Next-gen LoRa platform aids future IoT devices

 

Supplier of high performance analogue and mixed-signal semiconductors and advanced algorithms, Semtech, has announced its next-gen LoRa devices and wireless radio frequency (RF) technology (LoRa Technology) chipsets enabling innovative LPWAN use cases for consumers with its advanced technology.

Addressing the need for cost-effective and reliable sensor-to-cloud connectivity in any type of RF environment, the new features and capabilities will significantly improve the performance and capability of IoT sensor applications that demand ultra-low power, small form factor and long range wireless connectivity with a shortened product development cycle.

The next-gen LoRa radios extends Semtech’s industry leading link budget by 20% with a 50% reduction in receiver current (4.5mA) and a high power +22dBm option. This extends battery life of LoRa-based sensors up to 30%, which reduces the frequency of battery replacement. The extended connectivity range, with the ability to reach deep indoor and outdoor sensor locations, will create new markets as different types of verticals integrate LoRa Technology in their IoT applications including healthcare and pharmaceuticals, media and advertising, logistics/shipping, and asset tracking.

In addition, the new platform has a command interface that simplifies radio configuration and shortens the development cycle, needing only ten lines of code to transmit or receive a packet, which will allow users to focus on applications. The small footprint, 45% less than the current generation, is highly configurable to meet different application requirements utilising the global LoRaWAN open standard. The chipsets also supports FSK modulation to allow compatibility with legacy protocols that are migrating to the LoRaWAN open protocol for all the performance benefits LoRa Technology provides.

“LPWAN IoT applications are going through a massive transformation, shifting from trials to large deployments in smart cities, buildings, healthcare, logistics, and agriculture,” said Marc Pegulu, Vice President and General Manager for Semtech’s Wireless and Sensing Products Group. “LoRa Technology enables an infinite amount of IoT use cases as Semtech pushes for the last mile of connectivity and reinforces its position as the defacto platform for LPWAN.”

New features:

  • 50% less power in receive mode 
  • 20% more extended range
  • +22dBm transmit power
  • A 45% reduction in size: 4x4mm
  • Global continuous frequency coverage: 150-960MHz
  • Simplified user interface with implementation of commands
  • New spreading factor of SF5 to support dense networks 
  • Protocol compatible with existing deployed LoRaWAN networks.
