❓ Frequently Asked Questions
What is IoT connectivity and why is it important?
IoT connectivity enables devices to communicate with each other and with servers, affecting range, power use, data rate, and reliability.
What are the main wireless connectivity options for IoT?
Common options include Wi‑Fi, Bluetooth, Zigbee, Z‑Wave, cellular (NB‑IoT, LTE‑M), LoRaWAN, and satellite, each with different range, power needs, and coverage.
What is LPWAN and when should it be used?
Low-Power Wide-Area Network (LPWAN) provides long-range communication with low power, ideal for sensors that transmit small amounts of data infrequently.
How do NB-IoT and LTE-M differ?
NB‑IoT targets very low data rates and deep indoor coverage; LTE‑M offers higher data rates, lower latency, and better mobility, suitable for more capable devices.
