Demonstrating a Live LoRa IoT wireless network deployed in Munich during the run up to electronica, Semtech was trumpeting its IoT Revolution Ecosystem a the exhibition, announcing partners such as IBM Research, Microchip and their distribution partners.
With a few gateways distributed throughout suburban Munich (including one at the fair), Hardy Schmidtbaur, director of wireless and sensing solutions at Semtech was here to promote the company's partner ecosystem of end-node modules, gateways/concentrators, and network controller solutions for private networks, with a thousand 1,000 IoT demonstration end-nodes to be given away by the ecosystem participants.
During a demonstration, Schmidtbaur was pairing a device to a smartphone, before sending data to the end-node via a remote gateway and pinging back temperature and light levels. Operating in the ISMT 868MHz frequency band using spread spectrum modulation, LoRa can connect reliably hundreds of thousands of sensors over a low power wireless network area spanning 15 to 20km, claims the company, with end nodes remaining operational for over 10 years on two AAA batteries (drawing 10mA for the receiver, under 200nA in sleep mode).
“Our nearest competitor would be Sigfox”, admits Schmidtbaur, “but their solution relies on narrow band Frequency Shift Keying, which is less robust to interferences or jamming”.
“Also, each of their gateway only routes data from tens of thousands of nodes, significantly less than what we can achieve with LoRa”, he added. “This is thanks to LoRa’s adaptive data rate, enabling lower power operation and conversely, better network scalability than competing solutions”, emphasized Schmidtbaur.
Sigfox’ business model is to license IP for others to build the networking RF chips and to bring cloud-based data management services to its customers through the deployment of an IoT infrastructure. The French company claimed victory over some IoT territories with nationwide infrastructures in France, spain and soon the UK by establishing partnerships with local telecom operators.
According to Schmidtbaur, it is very likely that such nationwide IoT infrastructures will be run by today’s telecom operators, since they are the ones who have already secured most of the high points in cities, where transmitters are the most effective. “Each new partnership announcement is akin to a land grab”, he said jokingly.
