The move only applies to connected objects and not to Sigfox’s base stations and infrastructure, as those are protected by patents. Until now, the specification of objects was shared under NDA upon request, while Sigfox wanted to control the number of end-points applying to connect to its network.
"The opening of the specification has always been part of Sigfox’s ambition and we’re excited for the thousands of new use cases that will emerge. Our partners all over the world are looking forward to being part of this development" said Christophe Fourtet, co-founder of Sigfox.
