  • Up to -125dBm sensitivity and data rates up to 4Mbps

Software solutions for every need

Out-of-box SimpleLink Sub-1 GHz network solution

Developers interested in a pre-built, robust proprietary network that is FCC/ETSI compliant and has security and multi-node capabilities should consider the TI 15.4-Stack, supported on our SimpleLink wireless MCUs. 

Build your own network or migrate an existing one

Proprietary software examples featuring industry-proven RF drivers for developers interested in building their own proprietary network or migrating an existing solution to TI wireless MCUs.

Out-of-box SimpleLink Sub-1 GHz network solution: TI 15.4-Stack

While implementing a Sub-1 GHz network solution can be complex, the SimpleLink Sub-1 GHz stack offers a complete “out of box” standards-based star-network solution for implementing long-range, low power wireless networks in the home, building, or city.

Complete solution

  • Lowers total development cost and reduces time to market
  • Supports 200+ nodes
  • Network management, security, and frequency hopping
  • 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 the TI 15.4-Stack to transmit sensor data from SimpleLink CC13xx wireless microcontrollers. The TI 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

TI offers 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.
