SigFox plans Silicon Valley IoT cellular network

Writing for MIT’s Technology Review, Tom Simonite confirms that SigFox plans on building a cellular network for the rapidly growing Internet of Things (IoT) in San Francisco later this year. 

According to SigFox, the wireless network is intended to make it cheap and practical to link anything to the Internet, including smoke detectors, dog collars, bicycle locks and water pipes.

“If you want to get to billions of connections like that, you require a completely new type of network,” Luke D’Arcy, director of SigFox’s operations in the US, told the publication.

As Simonite notes, the Silicon Valley network is slated to leverage the unlicensed 915-megahertz spectrum band typical used by cordless phones.

“Objects connected to SigFox’s network can operate at very low power but will be able to transmit at only 100 bits per second—slower by a factor of 1,000 than the networks that serve smartphones. But that could be enough for many applications,” he explains. 

”A SigFox base station can serve a radius of tens of kilometers in the countryside and five kilometers in urban areas. To connect to the network, a device will need a $1 or $2 wireless chip that’s compatible, and customers will pay about $1 in service charges per year per device.”

It should be noted that French startup SigFox recently showcased its Atmel-powered global cellular connectivity solution for the IoT at the Atmel booth during Embedded World 2014 in Nuremberg, Germany.

According to company rep Jacques Husser, SigFox-ready devices connect to the Internet without any geographically dependent connectivity costs or location-specific network configuration. The worldwide connectivity solution is managed through the Sigfox Network Operator partnership program, effectively linking local ecosystems to the global network.

That is why, says Husser, the phrase “one network, a billion dreams” has become the company’s slogan. 

Indeed, SigFox utilizes UNB (Ultra Narrow Band) radio technology to connect devices to its global network. The use of UNB is key to providing a scalable, high-capacity network, with very low energy consumption, while maintaining a simple and easy to rollout star-based cell infrastructure.

 The network operates in the globally available ISM bands (license-free frequency bands) and co-exists in these frequencies with other radio technologies – without any risk of collisions or capacity problems.

SigFox currently uses the most popular European ISM band on 868MHz (as defined by ETSI and CEPT), along with 902MHz in the USA (as defined by the FCC), depending on specific regional regulations.

SigFox secures communications in a number of ways, including anti-replay, message scrambling and sequencing. Perhaps most importantly, only the device vendors understand the actual data exchanged between the device and the IT systems. Simply put, Sigfox acts as a transport channel, pushing the data towards the customer’s IT system.

Video: Atmel @ Embedded World (Day 0)



Atmel is at Embedded World 2014 in Nuremberg Germany, where the company has launched a number of new products to drive smart, connected devices in the era of the Internet of Things (IoT).

Some of the new products, along with interactive demos, will be showcased on Days 1-3 of the show at the official Atmel booth located in Hall 4A / #4A-220. Exhibits and demos include:

  • Capacitive touch capability with Atmel’s QTouch technologies – Highlights various home appliances to demonstrate conductive immunity and moisture tolerance, along with an Xplained Pro board and capacitive touch extension board.
  • New ARM MCU solutions – A SAM4E data logger with signal processing based on Atmel’s ARM Cortex-M4 MCUs and a SAM D20 global positioning system tracker based on Atmel’s ARM Cortex-M0+ MCUs.
  • SAM A5 MPU applications – A new SAMA5D3 Xplained board, a low-cost ARM Cortex A5 processor kit, a smart thermostat, a home automation and smart fridge demo with a 7” capacitive touch panel.
  • 

Atmel’s Wi-Fi connectivity solutions – A Turtle Beach i60 headset and Roku 3 box used on a Vizio M-Series flat panel on display.
  • Atmel SmartConnect Integrates the company’s Wi-Fi technology with a Cortex M0+ core.
  • 
The new SAMR21 family of wireless MCUs (supported by the new SAMR21 Xplained PRO evaluation kits).
  • ZigBee and open-source 6LoWPAN solutions with cloud services.

Other notable demos include Ivee Sleek Wi-Fi, a voice-activated assistance for the home that helps manage and control connected devices without hands; a finger print, voice-search, secure Bluetooth / USB drive that displays passwords; a tiny automatic camera and app that boasts a searchable and shareable photographic memory and a 5mm x 5mm Cortex-A5 System on Module card. 

A polyphase smart e-metering board based on a dual ARM Cortex-M4 core system-on-chip with an integrated metrology AFE will also be on display in the booth.

Along with the new Atmel Studio 6.2 and Atmel-ICE, we will be demoing our latest integrated development platform and advanced debug probe. We will also be highlighting a new SAMA5D3 Xplained cost-effective kit based on the ARM Cortex-A5 processor MPU, as well as the new Xplained Mini ultra-low cost evaluation kit with an Atmel 8-bit AVR, low pin-count MCU for less than USD $10. 

In addition, we plan on hosting several Arduino board demonstrations based onAtmel MCUs for our Maker community.

And, by popular demand, Atmel will also be showcasing its advanced AvantCar demo, a next-generation automotive center console concept with curved touchscreens that illustrates the combined use of Atmel’s XSensemaXTouchQTouch and 8-bit AVR MCU technologies.

Meanwhile, Atmel’s low-power MCU Expert Bob Martin is scheduled to present “Differentiating and Optimizing for Static and Active Microcontroller Modes” during the hands-on workshop: “Applying Optimizing Techniques for Ultra-low Power Microcontrollers” (Class 07) on Wednesday, February 26. In this 9:00 am – 5:00 pm CET day-long session, Martin will be presenting at 9:15 am CET. Last, but certainly not least, Atmel will be announcing winners from its AVR Hero Design contest at the show.
