Connecting the unreachable - with minimal power.

Long-range communication refers to the wireless transmission of data over kilometers of distance — often 1 km to over 15 km — between two devices, usually with low power and low data rates. It’s how IoT devices like remote sensors or trackers send information even when they’re far from Wi-Fi or cellular networks.

Technologies That Enable Long-Range Communication:

• LoRa / LoRaWAN – Low-power, long-distance (2–15+ km), perfect for sensors.

• Sigfox – Ultra-narrowband, similar to LoRa, but proprietary.

• NB-IoT – Cellular-based, lower power than 4G, good for cities.

• Sub-GHz RF (433/868/915 MHz) – Raw radio, often used in custom protocols.

• Satellite IoT – When there's no ground signal at all (e.g. in the Arctic or open sea).

• Cellular networks (4G, 5G) can reach 10-50 kilometers from cell towers and offer high data rates, but consume significant power and require expensive data plans.

• Radio frequencies like ham radio can reach hundreds or thousands of kilometers under the right atmospheric conditions.

Real-World Analogy:

Think of it like a whisper that can be heard across a football field — not loud, not fast, but it reaches far and uses almost no energy.

Why long range matters for IoT:

Many IoT applications need to work in remote locations - like monitoring oil pipelines in deserts, tracking wildlife in forests, or sensors on farms far from cities. These devices often need to run on batteries for years while still being able to send their data back to central systems. Long range, low-power technologies make this possible without requiring expensive infrastructure in every remote location.
