Just listened to this, every smart device in your home is spying on you and sending data out. Wifi/bluetooth/cell phone/smart tv/smart fridge/Alexa/etc. Everything is getting 2 way radios built in that are forwarding traffic along a huge Mesh Network. One person's smart device in their home can now send a signal up to half a mile away, and this also triangulates your own position.
