The PAN protocol, that was inherently "more secure" because it only reached a few meters? Then, oops, a dude with a yagi could lift stuff from your phone a block away?
OK, it is a small area network, really convenient, and we can make it really low power. Security because of short range is a bad idea anyway.
OOOH! Apple can make it a total coverage network, because every Apple device is a translation node. I can know my ex is in a coffee shop on the other side of the country because I stuck a tag in her glove compartment.
Wait, I can stalk from SPACE!?!?!!?
Of course that really does raise a question, sure, a satellite can send a signal to a Bluetooth device by ignoring the Bluetooth transmit power limits, but I am having a little trouble with an existing Bluetooth device getting a signal back to a satellite, and if you do change the firmware to somehow make a more powerful signal out of hardware that wasn't designed to do that, now you have to plug it into power because the battery lasts half an hour.
And that doesn't even consider the government approval of using that spectrum for a new purpose at a new power level. Sure, it is unlicensed spectrum, but it is still strictly use limited.
Making a few assumptions here, these are going to be LEO devices, yet another constellation to compete with the umpteen other companies that are going to save the future with thousands of flying toasters, and clutter up the view for ground based astronomers?
wow.
