Long-range Sub-1 GHz Connectivity in the Real World

GUID-F956B82F-C6F8-45FE-91A3-8F1460218979-low.png

Are you looking to connect devices to the Internet of Things (IoT) at a distance greater than 25 km? Or even 100 km?

Then you are probably going to want to add Sub-1 GHz technology to your product to achieve this connection. The combination of long range, low power, software flexibility and operation on a less crowded spectrum make Sub-1 GHz technology ideal for these long-range IoT applications.

TI’s Sub-1 GHz solutions, for operation in 169 MHz, 315 MHz, 433 MHz, 470MHz, 500 MHz, 868 MHz, 915 MHz and 920 MHz ISM bands, provide the longest real-world RF range with a proven distance greater than 100 km.  With long distance, another requirement that is needed is robustness. Our Sub-1 GHz narrowband products provide the distance and robustness to meet any developer’s needs for networks with the lowest power. This means the devices have the ability to transmit at a longer range, at the lowest power consumption, through concrete and cities without interruption from other sources.

To learn more about narrowband, long-range Sub-1 GHz technology read our three-part blog series on Electronic Design which covers different applications where narrowband is the de facto standard:

  1. Why did Europe choose narrowband for long-range smart gas meters?
  2. Why should you use long range narrowband in a smoke detector?
  3. How long range narrowband can improve efficiency in agriculture
