SIGFOX and TI collaborate on long-range, low-power IoT connectivity

Collaboration maximises narrowband radio technology’s superior performance, network capacity, coexistence and total cost for Internet of Things applications

SIGFOX and TI collaborate on long-range, low-power IoT connectivity

Internet of Things (IoT) network provider SIGFOX and Texas Instruments are to work together to increase IoT deployments using the sub-1GHz spectrum. Customers can use the SIGFOX network with TI’s sub-1GHz RF transceivers to deploy wireless sensor nodes that are lower cost and lower power than 3G/cellular connected nodes, while providing long-range connectivity to the IoT.

Targeting a wide variety of end-user applications, including environmental sensors, smart meters, agriculture and livestock sensors, asset tracking and smart cities, the SIGFOX and TI collaboration aims to maximise the many benefits of narrowband radio technology and reduces barriers to entry for manufacturers wanting to connect their products to the cloud.

Using the SIGFOX infrastructure reduces the cost and effort to get sensor data to the cloud and TI’s sub-1GHz technology provides years of battery life for less maintenance and up to 100 km range, the companies claim.

“TI’s sub-1GHz technology is an excellent fit for the SIGFOX network, because it supports long-range and high-capacity connectivity in a system-cost-optimized way that users everywhere require to fully benefit from the potential of the Internet of Things,” said Stuart Lodge, executive vice president of global sales at SIGFOX.

“TI technology that leverages our ultra-narrowband technology is a powerful endorsement and will be a key part of our rapid network deployment in key global markets.”

SIGFOX’s two-way network is based on an ultra-narrowband (UNB) radio technology for connecting devices, which is key to providing a scalable, high-capacity network with very low energy consumption and unmatched spectral efficiency. That is essential in a network that will handle billions of messages daily.

“Narrowband technology is the superior option for a global Internet of Things network, because it offers the lowest-cost, most energy-efficient connectivity, along with the data capacity and robust coexistence, that competing technologies just cannot match,” said Oyvind Birkenes, general manager, Wireless Connectivity Solutions, TI.

“We are excited to be working with SIGFOX to expand their network deployments and bring the benefits of narrowband Sub-1 GHz technology to users worldwide.”

TI’s CC1120 sub-1GHz RF transceiver uses narrowband technology to deliver the longest-range connectivity and superior coexistence to SIGFOX’s network with strong tolerance of interference.

Narrowband is the de-facto standard for long-range communication due to the high spectral efficiency, which is critical to support the projected high growth of connected IoT applications. The CC1120 RF transceiver also provides years of battery lifetime for a sensor node, which reduces maintenance and lowers the cost of ownership for end users.

Sub-1GHz networks
Sub-1GHz networks operate in region-specific industrial scientific and medical (ISM) bands below 1GHz including 169, 315, 433, 500, 868, 915 and 920MHz. The networks are proprietary by nature and provide a more robust IoT connection, which is why the technology has been used for smart metering, security and alarm systems and other sensitive industrial systems. Additionally, the technology is low power, enabling years of battery life to reduce service and maintenance requirements.

Availability
SIGFOX-certified modules based on TI’s CC1120 were demonstrated at Mobile World Congress 2015 and are available today from:
• Adeunis: SI868-25MW for 868 MHz operation
• Radiocrafts: RC1780 for 868 MHz operation
• Telit: LE51-868 S for 868 MHz operation.

Additionally, TI’s CC1120DK and CC1200DK development kits can be purchased through the TI Store or TI authorised distributors to test the capabilities and range of the TI solution.
