Partnership Pushes IoT Below 1 GHz

Proprietary sub-1-GHz networks use a minimal amount of power, making them ideal for Internet of Things (IoT) applications. In a collaborative effort to increase the IoT’s presence in that spectrum, Texas Instruments’ (TI) sub-1-GHz transceivers can be used with SIGFOX’s dedicated cellular network to deploy low-power wireless sensor nodes. TI’s CC1120 sub-1-GHz RF transceiver extends the sensor nodes’ battery lifetimes, helping reduce overall maintenance.

The network, when combined with the sub-1-GHz RF transceivers, helps maximize the benefits of ultra-narrowband (UNB) radio technology, supporting long-range, low-power, and high-capacity connectivity. The technology is virtually essential for the network, which is expected to handle billions of messages on a daily basis. Narrowband’s high spectral efficiency makes it the standard for such long-range communications—a major factor in the seemingly infinite increasing number of IoT devices.

The scalable, two-way network offers low energy consumption and high efficiency, according to SIGFOX. Its architecture is optimized for data retrieval from the cloud, opening up a wide range of end-user applications, from environmental sensors, smart meters, and agriculture and livestock sensors to asset tracking and smart cities.
