Something I wonder reading this, hopefully some wireless experts can answer. In theory does locationsmart even need to onboard all telcos for this? Most smartphones have the hardware to talk to all telcos now, and in emergency situations they can roam onto other networks. Do lte devices ping other networks or do they only ping on the spectrum of their particular network? I’ve heard stories of how telcos track down things like broken fridges etc that are adding noise to their network (and buy the owners a new fridge) so clearly they have the ability to track things that aren’t part of their network.
