This collaboration, say its participants, maximises narrowband radio technology's superior performance, network capacity, coexistence and total cost for IoT applications

SIGFOX, provider of cellular network dedicated to the Internet of Things (IoT), and Texas Instruments have announced the two companies are working together to increase IoT deployments using the sub-1 GHz spectrum. Engineers can use the SIGFOX network with TI's sub-1 GHz 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 maximises 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-1 GHz technology provides years of battery life for less maintenance and up to 100 km range.

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-1 GHz 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.
