LoRa - and how we utilize it

IoT

14.06.2017

LoRa (Long Range) is a type of modulation used for data transfer. It enables good signal strength over long distances with minimal power consumption. LoRa is based on spread spectrum modulation, in which data transfer between end-devices and gateways is spread out on different frequency channels and data rates. Finnish telecommunications operators are coming out with LoRaWAN™ (Low Power Wide Area Network), which is a LPWAN implementation for local or global networking of devices or in the language of IoT, Things. 

LoRa is reminiscient of our MTR433 technology, but the extremely efficient modulation set it apart especially on bandwidths that see a lot of traffic.

 


Our tests have shown the LoRa technology to complement our existing wireless technologies. It will be used alongside MTR433 and mesh networking when it offers a distinct benefit for an application. LoRa is reminiscent of our MTR433 technology, but the extremely efficient modulation set it apart especially on bandwidths that see a lot of traffic. LoRa enables a good quality data transfer and good signal strength over long distances in relatively open environments. In addition to LoRa, our labs performed tests with Sigfox and determined LoRa to have superior features. We deemed Sigfox's low frequency of data transfers, congested bandwidths and transferring data via multiple countries undesirable and consider LoRa better suited for our needs.

We have traditionally built local networks for environmental surveillance and will continue to do so. Surveilling enviromental data in buildings for example requires large numbers of measurement points. Signal quality and cost effectiveness make a local mesh network an apt solution in such an application. This might change with Digita's future LoRaWAN network. We do not see local networks disappearing completely, but for single measurement point applications the lack of a need for base stations is definite game changer. This will enable effortless surveillance of e.g. public beach water temperatures and water quality.
