From the following, which technology is commonly used for long-range IoT communications?

Long-range IoT needs a technology that works over wide areas while sipping power from small batteries. LoRa fits that need because it uses a low-bandwidth, spread-spectrum method in sub-GHz frequencies and builds a strong link budget. That combination lets devices send small amounts of data over kilometers, often for years on a single battery, which is ideal for sensors spread across a city or countryside. This is why LoRa is commonly chosen for wide-area sensor networks, remote monitoring, and similar applications. Zigbee is designed for short-range, indoor or campus-scale networks and relies on mesh to extend reach, but it doesn’t scale well to kilometers. NFC is intended for very near-field communication, just inches away. Wi‑Fi delivers higher data rates but uses more power and has much shorter range, making it unsuitable for long-range, low-power IoT deployments.
