Why us for Sub-1 GHz?

We provide a broad portfolio of wireless devices ranging from transceivers to wireless and Multi-band MCUs:

  • Robust software options: out-of-box 15.4-Stack star-network solution and proprietary network support
  • Superior ultra-low power performance over a broad temperature range versus competition
  • Save power with a programmable sensor controller core capable of executing simple tasks while the system CPU and Arm® Cortex®-M4 MCU core are in sleep mode
  • Up to -125dBm sensitivity and data rates up to 4Mbps

Wireless MCUs optimized for ultra-low power performance

Our SimpleLink CC13xx/CC26xx wireless MCUs are designed with ultra-low power performance in mind, utilizing an autonomous CPU core called the sensor controller for power optimization. In the case of a mechanical flow meter with an impeller, the main MCU core could sleep while the sensor controller interfaces with a LC-sensing subsystem to detect disc rotation and provide accurate water flow rate information , only waking up the main MCU core and radio to wirelessly transmit flow measurement. This type of design can enable ultra-low power consumption, ensuring the multiple years of battery life required for flow meters.

  • Based on the IEEE 802.15.4 standard
  • FCC/ETSI certification-ready

Network capabilities

  • Data rates: 50kbps, 200kbps, long range 5kbps, and more
  • Frequency bands: 433 MHz, 863 MHz, 915 MHz
  • Ensures successful transmissions: MAC layer acknowledgments, listen-before-talk and CSMA/CA

SimpleLink Sub-1 GHz: Sensor to Cloud

End-to-end solution for low power wide area networks (LPWAN) enabling cloud connectivity for sending and receiving sensor data over a long range Sub-1 GHz star network.

Sensor to cloud

Sensor nodes

The low-power sensor node example application uses our 15.4-Stack to transmit sensor data from SimpleLink CC13xx wireless microcontrollers. Our 15.4-Stack software is included in the SimpleLink CC13x0 and CC13x2 SDKs.


The SimpleLink Sub-1 GHz Sensor to Cloud gateway is the central node in the star network and acts as a secure bidirectional link between sensor nodes and the cloud.

Cloud partners

The IoT cloud application receives sensor node data from the gateway and communicates it to your choice of cloud-based user interfaces.

Build your own or migrate an existing proprietary Sub-1 GHz network solution

We offer a robust set of proprietary software examples and documentation provided through the SimpleLink SDK and SimpleLink academy that can be used as a foundation for creating  a Sub-1 GHz proprietary network or migrating an existing network.

Packet TX/RX training

Most customizable network solution with access to the RF configuration file and RF Drivers. Send and receive Sub-1 GHz packets within minutes with packet transmission and wake-on-radio examples, and validate your transmission with a packet error-rate meter.

EasyLink network building blocks

Higher level Sub-1 GHz network building blocks that abstract the RF driver layer and provide examples for two way communication with acknowledgments, listen before talk, over-the-air-upgrade, and basic network formation.
