Frequently Asked Questions

Sigfox USA is deployed in over 24 of the top 25 US metros including, Atlanta, Austin, Boston, Dallas, Chicago, Houston, Las Vegas, Los Angeles, Miami, New York City, Orlando, San Francisco Bay, Seattle, Tampa… to name a few. In 2017, Sigfox USA expanded coverage into 15 new markets, and over 40 of the 50 busiest U.S. airports.

Our network team is working diligently to rapidly deploy the Sigfox IoT network across the United States. For customers who need Sigfox coverage where the public network is not yet available, a self-install connectivity kit, Connectivity as a Service (CaaS) is available. Find out more about CaaS.

We provide the connectivity for IoT devices to communicate, which are designed and built by our robust ecosystem of partners. The one exception is Sens’it Discovery, a device with 5 sensors including temperature, lumens, vibration, open / closed, and magnet detection which is manufactured by Sigfox.

An IoT solution is typically made up of four parts: a chip that determines its functionality which is put into a device built with proper utilization for the use case; connectivity for the device to communicate across; and an IoT cloud platform to receive, analyze, and visualize the data. As IoT network, Sigfox provides the connectivity.

The messages that are sent across our IoT network are 12 bytes or smaller, which keeps the subscription cost low and device battery’s life long. To put that into perspective of what types of messages you can send, GPS coordinates are 6 bytes, temperature is 2 bytes, and speed is 2 bytes.

Depending on the number of messages sent per day, a battery can last ten or more years.

YES! Sigfox technology enables 12 byte uplink messages, and 8 byte downlink message.

Sigfox Build is a one-stop shop that walks you through each step to create your Sigfox enabled IoT solution, from development kit selection to certification. Get started here.

No. In fact, Sigfox connectivity operates in the unlicensed spectrum within the publicly available ISM radio band to transmit messages. It is worth noting unlicensed doesn’t mean unregulated; however, it is free to use, which is a key factor in how we are able to keep connectivity cost significantly lower than traditional IoT connectivity.

Sigfox is ultra-narrow band modulation in which one of the key benefits is highly resilient to interference, as all of the energy is concentrated into a very small bandwidth.

Sigfox has applied security by design in all steps of its protocol and in the development of its infrastructure. Although devices integrating the Sigfox technology are IoT objects, they are not directly connected to the Internet and do not communicate using the Internet protocol. Actually, those devices are not connected to any network or to any base station.

Streaming data is not an option with Sigfox, for a couple of reasons. First, due to FCC regulations only 140 messages can be sent per day per device. Second, this is not what the Sigfox IoT network was designed for; it was designed for the little check-ins — the most valuable data, not all the data.

Technically yes! However, this is under optimal line of sight conditions where there is no obstructions from Mother Nature such as mountains, or humans such as buildings.

Sigfox ensures the messages transmit from the device to our customers’ backend platform. We do not read the data, store the data, analyze it, sell it or anything else, other than pass it from endpoint to your platform.

Yes! Sigfox is complementary to cellular, BLE, and WiFi.
