Unlike other options, which serve different purposes or have limitations regarding range and power consumption, LPWA is specifically built to address the needs of IoT devices in terms of both distance and energy efficiency. Wi-Fi, while faster and suitable for higher data throughput, typically consumes more power and has a shorter range. Bluetooth focuses on short-range communication and also tends to consume more power than LPWA. NFC is designed for very short-range communication, making it unsuitable for the long-distance requirements typical of IoT applications.
