In today’s connected world, many IoT devices operate in remote or hard-to-reach locations. Low-power, long-range, and cost-effective communication technologies like LoRaWAN, Sigfox, and NB‑IoT offer different advantages depending on the use case.
LoRaWAN is an open standard offering long range (urban to rural) and low power consumption. It's ideal for private or closed networks – for example, in industrial or agricultural sensor environments – without ongoing subscription fees.
Sigfox uses ultra-narrowband technology on unlicensed spectrum. It is extremely power-efficient and best suited for simple status messages like fill levels or presence detection, with minimal data payload.
NB‑IoT, a licensed cellular standard (3GPP), delivers strong indoor penetration, reliable performance, and good energy efficiency. It is ideal for smart metering and asset tracking, where coverage and network stability matter most.
Whether you're deploying LoRaWAN gateways, evaluating Sigfox devices, or rolling out a scalable NB‑IoT solution – our team supports you with expert advice, configuration services, and project assistance.

LoRaWAN supports private, long-range networks with flexible deployment. Sigfox is extremely low-power and handles only small data messages. NB‑IoT relies on licensed mobile networks and offers superior indoor coverage and reliability.
Sigfox leads in power efficiency – suitable for rare and short messages. LoRaWAN also allows long battery lifetimes. NB‑IoT consumes more energy but is still efficient for many IoT use cases with moderate message frequency.
Sigfox has the lowest data rate (~100 bit/s), LoRaWAN supports up to 50 kb/s, and NB‑IoT offers up to 250 kb/s. The higher the rate, the better for more complex or frequent data transmission.
Yes. Both Sigfox and NB‑IoT require a service subscription or SIM-based connectivity. LoRaWAN can be operated without recurring costs if you run your own infrastructure.
NB‑IoT performs best indoors and in basements due to its licensed frequency and robust signal penetration. LoRaWAN and Sigfox can also work indoors but require proper gateway coverage nearby.
